I received an e-mail asking how I am able to pull the trigger on my crossbow without the use of my fingers. It's very simple, I use a BMF Activator that I purchased at cabelas. This is one of the best trigger activators on the market, and I would not hesitate to recommend one.
I also plan on putting one on my shotgun when the time comes! It's nice when an item is designed for everyone, even hunters with quadriplegia!
