Value, advanced technology, proven durability, and four package choices to fit the way you work. Only Topcon has it!

Superiority that's easy to see – indoors or out

Topcon's world's first ultra-visible GreenBeam® technology quadruples beam brightness so you never lose valuable time hunting for the beam in direct sunlight or on the scan target.

Why green?

Simply, Topcon's GreenBeam is brighter - up to four times brighter than conventional beams. As the chart shows, your eye sees certain wavelengths of light better than others, with the mid-500 nanometer range being the most visible. That's why Topcon developed the GreenBeam®. You can see the GreenBeam® anywhere under any conditions. Set the laser up for best coverage without worrying about having to work in shaded areas or near windows.


Set up within 5 degrees of level and push the power button. The RL-VH4 searies features fast self-leveling (under 5 seconds) so it will be spinning and ready to go to work when you are. There's even an HI alert / auto shut down assuring there's no costly re-work should the laser be bumped or disturbed.


Topcon's SmartScan lets you draw a line of focused laser light on any surface, to any length you need. And it stays there as long as you need, automatically, until you release it using the target.

Vertical Alignment

Use the 90 degree plumb beam to easily square walls and align wall track. Simply place the optional vertical target on your line, place the RL-VH4DR at the other end, and use the manual slope buttons, or included RC-40 Remote to center the beam on the target.

RC-40 remote 

RC-40 provides complete control of your RL-VH4 laser up to 300' (100m) away. It also features two-way communication providing HI alerts and laser battery power confirmation from the remote.

LS-80 Laser Sensor (standard with GC kits)

Perfect when you're using your RL-VH4 series to set footers or check grade the LS-80 features an audible on-grade alarm, 11 levels of on-grade indication, laser power indicator, and HI alert, all displayed on a high contrast LCD. The LS-80 also comes with Topcon's Sensor Holder 6, perfect for attaching the sensor securely to just about any grade rod, square or round.

Removable Lighthouse Guard

Every RL-VH4 series laser features a removable lighthouse guard. Simply push the release button and tilt the guard back for unobstructed operation. Snap it back in place for complete protection of the rotating head in harsh or potentially damaging environments.

The power to work the way you want to work…

The RL-VH4 series offers three power options for convenience and flexibility: alkaline (standard), rechargeable (optional), and AC run/charge (optional).

The RL-VH4G provides up to twice as many hours of operation from one set of alkaline batteries than other lasers.

Topcon's RL-VH4 Series – up to four-times more visible with twice the operating time... it's an unbeatable combination. Topcon. It's time.
