. minute Read

Do you need new scuba fins but don’t want to spend a fortune on them? Sure, you could spend a ton of money on highly advanced fins, which is fine if you are an avid scuba diver.

However, if you just want them for occasional use, there is no point in paying a lot for them. Fairly basic scuba fins for a decent price will do fine for most people.

If you want good fins for a decent price, you might want to take a closer look at the Seac Sub F1 S Fins.

If you need a good pair of fair-priced scuba fins, the Seac Sub F1 S Fins are good options to keep in mind. These fins are mid-range; they are not the cheapest nor the most expensive, and while they work well and do have some good features, they are also not the most advanced scuba fins out there. Considering their price, except for the most advanced divers swimming in demanding waters, the Seac Sub F1 S Fins will work for most people.

Seac F1 S Fins Review: Key Features and Benefits

No Adjustment Straps

One cool feature that these fins have is the no-adjustment strap system. The straps are made of a very durable material, so they are not about to rip. At the same time, they are depth compensating straps, which means that they always apply constant and ideal pressure no matter what depth you are at; they provide a solid and secure fit no matter what the case.



The blades on the Seac Sub F1 S Fins feature special channels which help to channel the water to the tips of these fins, which helps to increase your thrust and minimize the effort required for forwarding motion. The reduction of drag and energy expenditure is important when it comes to scuba fins, so this is something that we do appreciate.


Lightweight and Durable

Something that is neat about the Seacsub F1 S Fins is that they are made with materials that are built to last. These fins are quite durable, but also lightweight at the same time. The fins weigh barely 4 pounds together, which is about as lightweight as you can get. This helps to minimize fatigue and conserve your energy.

Comfort Pockets

The other feature worth mentioning is the comfort pockets. The foot pockets on the Seac Sub F1 S Fins are made to be ergonomically friendly and anatomically correct. They are comfortable to wear, and they help maximize power transfer from the foot pockets to the blades for maximum thrusting power.

Seac Sub F1 S Fins Review: Our Rating

Design: 8

Besides the issue with the straps being too loose for some people, we really like the design of the Seac Sub F1 S Fins.

Functionality: 8

The Seac Sub F1 S Fins quite highly functional. Besides small feet not being secure in the foot pocket, these fins work just fine for most purposes.

Durability: 8

The Seac Sub F1 S Fins are built for durability and they are rugged. While they are not the No. 1 most durable fins on the planet, they will do just fine for occasional use.

Price: 8

In terms of the price, the Seac Sub F1 S Fins do not cost very much. Seeing as they are relatively good fins and we think that the price is more than fair.

What We Like

There are quite a few things that we like about the Seac Sub F1 S Fins. One of these is the fact that they come with self-adjusting straps. These fins are easy to put on and they provide a secure fit no matter what depth you are at.

We also like how the Seac Bub F1 S Fins are so lightweight and it doesn’t require much effort to move forward. These fins are also quite durable, which is impressive considering their low price.

Finally, we like how the Seac Sub F1 S Fins are quite technologically advanced, yet don’t cost all that much.

What We Don’t Like

The fins themselves are a little short, which does limit speed a little bit, but this is not a major issue here.

What some people have mentioned is that the fit is very loose if you have small feet but wearing boots or neoprene socks could help with this.

Other than that, there is not much that we do not like about the Seac Sub F1 S Fins.

Who Should Buy These Fins?

The Seac Sub F1 S Fins are best for people who regularly scuba dive. Now, they are neither the worst nor the best or the most or least expensive option out there. In other words, you probably should not buy these if you will only use them once per year, but also not if you plan on using them every single day.

These are good mid-range fins that come in at a medium price range.
