Training in a dry-fire mode can do absolutely no disservice to a shooter. Generally speaking, it takes 2-3 live practice sessions for an athlete to get used to blowback/recoil after 2-3 months of just dry-fire practice.
Given the longstanding experience accumulated with the collaboration of shooters and coaches (Shooting Team of USSR and Russian Federation), we recommend:
Top-class shooters to train with the SCATT system for approximately 70-80% of overall training time in regards to the routine training period and up to 30-50% during the contest season.
There was a case of an athlete using the training system in dry-fire mode alone for three months leading up to a forthcoming Russian Championship. He then had only 5 live-fire practice sessions and subsequently won the gold medal, setting a new Russian record in the process.
Beginners to train only with the SCATT training system. The later a beginner gets his/her hands on live-fire, the better. Weapon’s recoil and shot sound slow down the learning process two or even three-fold.
Shooters that have a bias against training systems can use SCATT trainers for the sole purpose of error diagnosis. The system can also help them explore new shooting positions and natural points of aim providing an immediate feedback on the efficiency.
