Great Tool
I use it on a backhoe. Works great!

Works well!
I purchased a rotary dual slope laser and was trying to save some money by using the laser detector that came in the kit. I had mounted it on my box blade. That idea worked ok but it was one directional and was talking forever to get the job done so I decided to the Johnson 360 degree laser detector. What a difference that made! I cut my time by more than half. It works wonderful!! I only wish I had purchased it sooner. Very good quality. So, if you’re thinking about large yard leveling this tool is a must.

Ran it with a 'Berger' laser on a 22ton running a vibe plate.
Strong Magnants that held well, enough vibration dampening to prevent shaking or shock damage. Great alternative to the pricier units.
