Our final product meets all of our primary and secondary criteria - it is retrievable from a distance, fits on preexisting bolts, does not comprise safety equipment, is lightweight, and is easy to use.
No other device exists on the market like this bailing carabiner, and while not everyone needs to use a bailing carabiner for every climb, it can be used as a regular carabiner on a quickdraw as well, making it simple and common sense to carry as part of a climber's kit.
