BTS Hydro Plastic Fins

30 days
In stock

Our new Hydro Fins offer the best in performace, fit and comfort. 

They shape is wider and taller at the front & top of the foot to reduce pressure on the foot that would cause cramping or discomfort. This shape ensures a better fit for most divers.

The angle between foot-pocket and blade is 22 degrees for more natural ergonomics. The blade angle makes surface kicking and deep diving more efficient and comfortable. The thermo rubber disign of the footpock is three part:

  • 1.) slightly softer compound around the foot to increases comfort, reduce cramping or pressure
  • 2.) slightly stiffer and thicker compound in the base of the footpocket to best transfer energy to the blades
  • 3.) The tendon was made slightly shorter and more flexible to ensure you get the best flex to the blade, allowing it to be loaded with the energy to maximize purpulsion. 

The Hydro Blades are 76cm length and medium compound for the best purpulsion. The base of the blade is thicker to trasfer the energy down the blade & thinner at the tip. They feature water grooves down the blade to guide the water.

Blue Tuna Spearfishing

Please note that Freediving and spearfishing are inherently dangerous sports and should only be undertaken by experienced, well-trained divers. More powerful spearguns must be fired with two hands and a locked elbow to prevent injury from excess recoil. Do not load or unload your speargun out of the water, treat every speargun as if it were loaded. Never point your speargun at anything you do not intend to shoot. Before you begin your dive, be sure to check all your gear. You should never dive alone and your equipment should be serviced regularly. You should always plan your dive and dive your plan. You should discuss safety precautions, your plan, and contingency plans with everyone onboard BEFORE you dive. Communication among divers and operators is imperative. Failure to adhere to these guidelines could potentially result in physical harm or death.  Blue Tuna Spearfishing is not responsible for any loss, damage, harm, or death caused by using any of our products.
