All about SEAC® Full Face Mask CO2 Testing
A feeling of fatigue and a build-up of CO2 in the respiratory system can lead to potentially serious consequences, even during low-impact physical activities like snorkelling.
That’s why SEAC® abides by two fundamental principles in designing its full-face snorkelling masks:
- the user should need to employ the least possible breathing effort, comparable to natural breathing, out of the water and in a relaxing situation;
- and the level of residual carbon dioxide CO2 inside the skirt while inhaling must be well below the safety limits.
Even though there is no specific European regulation governing the manufacture of full-face snorkelling masks, SEAC® has developed a series of specific tests (with their own, in-house testing equipment) that comply with the values set forth by the following European regulations:
- EN 1972:2015 establishes the requirements for the design and manufacture of snorkel tubes, limited to breathing effort;
- EN 16805:2015 establishes the requirements for the design and manufacture of dive masks;
- EN 136:2000 establishes the minimum requirements for the manufacture of full-face respiratory protection masks, limited to tests checking the CO2 in inhaled air; and,
- EN 250:2014 regarding open-circuit compressed-air self-contained breathing apparatus and its components, limited to tests checking the CO2 in inhaled air.
In the SEAC® labs, batches of full-face masks are tested with Ansti machines, specifically to measure the dynamic performance of human breathing, and with proprietary SEAC® equipment to check levels of CO2 in the air inhaled through the masks.
All this makes it possible for them to offer the end user the best possible snorkelling experience, in complete safety, because with SEAC® full-face masks, having fun is as natural as breathing!

Oyster Diving have recently been given exclusive access to offer scuba diving courses and fun dives at Mercers Lake, a beautiful lake near M25/Gatwick in the UK.
Oyster have just launched their own dive boat ‘The Blue Pear’ to explore various parts of the lake. Divers can glide around the underwater woodland, see lots of fish and decent visibility. Out of the water divers set up in the purpose built kitting up area, unwind in a warm shower, and off-gas in the café & licensed bar.
To celebrate the start of the summer season, AquaSports and Oyster Diving have teamed up to host a Star Wars-themed open day on the 4th May.
Guests will be able to enjoy discounted tasters of various watersports including Stand Up Paddleboarding (SUP), Canoeing and Sailing. Oyster Diving will be joined by Apeks and possibly other dive manufacturers to display their latest products. Demo gear will be available for qualified divers and Oyster’s sales support team will be on hand for customers with any questions.
Divers wishing to get in the water will need to book in via Oyster Diving’s website where you can also choose to hire any equipment. Non-divers and well behaved dogs are very welcome!
As well as the watersports there will also be music, food and a licensed bar. The fun starts at 10am and finishes around 4.30pm.
Please come along, wear your finest Stormtrooper or Princess Leia outfit and enjoy the fun!

Dive Rite was founded in 1984 by technical divers and cave explorers with the goal to make the very best scuba diving equipment available. Gear that can be trusted on the most extreme dives and exceed expectations in any environment: reef, wreck, cave, or quarry.
The Nomad Ray is the product of years of design, development, field testing, and feedback from some of the world’s leading sidemount divers and instructors.
The Nomad Ray is available in black, blue, OD green, pink, or red. If you happen to find yourself in a tight spot, the Ray’s abrasion-resistant “skid plate” will have your back: providing wear protection exactly where it’s needed the most. SuperFabric® is a fast drying, highly durable, and slash-resistant material. The Nomad Ray Sidemount System is ready to perform in the toughest diving environments.
The Nomad Ray can be easily adjusted to comfortably fit all body types. The independently adjustable harness design can be quickly set up for any diver. Shoulder and waist webbing can be replaced independently if damaged or trimmed too short. The Nomad Ray uses a fast, tool-free bungee length adjustment system. Simply pull to the desired length, tie a single overhand knot, and tuck the excess into the integrated sleeve. A quick-adjust belly band with a custom moulded bungee hook keeps the wing wrapped snugly around the diver’s body.
A zipper on the inside of the Nomad Ray wing allows for access to three integrated weight pockets capable of holding up to five pounds of each of hard or soft weight.
