Hey guys, long time reader first time poster. I am considering purchasing a laser setup and thought that the magnetic receiver would be kind of handy and just wanted to see if anyone here has any experience good or bad with them. I am leaning towards a Topcon system over a Spectra because of the 5 year warranty. I called on a Topcon system today and the salesman wanted to sell me a higher end receiver (LS-B100) because he says they have troubles with LS-B10 falling off of machines. My thoughts are if they are that bad then I can make a different more secure mount for a lot less than jumping up to the next model. Or I can get off my butt and check it with the stick. I'll mainly be using it on my 20Klb.excavator but would probably at least try it on our dozer I'm sure. I mostly just "play in the dirt" on the weekends and on my days off. I see using it for building pads and footings and also for some drain tile work possibly around the farm Thanks for the help and great forum.
