Rebreather Diving Tek Dive Cocos Island Costa Rica

and no controls to operate underwater except for the valve that opens the Nitrox gas supply to the circuit, thatīs it! Everything is preset at the surface as you plan each dive with the appropriate Nitrox mix and the proper gas flow rate for the maximum operating depth that you intend to dive.

This basically means that you have to prepare your equipment carefully prior to your dive and stick to your plans. The preparation of your rebreather is crucial. We like to compare its importance to the skydiver who folds his or her own parachute before a high altitude dive. The technical diver has to learn new skills and adopt a professional attitude in the safe practice of "rebreather" diving.

With rebreathers the benefits are numerous. You can take advantage of the extended bottom time that Nitrox gives you, the autonomy that an efficient rebreather can give you by recycling as much as 80% of the gas when using SCRs (Semi Closed Rebreather) and, the ability to reduce significantly the noise factor experienced with an "Open-Circuit".
