For years I used a Pact Model 1, while it still works it is aging. Pact does not offer any replacement parts for this model. I begun to look for a replacement. Last spring, I chose the Lab Radar and have used it extensively with handgun, rifle, Contender and Encore pistols from 22 caliber to 50 B&M AK. No skyscreens to align in front of you, no more lighting or weather concerns. I set the Radar up on a tripod to the right of gun of choice align to the target and begin. You can set your displayed distance for velocity 10, 25, 50, 75, 100 yards as an example. While this is the displayed distance for quick visual reference it tracks the bullet and logs this in a CSV file. Smaller caliber bullets 22 ? 284 track to ~75 yards, larger caliber have tracked out to 110 yards. It provides the shot string averages, SD, ES. I am very happy with it.
