Leica Geosystems AR864435

Probably one of the best lasers on the market can see a line over 100 feet in daylight

excelent... powerful light

Klare, detailierte Linien auch am hellen Tage eindeutig sichtbar. Gut mich für Leica entschieden zu haben.

Très très bon produit ...

I'm renovating my home and the simians who built it wouldn't know a straight line if they were clubbed to death with a level. The house has also settled over the decades, so nothing is square even in the off chance it was once. This thing was worth every penny! Since I can't trust anything in the house to be square or plumb, I have this. I don't need to hold it like I do a level. I can set it up on my old camera tripod (the foot for my tripod and the laser both use a standard mounting screw), or I can just set it on a bucket, or I can use the neat clamp that came with it. It blinks to let you know if it's in lock mode (the mode used to prevent damage during transit, but it prevents the laser from "floating" and finding level) so you don't accidentally go off a line that isn't true. The green line is quite visible (more so than red lines I think), and suitable for anything indoors, and can be used outdoors as well on cloudy days (or before sunrise if you're one of "those" people). The line also doesn't become much thicker as the distance increases. It goes from roughly 1/8" at point blank to about 1/4" at 50' and if you make your mark in the center of the laser line it's fine regardless. It comes with a rechargeable battery pack (and charger), and can also accept standard batteries, and you have quite a bit of time from when it warns of low power till it actually turns off. You can also use it while plugged in to the charger. I've never been in a situation where I couldn't use it due to power. The clamp it comes with is great because you can clamp on to a 2by or anything thinner, it allows rotation, doesn't block the vertical axis laser dot, and the clamp is also magnetic. The clamp itself can be mounted to a tripod as well. The two parts of the clamp are held together by the magnet and the magnet is strong (be careful to not let it pinch you; it hurts lol). The magnet also allows for attaching to anything vertical and iron like a steel stud. There is a small gear that allows for a small analog adjustment vertically of about 3". The only two complaints I have are that the little rubberized feet on the clamp's jaws are NOT glued into place and just slide off and become lost. You will not be able to get replacements. I've tried. Their customer service is difficult to get a response from and they only offered me a full clamp at slightly less than retail cost. :/ The other complaint is minor. The laser comes with a plastic "targeting plate" or something that's supposed to make the laser higher contrast and let you adjust to a specific height at a distance. It's worthless for that. Just make your mark with a felt marker and do your best while squinting. If you have assistance to tell your higher/lower/left/right that helps a lot. Bit of advice, do NOT attach or set the laser/clamp on anything that can move or vibrate, even slightly. I was working on shimming a wall with panels to correct it being a bit out of plum. When I was done I doublechecked my work and found that the laser had shifted due to the hammering. Also keep other workers away from the level. They won't notice when they bump it or tell you if they do :( Despite these somewhat minor issues, this thing has been a lifesaver. I wish I'd gotten it sooner and just skipped buying bubble levels. I don't even use them anymore except to put up to my laser line for fast straight marking!
