The Shark Laser with a laser clamp
Mounting the Shark Laser on a spear gun or as doubles on a rig to measure fish is just a matter of using your imagination
Important mounting tip
If you are using two lasers to measure targets please note the way the laser is shown mounted in the clamp to the left. The laser body has a front half holding the laser assembly and a back half holding the battery. The laser is turned on and off by rotating the battery case. If you have the front part in the clamp, you can turn the laser on and off without altering the aiming point of the laser.
Mounted parallel to bar, possible mounting for a spear gun depending on your ingenuity.
Mounted at 90 degrees from bar for rigs such as the one seen above.
