Scubapro Seawing Supernova

The Supernova is a two-piece fin: the blade and the foot pocket are molded separately and join with a lock-plate system (a multi-tool is included). The open-heel fin ships pre-assembled and ready to dive, and you can buy an optional full-foot pocket to convert the same blades for warm-water diving without boots — or replacement blades alone. It even comes with a SCUBAPRO boat bag.

Size the foot pocket (XS–XL) with the boots you dive: a US men's 9 / EU 42 takes a Medium with 3–5mm boots but a Large with heavy drysuit boots, per ScubaPro's chart. The blade size follows the pocket automatically — Midi blade for XS–M pockets, Maxi blade for L–XL. Between sizes? Send us your shoe size and boot type and we will confirm.

The Supernova is ScubaPro's performance flagship — built for maximum speed, power, and control, with an auto-adjusting central membrane and winglet tips; it won a Red Dot design award and floats (positive buoyancy, 3.69 lbs per pair). The GO Sport is the lighter, simpler boot-fit travel all-rounder. If you dive often, kick against current, or want the most efficient fin, go Supernova; for an easy-traveling do-everything fin, the GO Sport covers it.

Open-heel fins have an adjustable heel strap and are worn with dive boots, which protect your feet on shore entries and add warmth. Full-foot fins slip on like a shoe against bare skin or a thin sock, and are typically lighter and easier to pack. Most scuba divers choose open-heel fins with boots, while full-foot fins suit warm water, snorkeling, and pool use.

Open-heel fins should be sized around the boots you will actually wear, snug with the strap set so your heel stays seated and your foot does not slide forward in the pocket. Full-foot fins should fit like a firm shoe, with no heel lift, no pinched toes, and no gap that lets water pump in and out. Too loose causes heel blisters and lost fins in current, and too tight causes foot cramps.

Choose your boots first and size open-heel fins around them, because sole thickness changes the foot-pocket size you need. A thin warm-water boot and a thick cold-water boot with a rugged sole can easily be a fin size apart. If you already own fins, bring them along when you buy boots so you can check the combination.

Spring straps replace the adjustable rubber strap with a stainless spring that stretches on and off, so there is nothing to buckle with cold or gloved hands and no rubber strap to perish and snap mid-dive. They hold constant tension, which many divers find more comfortable and consistent. They are sized rather than adjustable, so match the length to your foot pocket and the boots you dive.

For travel, length and weight matter most, so shorter blades and travel-specific open-heel or full-foot models pack more easily and save baggage allowance. Some fins have removable blades or compact foot pockets designed for luggage. Pack fins along the outside walls of your bag, where they also act as protection for softer gear.

Paddle fins use a solid blade that transfers power directly, which many divers prefer for precision, control in current, and non-flutter kicks such as the frog kick. Split fins have a slit down the blade that lets water pass through, which generally makes flutter kicking easier on the legs but gives up some control and works less well with other kick styles. Neither is inherently better, so let your kick style, leg strength, and conditions decide, and try both if you get the chance.

Rinse them in fresh water after each dive day, paying attention to buckles, springs, and strap channels where salt collects, and dry them out of direct sunlight. Store them flat or hanging from the foot pocket rather than standing on the blade tips, which can take a permanent bend. Check straps, buckles, and any screws before every trip, since a failed buckle is the most common fin problem.

ScubaPro lists the Supernova at 3.69 lbs per pair with positive buoyancy, so they float rather than sink. That is light for a full-performance fin — the Supernova is the flagship of the Seawing line and a Red Dot design award winner. If you specifically want a sinking fin for trim in a drysuit, the Jet Fin is the one to look at instead.

The open-heel version ships pre-assembled and ready to dive, with the multi-tool for the lock-plate system and a SCUBAPRO boat bag included. Because the fin is a two-piece design, you can later buy an optional full-foot pocket to convert the same blades for warm-water diving without boots, or replacement blades on their own.

Completely different tools. The Supernova is the performance flagship — a modular two-piece fin with an auto-adjusting central membrane and winglet tips, built for speed and efficiency, floating at 3.69 lbs per pair. The Jet Fin is a vented rubber fin that has been the technical, military and cold-water standard for 50 years: nearly indestructible, negatively buoyant, and 5.3–7.1 lbs per pair. Go Supernova for efficient propulsion and easier travel, Jet Fin for durability and sinking trim.

The Seawing Supernova open-heel foot pocket uses a marine-grade bungee heel strap. The marine-grade bungee strap stretches on and off over a dive boot. The strap is part of the foot pocket, which separates from the blade through the Socket-Lock Connecting System for easy packing.

SCUBAPRO lists the Seawing Supernova at 21.97 in overall length and 8.66 in overall width, with a foot pocket 9.45 in long and 3.15 in wide. Because the blade and foot pocket separate at the Socket-Lock connection, the two-piece design makes the fins easy to transport.

The Seawing Supernova is offered in Black and White, each in five foot pocket sizes: XS, S, M, L and XL. Black sizes run item numbers 25.505.100 through 25.505.500 and White sizes run 25.506.100 through 25.506.500. Size the foot pocket around the dive boots you actually wear, since sole thickness changes the size you need.

Yes. The Seawing Supernova is compatible with SCUBAPRO's colored Scuba Skegs. The fin is also compatible with the optional Modular Fin System full-foot pocket, sold separately, so the same blades can be converted for warm-water diving without boots.
