My probe is 320cm, but realistically speaking, if you're digging up someone buried 300cm, you're likely going to be digging up a corpse. They're just too deep. It's gonna take too long.
if you hold a tape measure in your hand and let it drop to the floor you'll be holding 75-100 cm of tape in your hand if you remain upright. in a probing situation are you going to go down to one knee driving your hand to the top of the snow each time you probe or are you going to remain standing?
i think its a silly argument to go short. are any of you really that concerned over the weight of two more fucking tent poles? would you accept a beacon with 30% less range? an airbag with 30% less capacity just so it will weigh 5% lighter?
