That's right, the only thing is you have to know what your velocity is roughly. I took my Veterlli out last week, and it took some thinking to capture speeds. It seems with my minimum powder charge (20 gr of 4227,) the velocity is still below the 1700 FPS minimum for the standard reading. I had to click it into it's low speed rangeHow much money are you wasting on ammo shot over a chrono that fails to give you good speed measurement? The Garmin will measure every round fired. That alone will save considerable money.
