I recently purchased a Garmin Xero to help my coach help me. Like others, was torn between Gamin and the Shotcam - I have certainly found out that the use of the two products together offers very little redundant information. I have found that If you have the environment to set up your practice sessions so that you aren't worried about holding up your squad mates, and then shut down the active display so you don't find yourself worrying more about the read-out than making the shot, the Garmin provides a wealth of accurate information. The common issue that cause "accuracy" concerns is the display of target speed - remember, the Garmin provides AVG. speed, so the bird is slowing and then (hopefully) is shattered. The AVG speed will not be the speed the bird left the house. It also does not consider the angle, so the hard R/L will always read slower than the straight away. It's not intended to verify ATA speed measurements - Keep your radar gun! My overall experience, thus far, is similar to others - So much good information that you need to pick apart the data and work on your corrections in steps. The Garmin will confirm you are on the right track. As others have said it provides a new level training aide for our AIM / Youth shooters. Our club hosts coaching for several local high school teams, and I have offered the use of the Garmin to all three of the coaches. The feedback (100%) is that it allows them to focus 98% on the shooter and not worry about watching the resulting shot, which provides accurate corrections based on Garmin data and the observations of the shooter/student's movements. Bottom line - I have found the unit reliable and beneficial to both shooter and coach in the information it provides -Can the Garmin crossover to Skeet and Sporting or is it mainly for Trap? I’ve used my ShotKam for all.
