anything actively sending out radiosignals is likely going to interfere with your beacon ...
that being said the interference is usually negligeable ....
and about the recco things, do you carry a recco on your body when you go freeriding ? or only a beacon ? if you don't have a recco now your argument is pretty much invalid cause then it wouldn't change a thing.... (except the searchparty will now find a nice pair of skis)
and also, recco avalanche victim recovery is almost always too late ....
+ if you already have a beacon on yourself, that would be the first thing they would start scanning for, not recco ....
but yeah, i don't think it's going to be easy to 'borrow' skipatrol's recco finder to look for lost skis ....
