[QUOTE="telistomas, post: 937335, member: 90268"] 2009 Transceiver Test Assessing the New Three-Antenna Transceivers F. M. Swangard MD1, Bob Sayer2, Steve Gunderson3 Abstract There has been a great deal of change since the last transceiver test which the Canadian Ski Patrol presented in 1999.4 Transceivers have changed in their technical construction and as a result of these changes there has been a profound change in how they are used. A number of extra features have been added which may improve finding a buried person. We tested the most common five new transceivers used in BC against the Ortovox F1, an older, single antenna transceiver, which is most commonly used in BC. We first tested the transceivers with 15 certified ski guides who in their workplace used the Ortovox F1. Each guide used all six transceivers in a simulated avalanche.5. The times to find the two buried transmitters were recorded. We then performed the same program with 15 high school students who had never used transceivers. We staged it so that the novice high school students were divided into three groups, each of which used the transceivers in a different sequence to rule out a learning advantage by using the transceivers in the same order. The results showed only a small difference in the times of the guide using the new models, with the Ortovox d3 being the fastest and the F1 the slowest even though the F1 is the transceiver they used most often. The results with the students was most interesting. Only four out of ten (two of the three groups) were able to find the second buried transmitter within the seven minute time limit using the Ortovox F1. All students were able to find all the targets with their new model transceivers in their test group. The fastest times were with the Ortovox S1which was slightly faster than the Ortovox d3, Mammut Pulse, Tracker DTS, and the Pieps DSP which finished in that order and quite close together. Clearly the new transceivers are much better in the hands of a novice or irregular user.
