The Topcon LS-80X laser receiver is able to allow you to have a longer range when using a red beam rotary laser. The unit can be adjusted for either a fine or course band, which will help improve the accuracy. It has an audible notice for the height, to make sure it is adjusted properly. The Newly improved LS-80X has a rear mounted speaker with a louder setting for a louder audible tone on noisy jobsites where the audible tone is hard to hear. With a rating of IP-66, the Topcon LS-80X laser receiver is protected against dust and water. The LS-80X provides exactly the information needed at the leveling pole, including alerts for situations involving heights, out-of-range locations, and low batteries. And it's job site ready - rugged, water and dust resistant, and usable with most conventional rotating lasers.
