TUSA Freedom CEOS Mask
TUSA Freedom CEOS mask
The Freedom CEOS is the mask we hand to divers who need prescription lenses and do not want to compromise on everything else to get them. It is a proper low-volume twin-lens mask that happens to take corrective inserts, rather than a corrective mask that happens to dive.
TUSA's Freedom Technology is the part worth understanding. The skirt is engineered to flex where your face moves, which reduces both leakage and the skin marks that come from cranking a strap tight to stop a leak that was never a strap problem.
Because it accepts TUSA MC-7500 corrective lenses, it is the model we recommend most often across our scuba diving masks range for divers who wear glasses.

Corrective lenses are ordered separately
The MC-7500 lenses are a separate purchase and come in fixed dioptre steps rather than to prescription. Bring your prescription in and we will work out the closest step for each eye, which for most people is close enough to read a gauge and see a fish.
Why divers choose the Freedom CEOS
Prescription without the compromise
Most masks that take corrective lenses are bulky, high-volume and dated. The CEOS is genuinely low profile, so divers who need lenses are not stuck with a worse mask than everyone else on the boat.
Freedom Technology reduces the leak-and-tighten cycle
A skirt that flexes with your face seals at lower strap tension. That means fewer leaks, less pressure on the bridge of the nose, and no deep red mask ring at the end of the dive.
Buckles on the skirt, not the frame
Skirt-mounted buckles let the strap pivot with your head rather than levering against the frame. It is the same reasoning as a swivel buckle on a BCD, and it makes the mask sit better on more face shapes.
Twin lens is easier to live with
Twin-lens masks sit closer to the face than single-lens designs, which lowers volume, and they are the only way to get corrective inserts. If you need lenses, this format is not optional.
Features that matter underwater
Low-volume twin lens
Wide field of view for the format, easy to clear, and quick to equalise. Reduced drag matters less than divers think, but the clearing does not.
3-D anatomical strap
Spreads pressure across the back of the head instead of concentrating it in a band. Worth having if you dive in a hood, where a flat strap tends to slide.
Round-edge skirt
Softer contact all the way round the seal. This is the feature that shows up at the end of a two-hour dive rather than at the start.
Anti-fog lens option
ML-7500S AR and UV lenses are available if fogging or glare is a particular problem for you. Most divers do not need them, but they exist.
Fit test any mask before buying
Hold it to your face without the strap and breathe in gently through your nose. If it seals and holds, it fits you. If it does not, no amount of strap tension will fix it. This applies to the CEOS as much as to anything else.
Who the Freedom CEOS is for
- Divers who need corrective lenses and want a modern low-profile mask
- Anyone who has had persistent leaks from a stiff-skirted mask
- Divers in hoods who want a strap that stays put
- New divers wanting a reliable mask that will not need replacing
- Divers with narrower faces who struggle with large single-lens masks
Who it may not be for: if you do not need prescription lenses and want the absolute widest view, a modern single-lens mask like the Fourth Element Seeker gives you more glass and a more open feel.

Frequently asked questions
Can prescription lenses be fitted to the TUSA Freedom CEOS?
Yes. It accepts TUSA MC-7500 corrective lenses, sold separately. They come in fixed dioptre steps rather than made to prescription, so bring your prescription and we will match the closest step per eye.
What is TUSA Freedom Technology?
It is TUSA's skirt design, engineered to flex with the contours of your face. The practical result is a seal at lower strap tension, which means fewer leaks and less pressure on the nose and cheeks.
Is the Freedom CEOS a low volume mask?
Yes. It is a low-volume, low-profile twin lens, so it is quick to equalise and easy to clear despite accepting corrective inserts.
Will the CEOS fit a smaller face?
It suits small to medium faces well, which is one reason we recommend it often. As with any mask, test the seal without the strap before buying.
Can I dive the Freedom CEOS with a hood?
Yes, and the 3-D anatomical strap helps here. A flat strap tends to slide on neoprene, while the shaped strap holds position better.
