TS Tec Sidemount Diver

The IANTD TS Technical Open Water Sidemount Diver course is the next level of sidmount diving with the TS system. Here basic training units are discussed and learned which are necessary to carry more than 2 tanks. The special techniques are to master use 4-6 tanks safely and in a controlled manner. This course is for those who already have experience in general sidemount diving and are now ready to familiarize themselves with these techniques. The focus is on special configuration of the equipment. The training prepares the diver conscientiously for the next level like Cave Diver or Trimix Diver. Fine details and repetition of procedures allow safe handling of the TS system and several tanks. The correct processes are carefully rehearsed to master the system safely. This course is not about going to great depths or diving into caves, but is about mastering the techniques with several tanks and then being safe and well prepared for the next level.
