A CCR is an artificial lung (aqualung) by which the diver’s exhaled breath is partially cleanedand filtered of carbon dioxide, mixed with additional oxygen, and then breathed again by the diver. Hence the name “rebreather.” The TEK system comes in a variety of models with a variety of features all suitable for your advanced scuba diving needs.

Why would anyone use a CCR? Most divers who try and use rebreathers do so in order to get closer to marine life. The pressure waves and noise caused by exhaled bubbles can be a huge obstruction when interacting with marine life at close range.

Moist air in CCRs also stop dry mouth occurrence and lessen the factors of diver exhaustion.

Divers using rebreather equipment benefit and enjoy a greater freedom of movement made possible by lightweight, one-piece breathing units. There are a number of semi-closed systems that, when completely configured and ready to dive, weigh less than a standard 80-cubic-foot cylinder.


They are fundamentally complex items of equipment anddo come with a variety of advanced features, designs and system varietiessuch as semi-closed circuits and fully closed-circuit systems, also called diversification series. Some models come with extensive sets of features such as software and electronics designed for intelligent monitoring, vibrating alarms, quick-disconnect systems, and even heads-up-displays.

Some models may even offer enhanced features of convenience. For instance, to be ready to dive, the Prism2 TEK rebreather diver needs only to add a supply of cylinders. The Prism 2 model conveniently accepts a very wide range of aluminum or steel cylinder sizes, available from your diving gear supplier.

The TEK Gear Sentinel Scuba model, for instance, offers an electronics-driven fully closed-circuit constant PO2 design rebreather (eCCR) that provides an intelligent and easy-to-use life-support system (LSS).


Rebreathers overall and closed-circuit rebreathers specifically provide three essential advantages over open-circuit scuba systems, namely:

  • More proficient use of gas:Gas is only used when the rebreather needs and requires it, employing purely mechanical methods
  • Optimized decompression characteristics: Byimproving the proportion of inert gases in the breathing mix, this rebreatherminimizes the decompression requirements of the diver
  • Almost-silent operation: Your diving experience will become more rewarding, pleasant and enjoyable, allowing you concentrate on the visual aspects of scuba diving such as underwater photography or videography
  • Increase of bottom time: Your diving freedom can grow by using a rebreather; the bottom time can in many cases be more than doubled by doing a decompression stop of less than 10 minutes.
  • Lightweight:Because of the lower weight, rebreather divers enjoy the freedom of movement made possible by modern, lightweight, one-piece breathing units.


There are a few disadvantages that come along with rebreathers because of the complexity of gears. They demand a diver’s discipline to be higher and may in fact require some special training, resulting in extra efforts and expenditure. There are:

  • Higher Costs:Obviously, because of the complexity of the design, the cost element is higher than with simple open-circuit gears. Even low-end rebreather designs may cost several thousands of dollars plus the cost for additional training
  • Risks of failure and human handling errors: Rebreathers have an innately higher risk of mechanical failure as an obvious result of their design complexity.However,this can largely be offset by good a design that incorporates redundancy and by carrying adequate alternative gas sources (i.e. ‘open-circuit bailout’) in the event of a system letdown.

While rebreather diving may sound scary, accidents may further be reduced by:

  • Specialized Diver Training:Learn how to use the equipment and follow the procedures of using a particular rebreather design in order to minimize the chances of human-machine interaction errors.
  • Higher Learning Curve: Because of the somewhat increased complexity of equipment, divers have to accept a slightly increased learning curve.

When you compare rebreathers on the market, consider that the TEK Gear Rebreathers are some of the most sought after scuba diving items today. Expect and consider,though,that all rebreather models may have certain advantages and disadvantages over others. Unfortunately, a “try and dive with it first” attitude may not make you aware of minor shortcomings of a particular model right away. This is why it is imperative to discuss with your diving instructor what type of diving gear you are presently using, as well as your goals with the equipment over the next three to five years.

Using TEK Gear Rebreathers will nevertheless give you confidence that you have made a wise and technically sound choice, enhancing and maximizing your diving freedom and aquatic recreational experience.
