• Manual FLAT PLANE Lasers:

Setup of a manual level laser requires the operator to manually level the unit by using the units' screws and bubble vials.

• Self-Leveling FLAT PLANE Lasers:

Self-leveling lasers automatically find and maintain level within a specified range. Only rough leveling is required upon setup. Self-leveling flat plane lasers use either a Wire Hung Compensator or Electronic Servo Motors.

• Self-Leveling Single and Dual Slope Lasers:

The Single and Dual Slope Lasers find and maintain level within a specified range. You can also dial in a desired slope, turn the unit on and the electronic servo leveling motors automatically maintain that slope. The unit will shut off if the laser is disturbed to prevent elevation errors.

• Cone Laser: Pro Shot L6c 'Cone Slope' Laser for Ball Diamonds  

Allows for one time set up when grading ball diamonds.

• Slope Match Lasers:

Slope Match is tilting a Manual FLAT PLANE Laser or a Self-Leveling FLAT PLANE Laser in the manual mode to achieve a single slope.

How do I achieve a slope with a FLAT PLANE Laser?

Determine the height of the laser at your first bench mark using a Grade Rod Receiver. Place the Grade Rod Receiver at the same height over your second bench mark.

Using a LGA Laser Grade Adapter, one of the tripod legs or if equipped use the raise and lower buttons on the FLAT PLANE laser to tilt the laser beam. Match the laser "on grade" signal from the first bench mark to the second. You now have a consistent slope matched from the first bench mark to the second bench mark.

CAUTION: Unlike the Self-Leveling Single and Dual Slope Lasers mentioned above when slope matching in this way with a FLAT PLANE Laser you are in manual mode and the laser will continue to run even if the unit is disturbed by being bumped, by wind, etc...
