Carabiners and locks are both crucial pieces in our travel kit, but carrying a lock is a drag. Locks are cumbersome, slow to use, uninspired, and often get left behind as a result. The BetaLock was designed to address exactly that. It works perfectly as a rugged EDC carabiner and transitions seamlessly into a theft-deterring lock at the turn of a key. It's lightweight and multi-use so there's no reason to leave it behind. The most effective lock is the one you have on-hand when you need it.
