But only as a tool in the pool, and only to make sure I aim in the exact same spot on each and every shot. It's not really needed but would, possibly, help limit the variables. |

Re: Has anyone worked on developing speargun sights?
You are so right. A 5 meter shot is a long way regardless and a sloppy gun or poor load will screw up the shot. I've noticed variance in loading with uneven left or right band pull causing poor grouping. Pneumatics have less an issue with windage but more with ballistic drop due to power loss at depth over 60' and of course distance to the fish. But an optical sight is no good if the gun's shooting all over the place. At least with a laser, you don't have to look down the tube or count on intuition and shooting experience for aiming. There still no guarantees!

Re: Has anyone worked on developing speargun sights?
Here is a laser sight installation on a "Taimen" speargun which is very compact and has a grip mounted switch to turn the laser sight on and off.
Also a short video showing how the switch works. https://youtu.be/-u88efJ_qCM |

Re: Has anyone worked on developing speargun sights?
Cool. Electrical tape and glue. My kind of gun. But where's the battery and how is it swapped out? I question the compression switch too. Water pressure might turn the laser on. Nice inexpensive approach.

Re: Has anyone worked on developing speargun sights?
What you can see is all I know, but being a Russian diver he is most likely spearing in rivers and lakes, so no saltwater (electrically conductive) and no great pressure at depth, maybe 10 meters at most which is 2 atmospheres absolute.

Re: Has anyone worked on developing speargun sights?
Good points. He's making do with what he's got. I think it's a pistol laser adapted to the speargun. But it works and that's the point. Maybe the market for these items is in Russia!

My imaginary view of a laser is one in a plastic or alloy housing with a mechanical/electronic switch in the laser, but the activation to be remote with an adapter. The laser would have a dove tail or rail mount to attach it to a variety of mounting plates or brackets. Remote switch activation would be by cable; mechanical, electrical or hydraulic as all three can bend around corners. |

Re: Has anyone worked on developing speargun sights?
Your laser design would be impressive but expensive to make. The dove tail rail is an extra part but useful for options like a light or reel. Remember, I already manufacture a remote operated, plastic laser with mounting bracket. I'm exhibiting at the Ft. Lauderdale Blue Wild show in April and will test the price point incentive, again. I just hate to make things cheap.

P.S. It occurs to me one could 3D print a rail attachment to screw or clamp on the gun as a mounting bracket for the laser. Then the laser would need waterproofing by applying some sealant in strategic places, the "only" other concern (to put it perhaps somewhat too mildly) is ambient pressure at depth turning on the laser. https://www.newfrog.com/es/product/8...r-sight-215216 Last edited by popgun pete; 12-26-2018 at 02:42 PM.

Re: Has anyone worked on developing speargun sights?
I'm hoping that some of the these adaptations or laser module alterations will work under water and the advertising for speargun lasers explodes. That will make my entry in the market more cost effective. (I.e. Let the competition pay for ads. I still benefit.)
While a laser module that is not designed with water depth and pressure in mind might work once, I doubt the longevity of the tool. A lot of features have to be considered to make the device viable as a working product. And price is the least important concern. Remember, even if its free, if it dosen't work more than once its a waste of time. |

Re: Has anyone worked on developing speargun sights?
Once the momentum is there I am sure underwater sighting lasers will be just another gun option. I can envisage them built into the gun structure such as the grip in an extended finger guard frame just as they are in the kid’s toys. Hollow core handle grip could house all the electronics and battery power and the emitter strategically placed elsewhere, but at a short distance for the electrical connection.
Think of a Biller handgrip, as in their stainless steel tube gun or timber gun, with the laser already built in. When something like this appears lasers will be here to stay. Last edited by popgun pete; 12-27-2018 at 08:28 PM. Reason: added the full length gun |

Re: Has anyone worked on developing speargun sights?
Well now these lasers are coming out of the woodwork! Check this one out.

Here's a shot of laser system mounted to a Wong Gun. Joe

Re: Has anyone worked on developing speargun sights?
We've actually shortened the laser module and added a cowling on the front to protect the glass window. The internals have been improved too. I've send you some photos tomorrow. Joe
