Hyperdry Technology: Nothing is
more frustrating than getting a mouthful of water when you're
snorkeling. TUSA's Hyperdry technology keeps the snorkel dry by
diverting water through an independent escape channel. Clearing
the snorkel quickly and easily: TUSA snorkels like the SP-170,
SP-130 and SP-580Q are designed for simple, quick clearing.
Fin Testing Robot: This test
involves scientific testing of energy consumption rates and speed
performance, and then analyzes the resulting data. For instance,
they can measure how long it takes the robot to swim a 20m pool and what
the electrical resistance load was during that time in order to evaluate
fin performance in a manner that's much more scientific than possible
with human testers.
Flow Pool Test: TUSA had 4 adult
maile swimmers use the fins in a flow pool while oxygen uptake and heart
rates were measured. TUSA was able to scientifically evaluate the
difference among leg muscles and fin kicking, as well as measure the
pressure applied to the front and back of the fins using air-pack
contact pressure meters.
Air Consumption Performance Test:
In house testing team performed measurement tests on each of the fins to
determine the air consumption rates and to maximize efficiency.
Global Monitoring: However, TUSA
realilzes that testing under real conditions is very important.
That's why they send out prototype models to diving shops around the
world during development process, in order to have real instructors and
guide divers test them in normal circumstances. Furthermore, they have
monitoring groups which are made up of regular divers who use the
products and give their opinions, which is fed back into the development
process.

astigmatism (second number or cylinder in Rx) below -1.00. Above -1.00
astigmatism, custom made goggle is recommended. This will be made to
your exact prescription as your current glasses are. Custom made
prescriptions require a PD (pupil distance) measurement. We do not
make allowance for the magnification of water unless specified. Custom
goggles are not returnable/refundable. All premade lenses are priced
per lens. For instance, on the pre-fabricated RC-6000, total price with
prescription for both eyes and mask is $226. Custom lenses made direct from
Tusa, and cannot be made by A Sight for Sport Eyes lab. Custom
