Frequently Asked Questions (FAQs)
What’s the difference between a supercapacitor and compressed air airbag?
A supercapacitor system, like the Alpride E2 in the BCA E2-35, E2-25, and Mtn Pro, uses an electric fan to inflate the airbag. It’s powered by a supercapacitor (recharged by AA batteries), is not affected by cold, and can be deployed multiple times for practice. Compressed air systems, like the Float 2.0 in the Turbo 25 and Float 15, use a one-time-use cylinder of compressed air to inflate the bag, which must be refilled or replaced after every deployment.
Are electronic avalanche backpacks allowed on airplanes?
Yes, electronic systems like the Alpride E2 are generally airline-friendly. Because they don’t use compressed gas cylinders or pyrotechnics, they are not subject to the same restrictions. You can typically fly with them in your checked or carry-on luggage without issue, which is a major advantage for traveling skiers.
How many liters do I need for an avalanche backpack?
This depends on your objective. A 15-25 liter pack (like the Float 15 or E2-25) is ideal for sidecountry, day tours, or minimalist trips. A 35-liter pack (like the E2-35) is better for longer, full-day tours or professional use where you need to carry extra layers, more food, a rope, or group safety gear.
What is the Float 2.0 system?
The Float 2.0 is Backcountry Access’s mechanical avalanche airbag system. It’s a proven, reliable design that uses a compressed air cylinder (sold separately) to inflate the airbag. It’s trusted by many professionals for its simplicity and dependability in any condition.
Why choose an airbag vest over a backpack?
An airbag vest, like the BCA Float E2 Mtn Pro, integrates the pack and airbag system into a vest that wraps around your torso. This distributes weight more evenly, reduces back strain, and provides superior balance and mobility for aggressive skiing or snowboarding. It’s often preferred by guides and professionals who spend long days on the snow.
