TUSA Masks

Freedom

Freedom technology is a set of revolutionary features offering superior fit, comfort and increased performance in TUSA masks. Freedom model masks feature a dimpled skirt surface with varied silicone thicknesses and stability ridges in addition to a proprietary low-friction skirt surface on the fitting line.
Anti-Reflective (A/R) Lens Treatment

Standard glass lenses can reflect up to 15% of available light reducing vision underwater. TUSA’s Anti-Reflective (A/R) Lens Treatment decreases internal and external reflected light. This reduction increases light transmission to 95% resulting in significantly enhanced colour, clarity, contrast and better overall vision underwater.

CrystalView Optical Glass

CrystalView optical glass lenses provide superior clarity, colour and transmission of light over standard glass lenses used by the competition. Up to 15% of available light can be lost with a standard glass lens due to impurities and reflectivity. TUSA’s CrystalView lenses transmit 92% of available light to the diver for clear crisp vision. CrystalView lenses are used in all PRO models masks and also in the M-41 Freedom Quad.
Corrective Lenses

Corrective lenses are offered on several styles of masks. This option allows the diver to choose right and left lens powers in both a variety of diopters for maximum flexibility and for a custom fit.

UV Lens Treatment

Increased exposure to UV light can damage the eyes especially in marine environments where reflectivity is high. TUSA’s UV Lens Treatment provides 100% protection from harmful UVA and UVB rays. Blocking 100% of the ultraviolet spectrum (under 400nm) provides greater eye protection without sacrificing light transmission or vision.
Round Edge Skirt

TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.

3-D Strap

TUSA's patented 3-D strap is a true three-dimensional design that snugly fits against the head's natural curvature. The 3-D strap offers unprecedented comfort and fit unlike standard flat mask straps.
Hyperdry Purge

Clearing a mask has never been easier thanks to our patented Hyperdry System. Simply breathe out through your nose and any water that has accumulated in your mask is forced out through a one-way purge valve. Once the mask is clear, the valve seals shut.

Angle Strap Adjustor

The 5 Angle Strap Adjustor allows for a five position micro-adjustment on both the left and right sides of the mask. This enables vertical (up/down) and horizontal (left/right) pressure on the face to be delicately adjusted for the optimum fit.
Skirt Mounted Quick-Adjust Buckle System

The Quick-Adjust Buckle System incorporates a newly-designed low-profile buckle into the crystal silicone skirt of the mask. The result is a compact, lightweight, technologically advanced mask design that can be easily and quickly adjusted for a perfect fit.

Panoramic View

Panoramic View masks feature a variety of designs offering an incredibly wide field-of-view. Several designs incorporate minimum frame volumes, domed side-windows, reduced frame structures as well as three and four window styles for maximum vision.
   



TUSA Fins

ForcElast

A proprietary TPR compound molded into an advanced blade and foot pocket structure offers superior propulsion, efficiency and power transfer. ForcElast powers TUSA high performance fins like the SF-22 and FF-23.
Anatomic Fin Strap

TUSA open-heel fins are equipped with a newly designed Anatomic Fin Strap (AFS). The AFS is anatomically shaped to offer a balance of flexibility and control to increase comfort, power transfer and to significantly reduce heel slippage found in many standard flat fin straps.

Propeller Technology

The SF-8 and FF-9 X-Pert Zoom split fins employ Propeller-Fin™ Technology, which delivers ultra-high performance with a low amplitude rapid flutter kick. As the fin moves through the water its two wing-shaped surfaces create lift and forward propulsion like a propeller. Any water travelling over the top of the blade is funnelled into and out of the split between the blades. Efficiency is increased while drag and effort is reduced.
Angled Blade Design (A.B.D.)

TUSA's Angled Blade Design is employed on the SF-6 and SF-8 fins. A standard flat fin inhibits propulsion solely by fault of design. An angle between the heel of the foot and the calf of the leg remains when the leg is extended to kick. This angle causes 10% of the propulsion to be lost. The Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.

EZ Strap and Buckle System

TUSA's EZ strap and Buckle System allows fins to be quickly and easily adjusted with minimal effort. Adjustment can be made while the fins are worn, allowing for a precise fit and ease of removal when necessary.
   



TUSA Snorkels

Hyperdry ELITE

A more refined and streamlined version of the Hyperdry MAX, the Hyperdry Elite maintains the same superior dry performance and keeps the snorkel completely void of water by quickly and efficiently closing the gasket when submerged or hit by waves.
Hyperdry MAX Dry Top System

TUSA’s Hyperdry MAX System (pat p.) is the latest innovation in dry snorkel technology utilizing two independent high buoyancy floats for superior dry performance. This revolutionary design keeps the snorkel completely dry by quickly and efficiently closing the gasket when waves or water hits the snorkel.

High Flow Purge

The High Flow Purge design used on TUSA snorkels offers a covered large diameter purge valve for simple, quick clearing, reducing the amount of water remaining in the mouthpiece in an instant.
Comfort Swivel

The Comfort Swivel offers a more comfortable fit since it creates no load on the mouthpiece, straightens out during diving and doesn't get in the way. The swivel adapter makes it possible to slip the mask strap into the slit with no hassles. The two-part construction allows the snorkel to rotate and can be attached in a horizontal position.

Hyperdry System

The Hyperdry System keeps the main pipe dry by ejecting water through an independent escape pipe. This unique design utilizes the angle of the snorkel pipe and the resilience of the water surface to eject water.
   



TUSA BC Jackets

Waist Support System (W.S.S)

The Waist Support System significantly enhances comfort and fit by dispersing the weight load around the hips. The W.S.S. integrates the adjustable shoulder harness system with the rear stabilizing plate and cummerbund to effectively unload the hips while ensuring a snug fit.
Ultimate Stabilizing Harness (U.S.H.)

TUSA's Ultimate Stabilizing Harness completely eliminates tank roll and delivers an amazing fit. The U.S.H. securely holds the air cylinder in place with optimally placed rails and brings the tank closer to the body increasing tank control while reducing weight.

Independent Harness System (I.H.S.)

The Independent Harness System isolates the BC jacket's harness from the air cell, tightly supporting the tank even with changes in air cell inflation/deflation. The I.H.S. prevents tank slippage and eliminates any gaps between the tank and your back.
3-D Air Cell

The 3-D Cubic Air Cell allows for greater internal volume (lift) in a more compact and streamlined design. The 3-D cell increases diver comfort by expanding outwardly away from the body eliminating that "squeezed" feeling upon inflation. It also maximizes efficiency by keeping you more streamlined underwater.

A.W.L.S. (Advanced Weight Loading System)

TUSA's patented Advanced Weight Loading System (A.W.L.S.) allows the diver to insert weight into both left and right weight cartridges eliminating the need for a weight belt. Rear trim pockets combine with the A.W.L.S. to optimally balance the weight load on each TUSA integrated BC jacket.
3-D Hybrid Cubic Air Cell

The 3-D Hybrid Cubic Air Cell combines the features of a wrap-around style BCJ and a back-inflation BCJ into a unique streamlined hybrid design. The air cell offers increased lift capacity over standard back-inflation jackets and a more streamlined, comfortable fit underwater and on the surface.

A.W.L.S. II (Advanced Weight Loading System II)

The 2nd generation A.W.L.S. continues to enhance TUSA weight integrated BC jackets by incorporating a newly designed ergonomic handle grip and quick-lock feature. Load and release the weight cartridges with ease by simply turning the handle grip vertically 90° in either direction.
   



TUSA Instruments

Vibrating Alarm

TUSA's IQ-800 DC-Sapience computer is the world's only computer with an optional vibrating alarm. This unique alarm function is similar to the vibration setting on most cellular telephones. The user is alerted to important dive data with several vibrations instead of an audible alarm that can distract your dive partners.
Audible Alarm

TUSA's IQ-700 and IQ-800 computers feature audible and visual alarms for the most important dive data warnings. Ascent rate, maximum depth, no decompression limits, safety stop and several other key data can be set to alert the diver.

2 Gas Mix

TUSA's IQ-700 DC-Hunter computer features a 2 Gas Mix option. This feature allows the diver to preset two Nitrox gas mixtures (Mix 1 and Mix 2) for easy switching during the dive as necessary. Mix 1: 21 to 50%, Mix 2: 21 to 99%.
PC Downloadable

The PC download function allows the diver to transfer complete log and profile history from the dive computer to a personal computer. TUSA's PCLogbook software allows the user to keep a digital logbook, review dive profiles and plan future dives. A PC interface unit is sold separately.

User Replaceable Battery

Convenience and ease-of-maintenance is imperative in the design of today’s dive computer. Each of TUSA’s computers offer a user-friendly replaceable battery that can be changed on a moment’s notice using standard widely-distributed batteries.
Display Backlight

TUSA's computer instruments incorporate a highly visible backlight display function for low light or night time viewing of dive information. This backlight fixture can be accessed easily by a single push of a button and may be activated on the surface or underwater for a specified length of time.

3 Gas Mix

This advanced feature allows the diver to preset three individual gas mixtures (Mix 1, Mix 2, Mix 3) from 21-100% for easy switching during the dive as necessary.
Air Integration

TUSA’s Zen Air Integration technology allows a diver to monitor depth, dive time and up to 3 tank pressures accurately and safely in a single glance. The need for bulky analog gauge consoles is gone. TUSA’s alphanumeric digital display conveys air data efficiently each updated second.

Hoseless Transmitter
