channeled and reduce fatigue on the diver's shins. I often suffer from cramp when wearing "conventional" fins that do not have this feature.
The acceleration is very quick and the kick action can be modified to suit the diver, I now use a flutter kick, which propels me as well as a full leg kick. The twin blades are responsible for this, as they create a hydrofoil effect and maximise the amount of thrust for every fin kick. Buddies have complained that I'm too quick when wearing these, but, as ever, YMMV.

The straps that came with the fins were replaced quickly with bungee cord, which allows me to get them on and off very easily and quickly. I broke a strap clip on the second day of diving and decided not to buy new ones because of the price of replacements. Scubapro updated the clips since I bought these fins and, to be quite ...
Advantages: comfortable to wear Disadvantages: not as much propulsion as other types
These fins i found after several uses i had fewer leg cramps when using these than i do my other fins and i found as a result my air consumpption was less.
But these dives were mainly conducted in calm conditions with little or no current running, such as while training in Capernwray.
In a current i found that i was less comfortable and was not making progress as i would have liked, when i used the fins diving the thistlegorm i found i caused less of a silt up although i didnt do as much of a prenetration as would have been usual for my familiarity on the wreck. This was due to a slight current i encountered outside the wreck which caused a necessary shortening of the dive, because i was breathing harder due to the having to fin harder to keep with my buddy.
Over all the fins i would recomend in the likes of a quarry or lake but not ...

Advantages: Very little effort required underwater, flexible Disadvantages: Not cheap, not the best for long surface swims
My Mares Volo Power fins are among the favourite items of my dive kit. While pricey, they do a very good job, and make finning underwater incredibly easy. One of the few drawbacks is I find they're not as good for surface swims, particularly against current. They are longer than many standard fins, which takes some getting used to, and it's something to be aware of when you're near fragile coral reef. However, they're also ultra-flexible, and I usually find I can get back into the boat while still wearing them.
Initially I found the quick-release catch at the side to be rather cumbersome - the lock-unlock mechanism isn't very easy with gloves on. To be honest, I've now taken to closing and not locking them, and they've never opened up while I'm in the water.
When these fins first appeared on the market they were pretty expensive ...
