They'll catch a lot of fishermen.

When you travel, airlines usually will give you a cardboard box for these fins
if they don't fit in luggage. I'll never use anything but Picasso BT fins until
they make a better pair for general freediving. You don't want carbon blades
unless you're competing. The regular blades are flexible and strong. I've been
wearing my Picasso BT fins since 1999. I haven't had to replace blades or foot
pockets yet. One of my former students who is now world class material has had
his BT fins for maybe (I'm guessing) 3 years? He hasn't replaced blades or
pockets. Trust me. Our fins get used FAR harder than yours will and they
haven't crapped out yet. The same can't be said of my students who've purchased
Omer, Cressi & Sporasub. They will definitely become your favorite fin. When I
switch to Scuba Pro Jets for DIR training, wrecks & caves, if there is ever a
current, using Jets is like showing up for an orgy with erectile dysfunction
without viagara -- no real thrust -- compared to the performance you'll get
from BT fins. But, if you are doing frog kicks all day, or penetrating, stick
with fins like Scuba Pro Jets to allow you to have the right fins for all the
kicks you can do. If you're cruising open water and want great propulsion in
currents & want freediving fins the BT's are the best.
