dary search 2 - Final search (last cross) 3 1 2 3 4 5 6 7 8 9 10 11 12 using the arvaA The ARVA ADVANCED has two operating modes:
Standard (numerical), involving use of the right and left directional arrows. The device automatically locks on to the closest victim. Follow the indi-
cations given in the form of figures and the direction shown by the red diode. If pictogram 6 lights up, the device has detected multiple victims. Advanced (analogue with numerical aids), in which receiver sen-
sitivity is adjusted with the + and - buttons. In analogue mode, the Advanced symbol is displayed on the screen with a sensitivity level value (1,2,3,4,5,6,7,8 or 9). 9 corresponds to greatest sensitivity (distant search) and 1 to lowest sensitivity (close search). In this mode, the device shows all the signals received. If there are multiple victims, it indicates the estimated distances to each one. Exclusive features of the ARVA Advanced:
A powerful 457 kHz 20 Hz transmitter with transmission level inde-
pendent of battery power. In numerical (standard) mode, the search band width is 40 m. Multiple victim indicator and automatic synchronisation on closest victim. In Advanced (= analogue) mode, indication of a scale of progress and, in multiple victim situations, indication of estimated distances along field lines. Auto-control of frequency adjustment and transmission level every 5 minutes. 16 bit processor with extremely fast analysis speed. switching the unit on Fasten the On/Off strap 1 Auto-control: the direction diodes 3 light up from left to right, and the LCD screen comes on. 3 beeps are emitted if the loudspeaker is in working order. Check your batteries using the battery life indicator scale levels 8 9 11 levels: 99,90, 80, 70, 60, 50, 40, 30, 20, 10, 0. The LCS screen then goes off and the central diode 3 flashes to indicate that the unit is in transmit mode. Check Transmit/Receive functions before setting out. The per-
son checking the unit puts his ARVA in transmit mode and all the other members of the group check that their ARVAs detect the signal properly in receive mode . The operation is to be repeated in the opposite direction so that ALL the ARVA units in the group are checked in both transmit and receive modes. Possible anomalies... The ARVA ADVANCED performs a self-test every 5 minutes to check the state of the batteries, frequency setting, transmission power, etc. If the unit detects an anomaly, a 5-second beep is emitted, 3 times, separated by 5 minute intervals. This means one of two things:
The battery charge has dropped to 20% (the unit can still transmit for 48 hours or search for half an hour). After the 5-second beeps, 20% will stay displayed on the LCD screen to remind you to change the batteries as soon as possible. Technical problems connected with transmission or programming: after the 5-second beeps, the LCD screen displays Er (= Error). Do not set out with any unit displaying this message. installing batteries information for your own safety The ARVA ADVANCED operates exclusively with four standard LR03 alkaline batte-
ries. Open the battery compartment cover 11 with a screwdriver or coin. The four batteries should be of the same brand and be replaced at the same time. Insert the batteries carefully in the order shown inside the compartment. N.B.: Do not store the unit at a temperature of less than 0C to avoid damaging the batteries. DO NOT USE rechargeable batteries. Remove the batteries if the unit is not used for any length of time. useful information:
Move forward SLOWLY to avoid going too hastily in the wrong direction. The entire surface of the avalanche must be investigated. When searching for a victim or testing the unit, stay away from electrical equipment (high-voltage power lines, radios, mobile phones, etc.) or impose radio silence (these are just a few examples). This is applicable when using any ARVA-type transmitter-receiver. The distance indicator indicates progress along a field line and not a distance in metres. Whenever you leave marked-out ski runs or trails, you are in an area where there are certain risks, particularly of avalanches. When moving around in the mountains, you do so at your own risk:
Before setting out, check the local weather with a reliable weather station or pro-
fessional mountain guides and carry the right equipment. In particular, take an ARVA and carry a shovel and a probe. But remember, this equipment will not detect avalanches or provide complete protection and to be fully effective, you need to familiarise yourself with the use of the ARVA beforehand!
Never go off on your own and do not follow any trail you happen to see: they are no guarantee of safety. If there is any doubt about the stability of a slope you have to cross, YOU MUST leave a good distance between one another or better, cross it one by one. Keep a good eye on one another. Finally, it is best to give up if you are not sure! Be careful: snow conditions change, and with them the risk of avalanches. Get to know about avalanches. In France, a free cata-
logue and documentation can be obtained from ANENA (Association Nationale pour lEtude de la Neige et des Avalanches, - tel. 04 76 51 39 39 / www.anena.org). Simply press simultaneously on the + and - buttons for 3 seconds to flip from Standard (nume-
rical) mode to Advanced (analogue) mode (Advanced logo and sensitivity level are displayed on the LCD screen). Repeat this operation to return to numerical mode (the logo and sensitivity level disappear from the LCD screen). This can be done at any time, even if rescue workers have begun their search in Standard (numerical) mode. We shall now take a look at the two main modes and study an example of a search in the case of multiple victims. The cases presented are typical ones. With training and experience, the user can change from Standard (numerical) mode to Advanced (analogue) mode depending on how familiar he is with the device and the situation in which he finds himself. Case of a single victim english D standard (nu-
merical) mode Primary search (approach phase) (cf D1) Pull 2 SEARCH.- The device is automatically in completely automatic numerical mode. The LCD screen displays the arrow diagram continuously until you pick up a signal from the victim. Move backwards and forwards across the avalanche as shown in diagram B if you are the only rescuer or diagram C if there are several rescuers. Hold it downwards (cf. photo), and sweeping it slowly from left to right and right to left (making an angle up to 180) the ARVA horizontally, pointing Continue until you pick up a first clear signal
(directional arrows and distance indicator light up) N.B: If the ARVA has already picked up a signal it will go directly to the secondary search. Secondary search (locating phase) (cf D2). This phase starts when the victims signal has been picked up. The ARVA gives you a distance indication on the LCD screen and one of the directional arrows lights up. As soon as one of the directional arrows lights up, point your ARVA in such a way that the central diode lights up and head in that direction. If the numbers decrease, you are mo-
ving closer to the victim. If not, go in the opposite direction. Always try to make sure that the cen-
tral diode is lit. Sweep the unit gently in the directly in which the arrows light up. This will ena-
ble you to cover the shortest possible distance be-
fore reaching the victim. Continue moving forward until the distance indicator displays 3.0. Final search (detection phase) (cf D3) At this point, with the arrow lit up, lower the ARVA unit as close as possible to the snow, pointing it in the same direction and keeping it horizontal. The beeps become faster and the distance indicator keeps decreasing. Keep moving forwards as long as the number decreases. If it starts to increase, return to the point where it is smallest and locate the victim using the cross technique, always pointing the ARVA in the same position. Cross technique: The ARVA must be moved as closely as possible to the snow, in parallel straight lines. Determine the point along the line where the distance indicator displays the smallest number and the beeps are emitted very close together or continuously. From that point, move perpendicularly and repeat the operation. The point at which the maximum signal is obtained is vertically above the transmitter. If necessary, re-
peat the operation once or twice to obtain a more precise position. However, it is not necessary to determine an extremely precise location using the ARVA. In fact, it is usually faster to start searching with a probe as soon as the likely location has been determined to within about 50 cm. E advanced (ana-
logue) mode Diagrams E1 and E2. When the ARVA is switched to advanced mode, its sensitivity is maximum (level 9). However, the Advanced symbol flashes if the sensitivity level is to be reduced. Decrease the sensitivity with the - button until the symbol stops flashing. When the symbol stops flashing, you can use the numbers, which give an estimation of the distance that still needs to be covered. Initial search Moving forward, turn the device in every direction until the first audible signal is heard. If the signal is weak, continue to move in the same direction without changing the position of the device until the sound is clearer and sufficiently distinct to be of help. The initial search is over when a clear signal is obtained. Secondary search (cross or directional search) There are two possibilities:
Cross technique Diagram E1:
As you move forward, keep the ARVA in the same position. It must be moved parallel to itself. When the first signal is obtained, keep moving in a straight line. The beep becomes louder and the distance indicator decreases. Once the maximum signal has been reached and starts to diminish, return to the approximate point where it was strongest. Reduce the sensitivity to minimum in order to detect the point where the beep will be loudest, and start moving in a line perpendicular to the previous direction. You will soon realise if you are moving in the right direction, as the signal will quickly become louder, or in the wrong direc-
tion, in which case it will diminish. Once again, find the point where the beep is loudest, as pre-
viously. Continue until the sensitivity is positioned on one of the two last levels (minimum sensitivity, and therefore minimum search distance). Directional method Diagram E2:
To determine the direction to follow, sweep the ARVA from left to right over 180, holding it horizontally. The stronger the signal, the louder the beep will be (and the lower the distance in-
dicator). The right direction is the one in which the beep is the loudest. If the beep gets louder as you move forward, you are going in the right direction. If it gets weaker, you are going in the wrong direction. Turn round, walk back a few me-
tres and check again to find the right direction. As you advance, turn down the sound level with the - button (so that it is easier to determine where the ARVA is emitting the loudest beep). When the sensitivity is down to 2 or 1, the secon-
dary search is finished. Final search You are very close to the victim when the sensiti-
vity is down to 2 or 1 (the actual level depends on the depth at which the victim is buried). The cross technique should then be used (see opposite). Re-
member that in this case the distance indication is replaced by the intensity and frequency of the beeps. The closer you get to the buried victim, the louder and faster the beeps are emitted. When the distance between the transmitter and receiver is very small, a single continuous beep is emitted. Situations with multiple victims ... F N.B: This is one possible method for finding victims. The user may decide to stay in Advanced mode for the entire search and adjust the sensitivity level with the +
and - buttons to isolate signals from different victims Start with the initial search if necessary, in either Standard (numerical) mode or Advanced
(analogue) mode. In the secondary search phase, if indicator 6 is lit, this means that the ARVA is picking up several signals around you, mark the area with a ski or pole (F2). In standard mode, the ARVA will automatically lock on to the unit emitting the strongest signal, which is theoretically the victim closest to you. Once you have found the first vic-
tim (F3/v1), locate him using your snow probe and mark the location Return to the point that you marked earlier and switch the ARVA to Advan-
ced (Analogue) mode (F4): the unit will indicate the various signals it has picked up. Several estimated distances are displayed, along with various levels of sound depending on how close they are. N.B As soon as you switch to Advanced mode, the unit will automatically revert to sensitivity level 9
(maximum range). Use the - button to lower the level and search for the second victim. When you pick up the signal from the second victim, two estimated distances will be displayed on the LCD screen. To obtain a closer estimate, reduce the sensitivity until the victims signal is barely audible and focus on the higher figure (the lower figure with a strong signal corresponds to the first victim v1 and the weaker signal to the distance of victim v2). Determine the direction to follow by sweeping the ARVA from right to left and attempting to reduce the distance of the higher figure. Once you have found the right direction, move forward, taking the number of steps indi-
cated. One of the figures will increase and the other decrease, while at the same time one of the signals will increase and the other decrease. When you have taken the number of steps indi-
cated, switch to Standard (numerical) mode (F5). Make a SLOW sweep with the unit. The ARVA will automatically lock on to the closest victim, i.e. the second one. Repeat the standard mode search, as in the case of a single victim. If you return towards the first victim, go back to the starting point (where you obtained the multiple victim signal) and try to find the direction for the second victim in Advanced mode. N.B. In the case of multiple victims, it is advisable to use an earphone to distinguish the various signals more clearly.

Dans ce mode lappareil vous donne tous les signaux reus. Si vous tes dans un cas de multi-ensevelissements, lappareil vous donne des estimations de distances des diffrentes victimes. mise en place des piles LARVA ADVANCED fonctionne exclusivement avec 4 piles Alcaline LR03 standard. Ouvrez la trappe daccs aux piles 11 avec un tournevis ou une pice de mon-
naie. Les 4 piles doivent toujours tre de mme marque et remplaces en mme temps. Introduisez les piles soigneusement dans le sens indiqu lintrieur du logement. N.B. : Ne pas stocker lappareil une temprature infrieure 0 C pour ne pas dgrader les piles. EVITER ABSOLUMENT les piles rechargeables. Enlever les piles en cas de non utilisation prolonge. quelques conseils pour lutilisation :
Evoluer sur le terrain LENTEMENT pour ne pas prendre de fausses directions dans la hte. La totalit de la surface du dpt de lavalanche doit tre prospecte. Lors dune recherche ou dun contrle, veillez : rester loign de tout appareil lectrique (ligne haute tension, radio, tlphone portable) ou faire un silence radio. Cette liste est non exhaustive. Ceci sapplique pour tout appareil metteur-rcepteur de type A.R.V.A. Lindicateur de progression donne un indice de progression sur une ligne de champ et non une distance en mtres. Les EXCLUSIVITES de l'ARVA ADvanced :
Un metteur 457 kHz 20 Hz trs puissant dont le niveau dmission ne dpend pas de ltat des piles. En mode numrique (mode standard), la largeur de bande de recherche est de 40 m. Un indicateur de prsence dun multi-ensevelissements et une synchronisation automatique sur la victime la plus proche En mode Advanced (= analogique), affichage dune chelle de progres-
sion et lors de multi-ensevelissements, affichage dune estimation de leurs distances selon la ligne de champ Un auto-contrle du calage sur la frquence et de la puissance dmission toutes les 5 minutes Processeur 16 bits avec vitesse danalyse extrmement rapide mise en route Bouclez la sangle Marche/Arrt 1 Auto contrle de lappareil : les diodes de direction 3 vont sallumer de gauche droite ainsi que tout laffichage de lcran LCD. 3 Bips pour le con-
trle du haut parleur vont se faire entendre quand il est en bon tat. Contrlez vos piles grce lchelle de valeur en pourcentage de qualit des piles 8 9 . 11 niveaux (99, 90, 80, 70, 60, 50, 40, 30, 20, 10, 0). Ensuite lappareil teint lcran LCD et la diode centrale clignote 3 pour indiquer que lappareil est en position mission. Contrle Rception/Emission effectuer au dpart de chaque sortie. Le contrleur met son ARVA en mission et chaque membre du groupe vrifie que son ARVA en rception le dtecte bien. Opration renouveler dans lautre sens pour que TOUS les ARVA du groupe soient contrls en mission et rception. Anomalies possibles... LARVA ADVANCED procde un auto-test toutes les cinq minutes vrifiant ltat des piles, le calage de la frquence, la puissance dmission, etc. Si lappareil dtecte une anomalie, un long bip de 5 secondes se fait entendre, 3 fois spares par 5 minutes. Deux cas possibles :
Etat des piles descendu 20% (lappareil peut encore mettre 48h ou recher-
cher pendant 12 heure). Aprs les longs bips de 5 secondes, 20% restera allum sur lcran LCD pour vous rappeler de changer les piles au plus vite. Problmes techniques dmission ou de programme, aprs les longs bips de 5 secondes, lcran LCD affiche Er (= Error). Ne partez pas avec cet appareil dans ce dernier cas. informations pour votre scurit Quand vous sortez des pistes de ski scurises, vous entrez dans un monde risque, o une avalanche, en particulier, peut se produire. Vous circulez alors en montagne sous votre propre responsabilit :
Avant de partir, informez-vous (rpondeur tlphonique au au 0 892 68 10 20, www.meteo.fr et professionnels de la montagne) et quipez-vous. En particulier, portez sur vous un ARVA (appareil de recherche de victimes davalanche), une pelle et une sonde. Cet quipement nest pas un dtecteur davalanche, ni une protection absolue, Mais attention, pour tre efficace, il faut tre entran : exercez-
vous donc utiliser votre ARVA !
Ne partez jamais seul, ne suivez pas nimporte quelles traces : elles ne sont pas une garantie absolue de scurit. En cas de doute sur la stabilit dune pente que vous devez absolument emprunter, augmentez les distances entre vous, ou mieux, ne passez quun par un. Et surveillez-
vous mutuellement. Enfin, sachez renoncer... Soyez vigilants : la neige change, le risque davalanche aussi! Apprenez donc mieux connatre les avalanches (catalogue gratuit et documentation lANENA, association natio-
nale pour ltude de la neige et des avalanches, au 04 76 51 39 39 et sur www.anena.org) Passage du mode standard (numrique) en mode Advanced (analogique) par simple pres-
sion simultane sur les touches + et - de lappareil pendant 3 secondes (affichage du logo Advanced et sensibilit sur cran LCD) et retour en mode numrique par la mme opration (disparition du logo Advanced et sensibilit sur cran LCD). Cette opration est possible tout moment, mme pour les chercheurs ayant prfr commencer une recherche en mode Standard (numrique). Nous allons dtailler les deux modes principaux ci-dessous et tudier un cas de recherche lors de multi ensevelissements. Les cas prsents sont des cas types . Aprs entranement, lutilisateur pourra quand il veut passer du mode standard (numrique) au mode Advanced (analogique) selon son entranement avec lappareil et les scnarios de recherche rsoudre... Cas dune seule victime ensevelie franais D mode standard
(numrique) Recherche Primaire (Phase dapproche) (cf D1) Tirez sur 2 SEARCH.- Lappareil est automatique-
ment en mode numrique compltement automati-
que, lcran LCD affiche (dessin flche) en continu tant que vous navez pas dtect de signal mis par la victime Evoluez en quadrillant lavalanche selon le sch-
ma B si vous tes seul ou C si vous tes plusieurs sauveteurs. Tenez lARVA horizontalement, en le pointant vers le bas en balayant lentement de gauche droite et de droite gauche (vous pouvez faire un angle de 180) Continuez jusqu avoir un premier signal net et clair (flches de direction sallumant ET indicateur de progression). N.B : Il peut arriver que vous soyez directement en recherche secondaire, lARVA captant un signal ds sa commutation en rception. Recherche secondaire (phase de localisation)
(cf D2). Cette phase commence partir du moment o vous recevez le signal de la victime. LARVA vous donne une indication de progression sur lcran LCD (chiffres) ET lune des flches de direction sallume. Ds quune flche de direction sallume, orientez votre ARVA de telle sorte que la diode centrale soit allume et partez dans la direction ainsi indique. Si les chiffres diminuent, vous vous rapprochez de la victime, continuez dans cette bonne direction. Sinon, partez en sens inverse. Chercher toujours allumer la diode de direction centrale pour progresser, oprez alors un balayage lger dans le sens o les flches sallument. Ceci va vous permettre de parcourir le moins de distance possible jusqu la victime. Continuez avancer jusqu ce que lcran de pro-
gression affiche 3.0. Recherche finale (phase de dtection) (cf D3) Arriv cet indice, flche allume, descendez lARVA horizontalement et dans la mme position au ras de la neige. Les bips sacclrent, lindice de progression diminue encore. Continuez la progres-
sion jusquau plus petit chiffre. Lorsquil augmente, revenir au plus petit et localisez alors la victime par la technique de la croix en gardant cons-
tamment lARVA dans la mme position. Technique de la croix : LARVA doit imprative-
ment tre dplac au ras de la neige, paralllement lui-mme sur une ligne droite. Sur cette droite, il faut dterminer lendroit o lindication de pro-
gression est la plus faible (bips trs rapprochs, voire continus). De l, partir la perpendiculaire et renouveler lopration. Le point de son maximum alors dtermin est la verticale de lmetteur. Sil le faut, renouveler lopration une ou deux fois de plus pour affiner la localisation. Mais, il nest pas ncessaire darriver une localisation extrmement prcise laide de lARVA. Il est en effet souvent plus rapide de commencer immdiatement sonder ds que lon a dfini la zone probable de localisa-
tion avec une prcision de 50 centimtres environ. E mode advan-
ced (analogique) Schmas E1 et E2. Ds que lArva est commut en mode advanced, sa sensibilit est maximale (niveau maximum 9). Ce-
pendant lappareil vous indique quand diminuer la sensibilit par le clignote-
ment du pictogramme Advanced. Tant que le pictogramme clignote, diminuer la sensibilit avec la touche -, lorsque le pictogramme ne clignote plus, vous pouvez alors vous aider des chiffres qui vous donnent une esti-
mation de la distance restante parcourir. Recherche Primaire Tout en se dplaant, on oriente lappareil dans toutes ses positions dans lespace (dans tous les sens) jusqu rception dun premier signal
(sonore). Si le signal est faible, sans modifier la position de lappareil, on poursuit sa progression dans la mme direction, jusqu le percevoir plus nettement. Il doit tre suffisamment net pour tre exploitable. La rception dun signal net marque la fin de la recherche primaire. Recherche secondaire (croix ou directionnelle) Deux mthodes :
Mthode en croix Schma E1: Pendant le dplacement, ne pas modifier la position de lARVA:
il doit tre dplac paralllement lui-mme. A la rception du premier signal, le chercheur continue tout droit. Le bip crot (et lindice de progression diminue), passe par un maximum puis commence dcrotre. On revient au point approximatif dinten-
sit maximum (ventuellement dfini par un nou-
veau dpassement). De ce point, partir angle droit par rapport la direction de marche prcdente, aprs avoir baiss la sensibilit jusquau minimum audible (pour bien entendre lendroit o le bip sera le plus fort). On se rend compte trs vite si lon est parti du bon ct (signal sonore qui augmente dintensit) ou du mauvais ct (perte rapide du signal). On recherche alors sur cette nouvelle di-
rection le point dintensit maximum du bip sonore comme prcdemment. Poursuivre ainsi jusqu ce que la sensibilit soit positionne sur lun des deux derniers niveaux (sensibilit minimale, donc porte de recherche minimale). Mthode directionnelle Schma E2: Pour dterminer la direction suivre, on fait pivoter lArva devant soi sur 180, sur un plan horizontal. Dans ce cas, plus le signal reu est fort, plus le bip sonore est fort (et plus lindication de progression est faible). La direction suivre correspond donc celle qui donne le bip sonore le plus fort. Quand on se dplace, si le bip sonore augmente, le sens de progression est le bon. Par contre, si le bip sonore diminue, le sens de progression est mauvais : il faut faire demi-tour et partir dans le sens oppos. On se dplace de quelques mtres dans cette direction puis on refait le point pour dterminer la nouvelle direction suivre, etc. Au fur et mesure de la pro-
gression, on rduit lintensit du son avec la touche
- (pour mieux dterminer la position de lArva pour lequel le son est maximum). La sensibilit sur 2 ou 1 marque la fin de la recherche secondaire. Recherche finale La sensibilit sur 2 ou 1 (selon la profondeur den-
sevelissement) signifie que lon est aux environs immdiats de la victime. La technique utiliser est celle de la croix (voir ci-contre), sachant que lindication de progression est remplace dans ce cas par lintensit et la frquence des bips :
plus on se rapproche de la victime ensevelie, plus les bips sont forts et plus la frquence des bips est grande (quand la distance entre metteur et rcepteur est trs faible, il ny a plus quun seul bip long et continu). Cas de plusieurs victimes ensevelies ... F N.B : Cette mthode est une des mthodes possibles pour rsoudre le cas. Selon lutilisateur, celui-ci pourra dcider de rester en mode Advanced toute sa recherche et jouer avec la sensibilit (touches + et - ) pour isoler les signaux des victimes. Commencer par votre recherche primaire si be-
soin est, en mode standard Numrique ou en mode Advanced Analogique (F1). Dans la phase de recherche secondaire, lorsque le voyant 6 est allum, ceci veut dire que votre appareil a dtect, au moment o il sest allum, plusieurs missions autour de vous, marquer alors cette zone avec un ski ou un
(F2). En mode standard, lappareil va bton automatiquement se caler sur lappareil qui met le plus fort donc thoriquement, la victime la plus pro-
che de vous. Vous avez trouv la premire victime
(F3/v1), localisez la avec votre sonde et signalisez lemplacement. Revenez alors au point marquant la dtection du multi ensevelissements et passez en Mode ADVANCED (Analogi-
que) (F4) : lappareil va alors vous donner les diffrents signaux reus : plusieurs estimations de distances vont apparatre ainsi que des sons plus ou moins forts selon leurs proximits. N.B. Ds le passage en mode Advanced, lappareil sera automatiquement en sensibilit 9 (porte max), diminuer alors avec la touche - la sensi-
bilit pour rechercher la deuxime victime. Ds la dtection de la deuxime victime vous aurez deux estimations de distance sur lcran LCD. Pour affiner ces distances, diminuez la sensibilit jusqu avoir la deuxime victime peine audible et concentrez vous sur le plus grand chiffre. (Le plus petit chiffre avec un son fort correspond la vic-
time que vous venez de trouver v1 et lautre chiffre avec un son plus faible correspond lloignement de la victime v2). Dterminez alors la bonne di-
rection suivre en balayant avec votre appareil et en essayant de faire baisser la distance du plus grand chiffre. Une fois la bonne direction trouve, marchez, dans cette direction, en effectuant le nombre de pas correspondant au chiffre annonc. Un des chiffres va augmenter et lautre diminuer, de mme, un des signaux sonores dune des victimes va augmenter et lautre diminuer. Une fois le nombre de pas effectu, passez en mode Standard (numrique) (F5), balayez LENTE-
MENT, lappareil va automatiquement se caler sur la victime la plus proche qui est donc votre deuxime victime. Reprenez alors la mthode de recherche en mode standard, cas dun seul ensevelissement. Si vous revenez sur la premire victime trouve, repartez au point trouv au dpart (l o vous aviez le signal densevelissement multiple) et essayer de retrouver la direction de la deuxime victime en mode Advanced. N.B. Il est conseill dutiliser une oreillette dans le cas dun mutli ensevelissements pour une meilleure concentration sur les diffrents signaux.
