1 MOUNTAIN RESCUE SERVICE AVALANCHE PREVENTION CENTER M. Biskupič, F. Kyzek, M. Lizuch, J. Richnavský, I. Žiak Avalanche transcievers test 2015 IKAR Conference 2015, Killarney, Ireland
2 AIMS Present the results obtained during the avalanche transciever test in Zelené pleso (Vysoké Tatry, Slovakia) Test objectives: Verify the transcievers range gained in real conditions Test the funcionality of beacons Comparison of the results from TEST 2011
3 TEST 2015 Test participants: Mountain Rescue Service (HZS), Slovakia Mountain Rescue Service (HS ČR), Czech republic UIAGM (Slovakia) Jagiellonian University in Cracow (Poland) Avalanche Prevention Centre (Slovakia) 10 testers 40 beacons 8 types from 5 manufacturers Randomly 3 from 5 beacons of each type 360 measurements + 28 km
4 TESTED BEACONS TEST 2011 Arva 3 Axes Arva Evo 3 bca Tracker 2 bca Tracker DTS Mammut Barryvox Pulse Mammut Barryvox VS 68 Mammut Barryvox VSOpto 3000 Ortovox 3+ Ortovox F1 Ortovox Patroller Ortovox S1 Pieps DSP v 5.0 Pieps DSP v 6.2 Pieps Freeride TEST 2015 Arva Neo bca Tracker 3 Mammut Pulse Ortovox 3+ Ortovox S1+ Ortovox ZOOM+ Pieps DSP PRO Pieps DSP SPORT
5 METHODOLOGY DAV - Sicherheitsforschung: Range - first signal search Direction - coarse search Accuracy - fine search Multiple burials - direct search
6 RANGE TEST From no signal to receiving the first signal Position of transmitting antenna in 3 axes (X, Y, Z and Ortovox Smart antenna) for each (5) transmitting beacons. DAV - Sicherheitsforschung
7 RANGE TEST IKAR Conference 2015, Killarney, Ireland
8 RANGE TEST Results: Beacon Minimum (m) Transmitter Arva If Neo bca Tracker 3 is 19 transmitting, Mammut Pulse then the best 38 reciever is bca. 40 In all other sitiuations the best reciever is Arva Neo. Beep and Stable signal Calculated search strip width (m) Difference from the actual distance and the distance of the Ortovox S1+ 17 Mammut Pulse beacons display Ortovox ZOOM+ 11 Arva Neo Beep X (m) Signal X (m) Beep Y (m) Signal Y (m) Beep Z (m) Signal Z (m) The recommended search strip width and reality Width according to the manual (m) Beacon Axis X (%) Axis Y (%) Axis Z (%) Average (%) Arva Neo Bca Tracker 3 15 Arva Neo bca Tracker Mammut Pulse 16 Pieps DSP PRO Mammut Pulse Ortovox Mammut Pulse Ortovox Ortovox S Ortovox ZOOM Pieps DSP PRO 16 Arva Neo Test 2011 Pieps DSP SPORT 17 Arva Neo (10 Pieps types DSP of beacons) PRO Test Pieps 2015 DSP SPORT (8 types of beacons) TOTAL 83
9 DIRECTION TEST Stable signal to immediate vicinity of search target DAV - Sicherheitsforschung
10 DIRECTION TEST Axis Axis
11 DIRECTION TEST Results: If the transmitter antenna in Z axis this means most unfavourable possition of all (for the victim and for the rescuer) Time of search increase Distance is longer Test 2011 vs without improvement
12 ACCURACY TEST IKAR Conference 2015, Killarney, Ireland
13 ACCURACY TEST IKAR Conference 2015, Killarney, Ireland
14 ACCURACY TEST Results: Simply, most of the beacons has displayed shorter distance than real one, approximatelly %. Keep this fact in mind when probing!

17 MULTIPLE BURIAL TEST (GPS measurement) Results: All beacons have found all 3 buried beacons except bca Tracker 3. Marking function has been improved! This result is a major improvement regarding results of 2011 testing! bca Tracker 3 is able to mark only once at a time!
18 CONCLUSIONS RANGE TEST Improvement only in Y axis Differences between real distance and displayed one is bigger then in 2011 Test Width of search strip is misleading according to manuals DIRECTION TEST Unfavourable possition Z axis without change ACCURACY TEST Without major changes MULTIBURIAL TEST Over all improvement, all buried beacons detected. Different marking function manufacturer approach causes time delay (bca)
