Computes statistics of your progression over time 4. Supports a database of exercises 5. Basic (Simple) format. Enter a Par Time, Delay and the number of reps. Dry Fire Par Timer repeats the exercise. 6. Advanced format. The Advance Format allows you to tune the Par Times and Delay Times to your specific exercise. You can perform the repetitions at a decreasing par time, set an initial delay differently than the other delays and also randomize the delay times to limit anticipation of the beep. *** New in 1.97: Increase the number of reps and you decrease the par time. This will put more focus on the faster par times. 7. Dry Fire supports grouping drills into sets. If your routine is to practice different drills each session, then you can group your drills and recall the set to perform. Dry Fire is available free for a 30 day trial.
