K2 Carbon Probe 300: We hope the only thing you need to use an avalanche probe for is to collect snow pit data and identify crevasses. Unfortunately, emergencies do happen and in the case of one, you want to have the best available equipment on the market. The K2 Carbon Probe 300 is a one of a kind model that is the lightest and most durable probe on the market. Don’t bother with the cheapo fragile probes because, in a life or death situation, it is not worth having anything shy of the top of the line equipment.
