Topcon LS-B10 Machine Mounted Laser Receiver 57110

Works great. Can be a little weird setting up but great alternative to a full on topcon system.

The reciever worked ok for 20 miniutes and then erratic. Used 3 times and the same.

Tough, strong magnet, good sound, good visiblity. Leveled a 150 x 150 foot parking lot in no time.

Easy to use and precise. Very good product at a great price. No wireless unit included though, should be clearer on description.

Very bright lights. Only used it on one project so far leveling a place for a building about 18x50. Did well on my excavator stick. Magnets are strong & it doesn’t move. Keep laser to your left and all is good. Also have to set tripod not too low or high if working on a hill so it will read the beam. Checked the level with grade rod after finished & was within 1.5 inches on the whole thing. Not too bad for first use & working on a hill. Strait up & down with teeth straight down is how I had best results on grade check with it. Gotta know it’s gonna read low if stick not strait up & down. Possibly could dig trenches for field lines pretty close to grade& depth once set at right depth if u already have grade marked on top of ground. If set laser to slope, should maintain more accurate slope than just depth of trench. I like it
