Nick N., U.S. Navy Seal
“I have evaluated a wide variety of fin types, of all the fins I have used none have provided me
with the performance equal to the Mantaray Dual Water Channeling System. I found the
Mantaray Dual Water Channeling System would provide me with better speed and less
fatigue than any fins I had used before or have used since.”
Popular Science Magazine
“The Mantaray fins increased the agility and thrust and decreases leg fatigue.”
Michael Timm, Former Military Diver, General Manager, Dive California
“Our Team and I are extremely excited and impressed with the overall performance of the
APS Mantaray Dive Fins. The superb performance with all variety of fin kicks is awesome for
wreck and cave penetration because of its size and maneuverability, little effort to kick,
smooth and relaxing on long swims on the surface to the actual dive destination, under more
extreme conditions in strong currents with surge, in shorts, wetsuit and drysuit, the Mantaray
performed exceptionally great. It performed equally superior on the surface as underwater
with a single tank or doubles 100/120. The foot pocket is very comfortable and fits my
neoprene booties as well as my drysuit shoes without switching sizes or even fins. The
lightweight is great for traveling.”
Scott Friesen, former Clearance Diver for the Canadian Navy, SDI/TDI Instructor, Alpha
Dive Services
"As a dive instructor and scuba shop owner, I tend to use my dive gear on a daily basis. You
know what gear works well under all conditions and what you can rely on. In my former job
as a Clearance Diver in the Canadian Navy, I used Turtle Fins almost exclusively. I made
many dives all over the world using those fins and never thought of changing. When I retired
from the military and bought a dive shop, I continued to use those fins because that is what I
was used to. One day I had a customer come in. He was probably 6'6" tall and had size 15
feet. We were able to outfit him with everything except fins. I finally gave in and sold him my
turtle fins. On my next several dives I tried various fins we had in stock and in rental but
couldn't find any to my liking. I mentioned my fin woes to one of my suppliers one day and he
suggested trying out a pair of Mantarays. He was a former commercial diver and had always
used Jet Fins and Turtle Fins, but now he swore by these fins. I decided it wouldn't hurt to
give them a try. I was very comfortable diving with these fins right from the first dive. I was
amazed at how much forward thrust was achieved with such a small blade. They worked
great even when diving with doubles and carrying multiple stage bottles. They have just the
right amount of flex and are so light it feels like you are not wearing any fins at all. The
smaller blade size makes it easier to climb up dive boat ladders as well. I have about 250
dives on Mantaray Fins now and wouldn't think of using anything else. Congratulations on a
well designed fin."
David Feldman, M.D.
"We purchased our fins from you prior to our trip to Honduras. We were looking for fins that
weren't as heavy or as large as our Apollo or ScubaPro fins. As we have a friend who uses
your fins here in California we were excited to give the Mantaray a try. Well we are very
pleased, besides being light weight and comparatively small they performed beautifully with
a variety of kicks, flutter, frog and helicopter, and in a variety of conditions. We have shelved
our other fins and plan on using the Mantaray exclusively for all of our diving."
Jim Westphal, Dive Rescue Instructor
I had a chance to use the Mantaray fins in the Cenotes in Mexico and the currents of
Cozumel. I love the way they handle with different kicks, especially the frog kick in the
caverns! They blew my twin jests away! I will introduce them to all my students and fellow
Dive Rescue personnel…Thank you!
Michael King, Dive Instructor, San Diego, CA
This is an incredible fin with the best of the split fin and the best of the paddle fin all in one.
And packaged in a small, very packable package. I have used this fin in the warm waters of
Roatan, Belize, Philippines and found it to be fantastic in power and hard thrust. Unlike the
split fins that you can overkick ... that is unheard of with these fins. The harder you kick the
power is there. But it is easy on the knees and ankles at the same time (like the split fin). I
have even used the fin with my drysuit in California diving and surf diving. Making your way
thru kelp is a breeze with these smaller fins and they do not get hung up in the kelp like other
ones in my bag. With thier size they are ideal for travel and those bulky fin pockets on alot of
bags are not used for my fins anymore and I can get a lighter bag to save on weight and just
put the fins right in the bag ... that 50lb limit becomes less of an issue. Thanks for coming up
with a great product. I need to order a white pair for the visibility effect with my students and
with my buddies.
Mark S. Brown, M.A., EMT-P, NAUI 4546, SDLG LG (La Jolla Cove Lifeguard)
“A member of the Dive Team and River Rescue Team. In my recommendation for the
Mantaray Dual Water Channeling System Dive Fins, I was very impressed with the fins thrust
and power, without exerting nearly as much effort.”
Matt Karl, Huntington Beach Life Guard and Dive Rescue Team
“The Mantaray Dual Water Channeling System Dive Fins worked great. Despite being
shorter, they still provided good thrust with a comfortable flex pattern which is much more
forgiving on beach entries and large search patterns. Easy to get on and off with no plastic
connections that often break.”
Jeremiah B., U.S. Coast Guard
“I had the opportunity to try the Mantaray Dual Water Channeling System Dive Fin design. The
word that came to mind was ‘effortless’ giving me the propulsion I needed while consuming
less energy. I now use the Mantaray Dual Water Channeling System for both military and
recreational dives.”
Joel M., U.S. Navy Seal Team Three
“Mantaray Dual Water Channeling System Dive Fins – I was wearing Twin 80s, I was quite
impressed by the fins they were very mobile with excellent thrust. My legs were not nearly as
fatigued as when I used my personal fins….very navigable in shallow water. I highly
recommend the opportunity to anyone who is an avid diver or surface swimmer to examine
these fins.”
Kathleen Stogsdall, Owner, I.B. Divers NAUI Training Facility, 9th Street, Imperial Beach, CA
“The Mantaray Dual Water Channeling System dive fin brings innovated design features. The
diver gets a high thrust and efficient kick with minimum stress to the leg muscles. There is
no cramping of the leg or calf muscles. The weight and length of the Mantaray dive fins make
it low impact and environmentally friendly. The foot pocket design allows me to use the
same size fins with either wet suit booties or the DUI dry suit rock boots. I have been diving
the Mantaray dive fins for over two years. The Mantaray dive fins are more efficient and more
comfortable than any paddle fins on the market. When I lend my Mantaray dive fins to a
student or dive buddy that diver buys a pair of Mantaray Dual Water Channeling System dive
fins.”
Stephanie Truhlar, Avid Diver and Member and Volunteer of the Bottom Bunch Dive Club,
San Diego Council of Divers, and Ocean’s Foundation
“I bought another pair of split fins for my dry suit and had trouble keeping up with the group.
Frustrated, I decided to test the Mantaray Dual Water Channeling System dive fins. I found
that the Mantaray dive fins were very easy to put on in the surf; they gave a lot of power both on
the surface and below the water. I am now able to use a variety of different kicks to minimize
silting because the fins are so adaptable. Packing, the Mantaray dive fins easily fit into all of
my containers. This is an amazing fin, especially for the price. I’ve been very happy with
them, except sometimes my buddies have trouble keeping up! I recommend the Mantaray
Dual Water Channeling System dive fins and my husband just purchased a pair.”
Bill Walkup, Dive Instructor
“I noticed the Mantaray fins provided a greater amount of thrust and it felt as if I didn’t even
have any fins on. Once we descended and began our dive, I utilized numerous kick
techniques. I found the fins to be suitable for all of them. I made this particular dive
numerous times and generally make it back with between 500 and 750 pounds on a steel
72. This time I made it back with slightly over 1,000 PSI. The fins helped with my air
consumption.”
Jon Hardy, Argo Diving Service
“It was a pleasure to test dive your Mantaray fins. Efficiency was very high, in fact among the
best of fins we have tested.”
Kristian Wilcox, PADI Dive Master
“The first time I tried the Mantaray Dual Water Channeling System I was blown away. The
speed that can be generated is just unbelievable matched with excellent maneuverability.
These fins are second to none.”
Cary Humphries, Dive Locker Supervisor, Scripps Institute of Oceanography
“My test dives proved successful and I thoroughly enjoyed your Mantaray design’s versatility.
It showed good thrust with smaller surface area. It allowed me to work in tight areas with
excellent pivoting abilities. I was able to swim a long distance without excessive fatigue.
They proved light yet stable.”
Peter Scoones, Underwater Cinematographer
“I was most impressed with the Mantaray. They were the closest to my ideal fin I have come
across. I think you have come up with a design that really works.”
Steve Douglas, Underwater Video Photographer and Film Festival Contributor Worldwide
“The Mantaray Dual Water Channeling System Dive Fins are very lightweight. I had major
doubts that the fins could stand up to the test I would be giving it and to the efficiency of the
fins I have been using these last several years, I couldn’t have been more wrong. I found the
foot pocket to be the most comfortable I have ever used, allowing me to get closer without
kicking up the bottom and obscuring the filming. At the dive sight we were forced to swim
back to the boat into a strong 3 knot current. My friend and partner was about 15 meters
ahead of me. The Mantaray Dual Water Channeling System Dive Fin’s excellent propulsion
brought me head to head in no time without much effort at all.”
