The HP is a full-foot model with
a slightly longer blade than most other fins. The blade features
two flexible channels that allow the fin to alter shape and cup
the water on the downstroke to improve thrust. I have a pair for
pool use, but was frankly sceptical that such a seemingly lightweight
and flexible fin would really cut it in open water. On a trip to
the Red Sea I decided to give them a try. I was on a photographic
trip, using twin cylinders and also carrying two underwater camera
housings. It’s a combination that will create drag however
much you try to streamline your equipment.
The Avantis performed surprisingly well. Using them is quite deceptive
because the lack of resistance as they cut through the water fools
you that you are not really moving. When we hit a current on Ras
Mohammed, the Avantis punched through it. For snorkelling, the HP
fins get you down and back up swiftly and with little effort, giving
you more time underwater. And even two-hour-plus dives produced
no cramps or blisters.
Full-foot fins like the HP are ideally suited to boat diving. For
shore diving, hard-soled boots are usually essential for protection,
making open-heel fins more appropriate. The price ranges from £23.95
up to £35.50, depending on the foot size.
