I'm looking to purchase a pipe laser. I've narrowed it down to the Topcon. What is your guys opinion on the red compared to the green beam? I'm trying figure out what model to purchase.
I just have the feeling that your sales rep had some green lasers that he wanted to sell,it just goes against my reasoning that the green laser draws more current than the red one,and twice as much?It would not be hard to find out these days as you can get the specs online for a lot of devices.I used to buy from NTE electronics,an aftermarket supplier and they publish specs for just about everything that they sell and even if you cannot cross the mfg part number you can usually find a replacement in their inventory once you know the specs.I have found that Spectra-Physics makes pretty good stuff,at least it has been the most popular in my area.One feature that I liked was the self leveling feature when using the rotary beam to hold your grade while digging a cellar hole for example because when setting the tripod up on frost and the sun comes up many times a regular laser just keeps spinning but the self leveling laser will stop spinning so you know that you have to check it before it is too late.Ron GWe have a spectra 711. We do a lot of live mainline sewer install and all that raw sewage flowing past it has not killed it yet. When we bought it we talked about getting a green beam but the sales rep talked us out of it. He said the way a green beam works requires it to burn a lot more energy for the green light. Expect half the life from the green diode and even less then half the run time on the batteries. Also for us the only advantage was light visibility when the sun was shining down on your beam. When working in a 14' deep trench in a trench box the sun realy is not a problem.
