Scubapro Jet w/ Spring Heel Strap Scuba Diving Fin

Description

The SCUBAPRO JET FIN with Spring Heel Strap is a long-standing standard for power and durability in scuba diving gear. Its rubber blade and robust blade design have made it a trusted choice for tech divers, deep divers, military divers, commercial divers, dive instructors, and recreational divers. The open-heel blade design fits with standard dive boots and is compatible with most open-heel fin pockets.

In underwater conditions, the Jet FIN emphasizes efficiency and reliability. Its vented design decreases drag on the up stroke and enhances thrust on the down stroke, improving propulsion in scuba and diving scenarios. The fin is negatively buoyant, contributing to stable underwater performance at depth. Weighing 5.25 lb (2.38 kg), it uses a stainless steel spring heel strap, with fit options including adjustable rubber heel strap or self-adjusting stainless steel spring heel strap. Available in a wide range of colors to match gear sets.

Frequently Asked Questions

Why are ScubaPro Jet Fins still so popular after 50 years?

The vented rubber design that made the Jet Fin famous is still the reason divers buy it: the vents decrease drag on the upstroke and boost thrust on the downstroke, and the 100% rubber construction is nearly indestructible — ScubaPro talks about a lifetime of use, and plenty of Jet Fins in service are decades old. That is why they remain the standard for technical, military, commercial, and cold-water divers.

What size ScubaPro Jet Fins should I get?

Jet Fins are designed to be worn with dive boots, and ScubaPro's size chart sizes them by boot thickness — for example, a diver with a US men's 9 / EU 42 foot takes a Medium with 3mm boots but a Large with 5mm or drysuit boots. They will feel big on a bare foot; that is by design. Pick your size based on the boots you actually dive, and if you are between sizes, contact us with your foot size and boot type.

Do ScubaPro Jet Fins float or sink?

They sink — ScubaPro officially rates the Jet Fin's buoyancy as negative. Many drysuit and technical divers actually prefer that, because negatively buoyant fins help counteract floaty feet and keep your trim flat. If you want a travel-light fin that floats, look at ScubaPro's GO series or the Seawing Supernova instead.

What do the spring heel straps on Jet Fins do, and how heavy are they?

This version comes with self-adjusting stainless steel spring straps — no buckles to fiddle with or rubber straps to snap; you just pull the heel spring on and it stays put with even tension. Weight is part of the Jet Fin deal: listed weights run from about 5.3 lbs per pair in Medium up to about 7.1 lbs in XL, which is why they are a favorite for local and cold-water diving more than for airline travel.

Thermal Pullover

I purchased this to go along with the matching bottoms bought from Amazon but fulfilled by Divecatalog.com.

Overall, I like the quality of the material, and the material used to line the inside of the suit.

I tried both the L and XL pants, I typically wear a L in pants and shorts purchased from Columbia sportswear, but an XL top. Prior dive suits I’ve had to go with an XL to fit, so with a split top-bottom combination I get to enjoy a more tailored fit.

As far as the pants are concerned, the legs are disproportionately long IMHO.

My one complaint is the legs on the bottoms and sleeves on the top, just end, I would much prefer a sewn cuff for durability and style purposes, and my reason for subtracting one star.

Pay the extra

It may cost a little more but compared to the Scubapro Hydros Cargo Thigh Pocket, but it’s a night and day difference. I haven’t heard a complaint about the S-TEK.

The S-Tek is made from heavy-duty 1000D Cordura, to meet the stresses of the environment and hard use. How does this compare to Scubapro Hydros Cargo Thigh Pocket, people complaining the material ripping apart at the seams/stitching after 20 dives.

Mounting uses a stainless steel bolt snap to the waist harness D-ring and an adjustable strap for the thigh, the Hydros uses a plastic hook and strap.

The S-TEK is the largest of the three, measuring approximately 10” x 5” x 3” which is big enough to fit my iPhone 15 in the SeaLife SportDiver Ultra Underwater Housing.

I’m not sure where Scubapro all went wrong with the Hydros and Ninja pocket, but for the price of shipping, I would only purchase the S-TEK.

Affordable Fins

Purchased these from Amazon, before I learned about DiveCatalog.com, so while I paid more, they were still an affordable option while waiting on the warranty repair of my Scubapro Supernova fins. I wear a size 12 shoe (NIKE & New Balance) and the chart recommends XL which matched the Supernova XL fins, but to me, the pocket felt a bit tight, so I returned them for the 2XL. While you “can” wear them without a bootie, I wear Scubapro Go 3mm socks (3XL) and the still fit fine. The are positive buoyancy, although I don’t think as positive as the Supernova, but I feel better knowing they will float instead of falling to the ocean floor while doffing them prior to getting back on the boat.

Love the Supernova Dive Fins

My new Scubapro Supernova Fins had a small cut on the top of the boot. I asked the dive shop owner what he recommended to fix the boot. He informed me that they were made of monprene and suggested he reach out to the Scubapro Rep prior to trying to fix them with superglue.

I called Scubapro when I got back to the US and they recommended taking it to a dive shop for a warranty repair. Problem is Las Cruces is the nearest dive shop and that's an 11 hour trip. I took it to a dive shop when I flew back to Virginia, but they had to ship it to California, so the process took longer than my stay.

Being modular, I opted to buy a second set of the boot pockets so I don't have to worry about down time in the future should problems arise. Plus I can use Scubapro S-Tek Pro Blade if I want to go with a neutral or negative buoyancy fin.

Objects in your review mirror are smaller than they appear!

Scubapro Hydros Accessory Bungees are smaller than they look, but the Medium size works well for securing my action camera floatie handgrip in place. To set them up, you loop the bungee back through itself to attach to the d-ring fixation point. The center piece then slides down to clamp the accessory.

While they perform great with the grippy, foamy action camera handle, they may be less secure on heavier gear with a slick surface—like my dive light. For that setup, I’d recommend adding a second attachment point on the BCD (for example, using the metal d-rings with a snap hook on a longer lanyard) to help ensure the light doesn’t end up on the ocean floor.
