You'll have to ask yourself what do you intend to do with the laser. Indoor? Outdoor? Grading? Metal studs and Drywall? Cabinetry? Interior finish work?
I install dry-erase boards,pushpin boards,acoustical panels at a large automotive mfg tech center in Warren MI. We use lasers every single day. Currently I am rocking the
Dewalt 360 . I have a new co-worker that has the
Milwaukee 360, but I honestly have not had any serious time to compare the 2. I do know the Milwaukee has a fine adjust built-in for vertical lines, a horizontal fine adjust is available with a 2nd(optional) bracket. Most of us, all started with the Dewalt crossbeam, 3 AA battery ,under $200 lasers. In two years I have moved to the cross beam 12volt and/or the 12V 360. For some of the layouts we do it just made more sense. Some of the lower priced lasers,(like the $150 Bosch) we experienced accuracy problems over 12 to 15 feet. I do not recommend those. We also have 4 guys now using the
Heupar 503CG laser. They have been reliable,as accurate as the DWs or Milwaukees. They have a proprietary battery,which is not as big or long lasting as the DW/Milwaukee but the Heupar can be charged/plugged into the wall via a USB-C cable .It can also be powered with a portable power bank ,and likely run for days. Heupar also has a couple different
brackets/tripods that are handy based upon your needs. I have not ran any of the lasers outdoors with an(optional) receiver ,so I cannot comment on that aspect of any of the lasers. Also have crew members using
Spectra and
Hilti PM-30 and a
Hilti PM-40. Those have a $ignificant increase in price. Also new to the market,a co-worker is looking at this,seems to have a very slight accuracy advantage over some of the others
