This is a great thumb trigger release for archers who like their index finger to be fully enclosed. It's also a good choice for bowhunters, because the jaw closes automatically when the release is cocked, and it comes with a wrist lanyard so you'll never lose the release.
Many people seemed to enjoy the features of the 1st choice, so Carter thought it would only be wise to offer a version with an index finger hole
Thumb trigger release adds an index finger hole to assist with consistent index finger placement and adds the security of an enclosed placement for your peace of mind
