Avalanche professionals often recommend aluminum over carbon, and slightly beefier probes over flyweight ones. Why? When avy debris sets up after a slide, it becomes extremely concentrated and hard to penetrate, and a burlier probe simply works way better. Why carry a probe all season if it won't even help you find your buddy? The Arva Pro 2.40 Avalanche Probe is a quality 7075 Aluminum that deploys in seconds and will last for years - don't leave the ski area without it.
