Highly visible increment markings and an easy-to-read sliding indicator that stays on the maximum weight registered, make it easy to use. It measures in 2 oz. increments and is accurate to +/- 2 oz, with a range of 8 oz to 8 lbs (2 oz increments). The Trigger Pull Scale is an excellent tool for use when adjusting triggers to ensure accuracy and maintain safe performance.
