Multi-Purpose Rotating Laser


  • Fast self-leveling - under 5 seconds
  • SmartScan® Technology
  • Horizontal / vertical operation
  • RC-40 remote
  • LS-80 laser detector with rod clamp (GC kits only)
  • Removable lighthouse cover


Set up within 5 degrees of level and push the power button. The RL-VH4 series 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.

Price on enquiry.

The laser can come with a tripod and staff for an additional $99.95. And a “Shockwatch” or “Shocksensor” for an additional $15.

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).
