How to Choose an Avalanche Probe 

I WOULDN'T GO ANY SHORTER THAN A 300 CM ALUMINUM PROBE PLUS WHEN YOU CARRY IT IN YOUR PACK DO NOT PUT IT IN YOUR SLEVE AND THEN PUT IT IN YOUR PACK WHY,IN A EMERGENCY SPEED IS THE NAME OF THE GAME!YOU NEED TO GET THAT PROBE OUT A.S.A.P. WITHOUT TAKING IT OUT OF ANOTHER SLEVE WITH MITTENS/GLOVES ON,PERIOD!
