The lmbr isn’t overly sensitive to ambient light as it is self contained. I have my two mounted in wooden boxes with a plastic barrel guide set a few inches back. Smoke and blast really upsets the reading from too close. Try moving back a foot or two.

Thanks both. Stood further back with bright sunlight I got a spread of 922 - 989 fps. Not great, but close enough for jazz!
