I have not found mine to be so sensitive to aiming that it required a more precise aiming aid than the V-notch in the top. Since i started using the phone app to control it, it doesn't get touched once I power it up. It doesn't move around on the concrete shooting tables at the local range. The 10 pound, gimballed mounting plate that I made for it doesn't hurt either.
I did have an interesting problem however. When using it with a Lead Sled DFT, that has that large pan on the bottom to holds the weights. It must reflect the shock wave or something which seems to confuse the LR to where I can't get reliable triggers with loud rifles. Take the lead sled away, switch to a front rest and rear bag and all else being equal, it triggers fine.
When I first got my LR, I did make a baffle out of an 8x16x2 concrete paver with 3/8" dense rubber pads glued to the sides, mounted in a holder to keep it upright, That was a
band-aid for unreliable triggers when using rifle brakes with or without the Lead Sled. Didn't matter whether it was even with, in front of or behind the muzzle. It was very maddening early on. So much so that I was prepared to sell it, even for a loss, to the highest bidder! Big time buyer's remorse! Another member at the club was an early adopter also. He used his for load development on a different range, out in the open and he didn't have any problem with reliable triggers. Then, the company came out with a firmware update for it without much of a change log saying what it corrected. After I installed the update, the trigger problem vanished. Keep in mind that this was before affordable, external, aftermarket inertial triggers had come out. Our local range's
Rock of Gibraltar concrete shooting tables sit on a concrete pad with a thick plywood ceiling about 8 ft over the shooting positions and it maker for a
hard sound environment. Open on the front, sides and back but really reflective up and down.
Thank goodness the company resolved that issue with a firmware update or I would not have grown to really like mine for all the reasons already covered.
