Just sit it beside the rifle, turn it on, arm it and it captures velocities without interfering with groups. Load work-up, testing at long distance, gathering your dope, even practicing off a barricade. Doesn't matter. Chronographing loads is no longer a separate task, it lets you gather your velocity data while you do some other task. I actually logged data while practicing shooting off a barricade. Just put the LR on a tripod next to the barricade. Menus are well thought out and intuitive. Data is presented in a concise and logical way on a screen that is easy to read.
Tested it with my 6x47L, 223 and 22LR. Functioned flawlessly with each. Had to set it on pistol and trigger off the Doppler for the 22LR, but it worked.

Not bad for 223 ammo loaded on an XL650.
The one thing I don't like is that the interface doesn't tell you to hit the trigger button to arm the unit. You have to arm it before each string by pressing the trigger button. I'm used to looking at the screen to see if a chrono is on and several times I forgot to arm it before the first shot. Wish the display indicated that is wasn't armed instead of looking the same as it does when the unit is armed. There is an LED that changes color, but the screen is where you naturally want to look. Easy enough for them to change with a firmware update.

6x47L worked well in -1C weather.
Tested it against a Magnetospeed V2.

It was pretty windy out. Just before the second shot, the wind flipped the strap over John's APA little bastard muzzle brake and when he fired, it broke the plastic buckle on the MS. So, we had to complete the test with a handyman fix and only compared the two for 5 shots because of this.

The averages had a 3 fps. difference.

If you want to be able to transfer the data to a computer when you're done, remember to put the SD card in before you start testing. Inserting it after you have captured data will wipe out that data. For some reason the LR will save data without the SD card, but it won't let you get it off through the USB link.
Wish I had one of these sooner, it's worth every penny!
