On my trip to St Anton me and my mate did a tranceiver recovery test.
Up on Rendle there is a football pitch sized area wit buried bleepers. You can select number of victims ( 1 – 5 ) and time to find ( 1 – 20min ) .
First go not so good, spend too long faffing with probes and didnt have a defined search plan so around 5 mins to locate and switch off the bleeper by lancing it 3 times with a probe.
Second time much better , dialled in 2 victims and 10 mins . Probed out the first box ( imagine a cake tin 30 cm down ) in 3 mins , then completed the second find in 7 mins.
Interestingly my Ortovox M2 is less sensitive than my mates , he gets the first indication maybe 5meters further out than me, but when it gets up close and personal mine is better , showing down to 20cm from source if using a slow moving arc .
You are not allowed to dig out the boxes so not a true representative sample, but locating a victim and leaving a shovelling team in place survival chances massively increased.
We had a good time , although I had a big high speed crash on sat afternoon and might have snapped torn my left UCL thumb tendon. Its OK though , having snapped the right hand one twice i now have non opposable thumbs and have regressed down the evolutionary ladder to the chimpanzee level. But it might just be torn a little bit and the doc on monday can refer me to surgery or not.
