Subject: Re: Jet fins with DUI drysuit
Thanks for the additional information. When you say you do not know of any other
fins with those features, does that include the IDI Turtle fins that several
other posters have suggested? It sounds like they are similar to Jet fins, just
with a larger pocket. I don't mind buying a pair to try, but I won't waste my
money if there are known problems with them.

I have some home made spring straps. But the rubber material at the heel of the
boot was sticking out and bunching up in such a way as to make them come loose
so I had to switch back to the rubber straps. What is happening is the hard
rubber sole is getting stuck part way in, and then my toes continue on further
past the tip of the sole. So the sole isn't really lined up with my foot
anymore, and the back end sticks out past my heel. This leaves a gap for the
strap to slip down past my heel. Art Paltz suggested lubricating the fins, but
I've tried that before and it doesn't help much as the bootie soles really are
wider than the fin pockets.

Nick, the reason for the fin rec is as follows: the Scuba Pro jet Extra
Large ( and it must be the extra large, not the large) has a bigger
blade than the rest, and the biggest foot pocket. If that won't fit, I
would ask DUI to change the boots. JJ is an 11 or 12 foot, BTW.

The problem is that when you change fins, you lose the other advantages
of the jet. It is heavy, so holds the feet down well against the dry
suit with no effort, allowing you to add gas to the feet for different
trim needs. The fin is a hard rubber that resists breaking or tearing,
and seems to last indefinitely, and does not change its pliabilty like
plastic does. It is compact enough and well enough controled as to allow
all types of kicks in confined as well as open areas without stirring
the silt. It provides enough thrust to pick up 45 pounds of weight and
swim up with it. You can swim for hours in these fins without chaffing.

Of course , any other fin that does this would be fine, but I do not
know of any. BTW, this fin was first made in a full foot version by
Beuchat, and licensed to all of the others, like US Divers. There must
have ben ten versions of it. It seems that only Scuba Pro had the Extra
Large as a totally different fin, and are still the only ones that have
this part figured out. When diving the big gear, you need the big jet.

I would do whatever it takes to make this fin work , if it were me. For
my own account, I have different set of jets with different length
spring straps for dry and wet. They really need only to cover the last
few inches of your feet to work properly.
