When I dive with Force Fins will I burn less air?

  • "I was diving with a couple of friends. I was wearing a pair of Foil Force and I didn't realize how fast I was traveling. When I turned around, my friends were way off in the distance. They were surfacing because they were running low on air trying to keep up with me. So I had to surface early, with plenty of air left."
    -Mike Dahan, Owner of Channel Islands Scuba

  • I like power, will Force Fins work for me?
  • "My favorite fins are the Tan Delta Extra Force Fins because they're stiff. You don't have to kick them as frequently. Each kick sends you gliding for about 5-6 feet. They provide lots of power."
    -Zack Silveria, owner of Tracy Skindiving School

  • "I like the performance level of the Extra Force. I'm a professional diver/instructor and they meet up to my varied needs and types of requirements. I can really count on them when I need extra power in strenuous situations."
    -Darin Duffin, owner of Midwest Aquatics

  • "I use different Force Fins for different reasons. Extra Force are probably my favorite. I really like them for general SCUBA diving because they have a lot of umph. I kick everyone's butts when I'm wearing the Extras."
    Jonathon Bird, Emmy Award-winning underwater cinematographer and producer

    How will Force Fins work in a current?

  • "I was diving in the Bahamas, with three special forces guys, all half my age and in much better physical condition. They were teasing me about my Force Fins. I noticed that there was a powerful current running, and I knew that with their "traditional" fins they would not be able to sustain the kick against it. So I challenged all three of them to a race, up the current 100 yards and back to the boat. Not only did I beat them, but I was back to the boat before two of them even made the first hundred yards."
    -Captain Tom Bryan, Owner of Action Aquatics

  • "I was training some new divers. Two of them strayed off the line, and got caught in a current. They were trying to swim back, but the current was just too strong for them. Kicking with the current, I easily met up with them.... Kicking upcurrent with my Extra Force Fins, I was able to tow them back to the line."
    -Darin Duffin, owner of Midwest Aquatics

    How do Force Fins compare to other fins?
  • "I did a comparison swim with the Foil Force and another split brand. I swam for 500' at 15' of depth. With your fin I went farther, faster and used less air wearing twin 72's and a wetsuit."
    -Hal Watts, Owner of Hal Watts 40 Fathom Grotto

    Are Force Fins good for underwater photography?
  • "I originally became interested in Force Fins because I thought it would help keep silt from forming which benefits my underwater photography. The initial reaction from my staff and others was curious humor - they thought that Force Fins were funny-looking. After 3 dives I was convinced that they were the best fin I had ever used. On many occasions I have shocked others with the acceleration they create. Now they are my best selling fin and many of my staff have converted to Force Fins!"
    -Steve Mussman, Owner of Sea Lab

  • "For videography I prefer the Pro Force because I can back up in them. They are the only model of fins that you can back up and pivot in your own axis. They're the only 'full control' fin that I know of."
    -Mark Hannafin, Owner of Family Scuba

  • "As an underwater photographer and now videographer these fins are the best thing an amphibious picture maker could want. ...If only they all knew the power of Force Fins."
    Dave Bryant, Underwater Videographer

    Can you use alternate kicks such as , and frog kick with Force Fins?
  • I really like the Tan Delta Excellerating Force Fins because they are real attention grabbers and they are great for sculling."
    -Dave Leander,Owner of Great Lakes Divecenter

    I have bad knees. How will Force Fins work for me?
  • "I have bad knees. I tried Force Fins for the first time in 1996. After a weekend of teaching, I was surprised to find that my knees didn't hurt on Monday, Tuesday or Wednesday. I've been diving Force Fins since, and I honestly believe that kicking Force Fins helped recondition and strengthen my knees. I haven't had to take a cordizone shot since that first weekend kicking Force Fins..."
    -Harry Gunther, owner of Crawdaddy's Scuba

    When Kicking Force Fins, will I travel fast?
  • "Dive Masters in Costa Rica couldn't keep up with me in my Force Fins trying to chase manta rays with my video camera."
    -Ron Johns, owner of Heartland SCUBA Center

  • "I was diving with a couple of friends. I was wearing a pair of Foil Force and I didn't realize how fast I was traveling. When I turned around, my friends were way off in the distance. They were surfacing because they were running low on air trying to keep up with me. So, I had to surface early, with plenty of air left."

    -Captain Tom Bryan, Owner of Action Aquatics

    Are Force Fins easy to kick?
  • "My favorites are the Foil Force because they are easy on the surface, so for training they can't be beat. You don't have to spend time teaching students how to kick, and they're great underwater too."
    -Mark Hannafin, Owner of Family Scuba Center

    Are Force Fins maneuverable?
  • For videography I prefer the Pro Force because I can back up in them. They are the only model of fins that you can back up and pivot in your own axis. They're the only 'full control' fin that I know of."
    -Mark Hannafin, Owner of Family Scuba Center

  • "We book more dive travel than any other on the East Coast of the United States. We're sensitive to the impact our customers have on the delicate marine environment. We were diving in Bonaire. Another group of divers, all wearing Force Fins dropped down not far from us. They appeared to be mostly novices, except for how fluidly they were maneuvering around the reef. Not one clumsily impacted the reef. When I returned, the first call I made was to Force Fin. Our instructors and I gave the fins a real workout, and they have been our best selling fin line since."
    -John Wall, Owner of The Dive Shop

  • "I also do commercial diving and salvage. Tan Delta Force Fins are compact and maneuverable.
    I can work all day in them without fatigue or cramping."
    - Gary Thomson, Owner of Tri State Diving

  • "I like to call the Original Force Fins the Coral Reef Ecology Fin because they are so compact and maneuverable. They make it easy for even a beginning diver to maneuver around the delicate coral reefs and marine life without inflicting damage."
    -Rich Sallanpa, Owner of Get W.E.T.

  • "...they (Excellerating Force Fins) maneuver with a lot less effort than any regular fin I’ve used..."
    Gary P. Joyce for Sport Diver Magazine, August 1998

  • "In terms of maneuverability the Tan Delta can't be beat..." , "...I found that with the proper foot positioning I could even swim backwards."
    -- Vince Rhodes for Sport Diver Magazine, Nov/Dec Issue 1994


  • "I like the Pros for wreck diving because they're easy to maneuver in confined spaces."
    Jonathon Bird, Emmy Award-winning underwater cinematographer and producer


    Do Force Fins work well for cave diving?
  • "During my last trip to Florida in the fall of 2000, we saw several other cave divers using Force Fins. Another thing I like about Force Fins is the ease of donning and doffing, especially now with the Bungie system. For cold water diving wearing three fingered mitts or even dry gloves, there's no fumbling with the fin strap and they don't break. I could go on and on, but I think you get the point...
    I LOVE MY FORCE FINS!!
    "
    - Betsy Carter, of Victory Sports

    Do Force Fins work well for drysuit diving?

  • "First time I tried them... a friend convinced me to try them many years ago. Finally, he left a pair with me. I was doing some abalone diving. I was wearing a big, baggy old drysuit. Force Fins got me down, did the the job and made a believer out of me. I've been diving with them ever since."
    -Dennis Withner, Owner of Washington Divers

  • "I used an extra-large size, which fitted my size-nine drysuit boots perfectly."
    -Matt Crowther, from Dive Magazine

  • "I'm a rather experienced diver,with 1950 dives throughout the world, but most in Norwegian waters. I do both summer and winter diving, most of the time with the Viking Pro divesuit. During my dives I had no problem swimming as fast as my friends with "ordinary" flippers. If you have some friends that own Force Fins of your size, try to borrow them for a few dives. The first few times you may feel like you're wearing no flippers at all. Most divers I know get used to that feeling and they love it! I love to use my Force Fins while taking under water photos, standing on my knees on the sea bed. They are easy to put on and off and you can have them on while walking on the shore; much easier than with conventional fins. The Force Fin Pro will economize your swimming efforts/power and they have a special "flip"/backstroke because of the "snappy" polyurethane material that gives you "free power". We will not swap with anyone!!"
    -Dag Deberitz, Norweigan drysuit diver
