Black Diamond Magnetron Carabiner
Tired of messing with twistlocks, screwlocks, or, worse yet, no-lock carabiners? The Black Diamond Magnetron Carabiner ($30) will soon be here to give you smooth, one-handed locking and unlocking action. This innovative design employs magnetic attraction to a steel insert inside the carabiner nose to keep two independent arms locked in place, each of which must be individually depressed before the gate can be opened — and once it is, opposing fields repel the arms to ensure reliable operation.
