I'll take that challenge on the SOS verse my Pulse any time of the day ! Bring it, don't sing it ! Just because your proficient in using it doesn't make it fast. ?Range, ease of find, speed and also the fact that your old beacons are old (they may not work like they did when they were new, sending and receiving) make them dangerous to you and others around you.
Ask any good Avy instructor and he/she will tell you its time to get rid of the old style beacons and crews will become more proficient, and reduce errors in searches. Just ask or better yet take AST1 and go out in the field and watch why your single antenna beacon is dangerous ! I watched 3-4 guys in our AST1 throw there old SOS beacons away after the course and purchase new Pulses/DSP's. It just makes sense
We don't let guys in our group ride with analog single beacons. I'd rather dig up a spare new one and know i have just that much better of a chance of being found !
