I also got mine out to the range today.
The short version: if you're a handloader or long range rifle shooter THIS IS THE BEST THING SINCE SLICED BREAD!
The long version...
Setup:
While I was setting up, I was watching a guy a few benches down setting up a Caldwell chronograph in front of the line. I pulled the Garmin out of my bag, unfolded the little tripod and set it on the bench... ready. I watched the other guy make multiple trips out to his chronograph... set up the tripod, hang a weight bag (it was windy), mount the chronograph, line it up, carry his tablet out to connect to the tripod, etc.... all to be repeated when he tore down for the day.
I started with some (29) rounds out of one my ARs, since I wanted to verify my zero, and test the Garmin before doing anything serious. It captured every round fired, and I was able to shoot on my target and steel at several different ranges and angles, something that wouldn't have been possible with my Caldwell.
Next up was a series of handloads (25) out of my 6.5CM for load development. 4 different loads, and some factory Hornady for comparison.
Again, the Garmin captured every shot. Note that both the 5.56 and 6.5 were suppressed. I don't have a direct comparison, as the last time I did any chrono work with the Hornady 6.5 factory ammo was 2 years ago, under different conditions. That said, numbers are definitely in the ballpark... Hornady says 2710fps for their factory loads, I got an average of 2698fps.
Next up was handgun. I had my new to me Uberti Schofield out for the first time with some "cowboy" (light) .45 Colt loads.
Once again, the Garmin picked up every shot. I had a shooter on the adjacent bench to the right (.308), and two benches down to my left (various rifles), and the Garmin never picked up their shots.
Once I was done, I folded the little tripod and tossed it in my bag.
I have not yet tried the phone/app connection, but you can view your session history on the device and get some basic data from each session (ave vel, std dev, high/low, etc). Next time out, I'll give the app a try.
This thing is fantastic. It's not cheap, but it's worth it. What you basically have is a chronograph that's not much bigger than two (50rnd) boxes of .22LR ammo, that you can have up and running in 10-20 seconds without leaving the bench. In the past, my chronograph only went to the range a couple times a year because of all the hassle involved. Now, the Garmin will probably go to the range nearly EVERY trip. There's no reason not to, and as a handloader and rifle shooter, having that data available should pay big dividends down the road.
