Who uses our lasers? At first it was just the instructors but it's usefulness has been recognized by all divers. Our lasers are being used by almost every marine research project, university and museum in the world that measure living marine animals in their natural habitat.

  

Divers signaling each other can see the beam go past even when their back is turned.

Perfect for instructors, dive masters and buddies to point out something dangerous without getting too close. The lion fish is easy to see, the stone fish is not so easy and the cone shell looks pretty but it is dangerous.

laser measures fish

Most of the marine research organizations around the world are using our Oceanco lasers to measure whale sharks, great whites, manta rays, hammerheads, goliath groupers and other live marine life. They rig two lasers on a bar, spaced a known distance apart, with a camera mounted in the center as seen below..

Many divers are improvising to mount the laser on their spear guns.  Here is a well made rig on a Mares gun.  Many arrangements can be configured with stainless hose clamps available in stores like Home Depot.

For attracting many kinds of marine life.  Seals, otters, sea lions, snakes, and all kinds of fish are attracted to the green laser spot.  They will follow it endlessly, just like a cat will follow the moving dot.. This can be just fun for the diver but also give great opportunity to take pictures of the animals.

Even if people on the boat don't happen to be looking in your direction they might very well see the green spot that will be visible on the structure of the boat, leading them to look for the source of the beam. 

Depending on the condition of the atmosphere at the time your beam might be visible to others at a distance.  The laser is commonly used as a pointer to objects in the sky by people stargazing at night.  They point at the particular planet or group of stars with the laser. While the laser obviously cannot reach the target, the viewers can easily follow the beam in the direction it is pointing.  It will reach low lying clouds and of course be much more visible in foggy or humid conditions, which would be very useful if you need help.
