Topcon RL-SV2S Dual Grade Laser:


The RL-SV2S is Topcon's hottest and latest rotary laser! This versatile tool is for the contractor or surveyor who wants a tough, dependable instrument that can be employed for flat work, single slope, or dual slope uses. The RL-SV2S can set slopes up to plus or minus 15 degrees with its dual slope function at a range diameter of almost a half a mile (2,600 feet).

Place it on its side and the RL-SV2S can be used to set vertical line alignment with its highly visible red beam, indoors or outdoors. Set it down on its incorporated mount or fasten it to a tripod and the laser quickly self levels itself for use in precise vertical measurements.


The RL-SV2S comes with a full function radio remote, which includes the same controls that the instrument's control panel possesses. The controls have a simple, intuitive configuration and design. Plus, the Topcon RL-SV2S has a long battery life operating as much as a 100 hours on alkaline batteries or 55 hours on the optional rechargeable battery pack.
