AdirPro Mounting Bracket and Green Beam Universal Laser Detector

[This review was collected as part of a promotion.] First off you should know this item only works with rotary lasers. That being said it is very compatible with many different lasers from many different manufacturers. It has an up and down arrow that is accompanied with sound indication: fast beep when you're too low and slow when you're too high. I dropped it a few times when I used it on my pool but it survived and no problems. When testing it out, it worked at well over 500 feet so that was a nice surprise. The guidelines state 100 and I've read where others have gotten it to work at 600 as well. Unfortunately being used in sunlight is difficult and I'd like AA batteries instead of 9v. Oh, well, can't have everything. At least the mounting bracket is handy.
