The L-708 Standard and L-708LD Long Distance Bore Lasers are designed with coarse and fine adjustment capabilities that expand the range of angular beam adjustment to make setup easier and faster. Both lasers are designed to work with our A-514 Adjustable, Self-Centering Bore Adapters so the laser can be mounted directly in a bore, vastly simplifying the setup.
The L-708LD is a long distance version of the L-708 for applications up to 200 feet (61 m). The L-708 can be used out to 100 feet (30.5 m).
Both lasers have a mounting surface with a 1.2498 in. (31.74 mm) OD. The laser beam is centered to the mounting OD to within .0004 in.(0.010 mm).
High-pitch adjustment knobs adjust the pointing control of the laser beam down to .000007 in./ft. (0.0006 mm/m), so the vertical or horizontal angle of the laser beam can be adjusted to find the center of the reference bore target.
Both lasers will operate for up to 8 hours on a battery pack with standard, replaceable 9-volt cells. An AC adapter is provided for continuous operation.
