METHODOLOGY
DAV - Sicherheitsforschung:
• Range - first signal search
• Direction - coarse search
• Accuracy - fine search
• Multiple burials - direct search

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.

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. 2015 - without improvement

Results:
• Simply, most of the beacons has displayed shorter distance than real one, approximatelly 10 – 20 %.
• Keep this fact in mind when probing!

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!

CONCLUSIONS
IKAR Conference 2015, Killarney, Ireland
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)
