I'm Labradar guy, love it. It is so handy you will use it just about every time you pull the trigger.
Pictured here while sighting in a Rossi R92 454 Casull SRC-Scout rifle this past week. I have the LBR battery pack and have only charged it once this year, I shoot a lot. If I had unplugged the white cable every time I put it away I would not have had to charge it that one time. I also have the base plate for the bench.
So far the only issue I've had is with a 218 Bee using Trail Boss. I could not get the unit to trigger at any setting and using doppler I would get an error. Velocity is around 1250 with my 50 grain cast bullet and I'm wondering if the Trail Boss kernels blowing out the barrels are messing with the doppler and creating the error. I will eventually get back to that shooting and figure it out but might have to get with LBR and see what they say.
Oh I had some cattle panels laying on my shooting range and it really jacked with it. Moved them over a few feet to one side and problem solved.
I shoot cast bullets of my own designs and it has been most helpful determining the actual BC of the bullet from two velocities from the track info. Use software to calculate it from there but that being done as part of the LBR stats would be most useful.
