Thanks for replacing the bands on my speargun! The rest of my setup worked great which I got from your shop. Also did the free dive course. Shot my first fish this weekend it was awesome.

Solid fin. Great advice on pairing with foot pocket for the right application. Talk to the team, cannot go wrong.

Better then sliced bread!

If you tie your own bands these are a MUST have! With these long gone is the battle of stretching out your tubing with needle nose pliers or using fancy wishbone tools. Simply slide your wishbone line through the top of the insert, feed it out the side, tie a square knot at the end, apply a tiny bit of dish soap to the band end, push the insert in against a hard surface and VOILÀ! The hardest part is done! These things save you so much time and anguish when making bands. Don’t think about it. Just get some and thank BTS later!

Very Quiet Floatline Breakaway Adapter

These adapters are great to decrease the sound while Spearfishing. The float line clips have a tendency to hit the gun stock and make noise, the adapters prevent this.
Also, I find it is easier to clip the float line and control it away from the gun. I always worry about a fish running and the shooting line wrapping around my hand.
These adapters are well made and tend to last a couple seasons.

Awesome

As a new builder this is awesome - built in line release and safety - it’s plug and play. My first gun I bought a hundred dollar trigger mechanism - and a 20 dollar safety and then messed up installing the line release - this is less money, looks better, and saves me time

BTS AquaFlex Snorkel

Great snorkels

I really enjoy these snorkels. As does my dog but for entirely different reasons. I find them easy, no fuss freedive snorkels. Comfy, easy to clear, and bend out of the way when diving kelp. Mouthpiece fits well and the quick release tab fastener makes it easy to remove from mask straps. My dog finds the soft rubber toothsome, flavorful and seems confused why anyone who left a chew toy in their divebag would be mad about her chomping on it.
