$20. You can see the price increase if you select the glass lens.

The glass flat lens (patent pending USPTO 29387406) available from Pursuit http://freedivingspearfishingg…ens-for-gopro-camera.html fixes the underwater focus/blurry problem caused by the original Gopro curved lens. With the flat lens the GoPro camera can take crisp high definition undewater video. The flat lens is a drop-in replacement for the original GoPro housing curved lens. It has a depth rating of up to 180ft, the same as the Gopro housing. The lens is made of glass set in an anodized aluminum frame.

Video demonstrating effect of the flat underwater lens at the 5 different available settings; R1, R2, R3, R4, and R5. R5 is the most suitable high definition setting for filming underwater and has no vignette effect.

To install the flat lens undo the screws of the black plastic bezel with a precision Phillips screwdriver, remove the bezel and set it aside leaving the screws in it. Take out the curved lens, there's a black gasket that goes between the lens and housing that is usually stuck to the lens and will come out with it. Separate the gasket from the lens and place it back in the housing. Put the flat lens on top of the gasket, no sealant or glue is needed. There's only one way in which the lens can be positioned for the bezel to seat back and the screws align with the screw holes, so there's no worry of assembling incorrectly. When tightening the bezel screws do it in a crisscross pattern to tighten it down evenly. Do not over tighten the bezel screws. Over tightening may compress the rubber gasket too much, making it expand into the field of view of the camera.

I often get asked if it's difficult to install the flat lens in the Gopro housing. What better way to demonstrate how easy it is than by doing it outdoors on a breezy day, on a small uneven work surface, and installing two lenses at once. Adding the risk factor of dropping something in the water for extra tension
Total install time less than 5 minutes. Video was shot with a Gopro in R5 setting, mounted on a head strap.http://www.youtube.com/watch?v=VLODlogMQQY&feature=player_embedded

OK it was somewhat embellished.. But the boats on the weekend are freakin' dangerous!

Fort Lauderdale is very sharky. For some strange reason the sharks tend to stay right at the 100 yard buoy line. They kinda cruise parallel to the shore along that line and don't seem to venture into the bathing area. As soon as you pass the buoys they come in to investigate, sometimes one other times 2 or 3 at a time. Most common are bulls in the 6-8ft range. I have seen a hammerhead on a few occasions and one time a tiger. But that was because I missed the purple warning flag put up by the lifeguards. Whenever you see that you know it's a tiger or a white, they're usually not concerned with bulls unless they're over 10ft long. If you see half eaten sea turtle carcasses at the 1st reef line you better head back fast. I usually ask the lifeguards before I head out. They can see the sharks well because the lifeguard booth is high off the ground and they have binoculars.

I've gone this exact route before. The windsurfing board catches chop too easily, slap slap under the front of the board and too much drag. Avoid wasted time and money, you're better off with a very small kayak. The windsurfing board sold on Craigslist for the same price I bought it..

Jason you're a sling master
Those water conditions are to be envied. -
Palo in Spanish means stick. In colloquial Cuban speech it also means the act of copulation, as in "hechar un palo". So Don Palo is quite an ambitious name <img src= " height="23" srcset="https://spearfishing.world/forum/images/smilies/emojione/1f606@2x.png 2x">

Nice vid, good spearing. Was that the polespear mounted Gopro?

Understandable Aaron. Know that whether you dive or not you're at home here. You are a wealth of knowledge, have great literary skill of your own brand
and have been a great support for me personally. Post your hunting reports instead if you want to share. -
Yes, by cost I meant labor and materials. I don't know much about graphite but epoxy doesn't add buoyancy, on the contrary.
-
Beautiful. I hope it's cost effective. How much weight does it add to the gun?

Weird screaming. I remember my first big AJ and I didn't react like that. Can you imagine the screaming if he shot a nice kingfish or a grouper..

You're welcome.
To clarify; omer Millenium footpockets from different productions vary in stiffness. The stiffness of the tendons affects the overall characteristics of the fin. I make it a point to only select the omer f/p that have the correct moderate tendon stiffness. However the 41-43 size, which is the one that fit nyspear, is always too stiff, so I don't even stock it any more. But I had one pair left and it was the only one that fit nyspear at the time. I thought that combined with a medium soft carbon blade it will make an overall medium fin, but it was still too stiff in this case.

Ah over the polycarbonate lens.. The glass lens is less likely to scratch, you don't have to be so careful if it needs cleaning.

The flat lens fixes the focus problem, I'm not aware of other benefits. The resolution settings are R1, R2, R3, R4, and R5. This video demonstrates the vignette effect in all the settings. R5 is the most suitable high definition setting for filming underwater and has no vignette effect.

BTW there's now a glass flat lens available from Pursuit http://freedivingspearfishingg…ens-for-gopro-camera.html

You're welcome Yonatan, and thanks for the good words.

Monster, do you like the grip on those Pelaj guns? Looks like it doesn't have enough angle and would be tedious to track in all directions.
-
Nice Bill, thanks. I never thought I'd say it but that was too slow
A little faster and zoomed out would've been more informative. -
Good suggestions Xan and Steven.
Mike, the first thing you need to determine is if you're more comfortable hip loading or chest loading.
