Designed to mimic the tail fin of a Humpback Whale, Scubapro Twinjet Fins are a top of the line split fin from Scubapro. There is much disagreement in the diving world about the efficiency and maneuverability of split fins and the Scubapro Twin Jet Fins are no stranger to this controversy.
Scubapro Twinjet fins come in four colors: black, blue, gray, and yellow. They are also available in both open heel and full foot varieties. There actually is a difference between colors. The blue, gray, and yellow fins are slightly positively buoyant while the black fins are slightly negatively buoyant.
Efficiency
Scubapro claims that Scubapro Twinjet Fins have 30% more efficiency than traditional blade fins. The jury is still out on whether this is true or not. It would all seem to depend on who you ask and what kicking style they favor. Many divers claim that Twinjet fins actually require more effort for the same gain while others will agree wholeheartedly with Scubapro's assessment. Why the incredible discrepancy? It seems to have to do with kicking style. Generally, split fins require a diver to modify their standard flutter kick to a shorter stroke. It would seem that by using a regular long flutter kick there is a drop off in efficiency, so you'd only be wise to use Scubapro Twinjet fins if you're willing to modify your kick. Twinjet fins will definitely decrease efficiency for those who like to frog kick.Maneuverability
With its propeller technology there is little doubt that Scubapro Twinjet fins allow for easier maneuverability in the water. Fine adjustments in the water are easier with Twinjet fins and it's for this reason that I'd highly recommend them to photographers and videographers. The only place where Twinjet fins don't excel when it comes to maneuverability is when backfinning. Maybe other divers have had more luck but I find it very difficult to backfin with Twinjet fins.Comfort
Having only tested the open heeled version of the Scubapro Twinjet fins my comments relate exclusively to that design. The foot pocket on this fin is simply the best I've ever had the pleasure of wearing. The open toe allows water to flow freely through the pocket which is a big advantage over many other closed-toe fins. The foot pocket is wide and will accommodate pretty much any bootie while the straps are comfortable and extremely easy to adjust. I've found the straps to be extremely strong and durable and I'd say the only time they may be vulnerable is if they're left unbuckled - it's a good idea to always buckle the straps when you're not using them.Conclusion
Not everyone likes split fins and whether you like Scubapro Twinjet fins will come down to how you feel about split fins. If you're coming from traditional blade fins you'll need to adjust a little but will ultimately find increased efficiency and maneuverability. I'm not terribly fond of the colored versions with their positive buoyancy and definitely prefer the black negatively buoyant version, even if they are a little heavier. If you do like split fins or want to make the switch you won't find many better fins than Scubapro Twinjets.
