Follow up with extended inclement weather use
1. Took it to Core/Altus Shooting solutions for field testing in late July. Temp 95 deg F, humidity 83%, sunny, DA 1500,
1.a. Left it out on the table from 9AM - Noon, used it to verify known distance targets. Distances were spot on and quick to return distance, inclination, and windage/elevation out to 940 yards.
1.b. No heat soak issues. Turned on instantly, LED info bright and legible without washout.
2. Today is wet and rainy from Tropical Storm Marco, so no range day but got a chance to play around with the LRF in the back yard.
2.a. Able to range to 196 yards through moderate showers on first lase. Rain intensity ~5/10 (IMHO scale).
2.b. Able to range to 196 yards through mist in-between rain showers on first lase.
2.c. Able to range from 38 yards (tree leaves) to 196 yards (trees at a distance through a ~2'x3' opening in the foliage). First lase hits.
Overall assessment: the Bushnell Nitro 1800 is a high value LRF with capabilities to lase standard IPSC and 16" steel gongs out to 940 yards. In my testing it worked well in hot environments with good LRF accuracy in rain, mist, and through foliage.
What I'd like to find out: Performance in cold and snowy environments, maximum practical distance for reflective and non-reflective targets, long term durability, performance during match/hunting conditions (ie: is it faster to lase and get elevation/wind data and verbalize to shooter vs. using traditional spotter/shooter communication or other integrated LRF/DOPE systems)
YMMV, happy shooting.
A few notes I'll add to your observations - In my experience, Altus can be rough on LRFs - not sure if it's just due to brightness, UV, color of the berms, or what. Your experience with the Nitro matches up with mine on performance, though.
For usable distance, I was getting consistent hits on steel at Alabama Precision at 1250 or so (Can't remember for sure), and that's the furthest steel I have been able to try. I'm hopefully going to be able to remember to try it out at Arena when I am there for the AG Cup in October. I've also been able to consistently lase buildings at 1300+ and a semi-glossy water tower at 2k.
For match/hunting conditions, I think the real money is going to be pairing the 1800 with a Kestrel 5700 and HUD. Using that combo resulted in data appearing on the HUD within ~3 seconds of lasing the target without even having to touch my Kestrel - it was hanging off my belt in a AG Kestrel pocket.
