TP-L4GV
Unbeatable visibility, patented scanning technology, simple operation. Once you see it, the TP-L4GV will be the only pipe laser you'll use.
TP-L4GV features include:
- GreenBeam® technology
- SmartLine® to make second day setup and alignment automatic.
- Automatic line centering and grade zeroing.
- World's Only 3-way beam for fast, accurate setups.
- Bright, easy-to-read rear display.
- World's Best long-range spot quality.
- RC-200 radio remote for complete control of all TP-L4GV functions from up to 660 feet away.
- All metal, waterproof housing so you know it'll survive even under the toughest conditions.
Topcon's innovative Green Beam® technology gives you the advantage of a beam that's four times brighter than conventional beams. That means you never lose track of it - even in direct sunlight! With the TP-L4GV Green Beam® setups are faster and easier than ever before.
The TP-L4GV also has SmartLine® for fast, simple alignment. Just set the target at the far end of the last section of pipe and push the alignment button on the RC-200 remote. The beam automatically centers on the target for perfect alignment every time. You can even use SmartLine® for quick above ground setups!
