Great...So Far.
I just received it a couple weeks ago, so only used it twice. Bison did a great job of getting it to me quickly and without any problems. My first impression of this unit is the size, it is really small, smaller that a deck of playing cards. I purchased this one to replace a Magneto-speed as it was inconvenient to run multiple rifles and affected the point of impact, so I had to dedicate time and ammo to check my velocities.
This unit works great, very easy to figure out, even without reading the directions...though I will at some point, as there are some advanced features that I have not explored yet.
The first time I took it to the range I screwed on the small tripod, set it under the rifle bipod and started shooting. That is, it, so easy! Nothing touches your gun, so I ran velocities all day on every shot, so the data is more significant. On one rifle I attached my magneto-speed to validate the new Garmin, the readings were nearly identical, all within 5fps.
This last weekend I was in an Advance Precision Rifle class where we were setting-up ballistics applications, so getting the correct velocity is crucial. The school has an old-fashioned Cadwell optical unit, we also set-up my Garmin and ran them side-by-side. We found this unit far more accurate, as the velocities were more consistent, the optical unit was within a few FPS on most shots but varied up to 40 fps on some.
This thing is a dream; easy to transport, easy to use and very accurate.
