Rebreathers (CCR)
Diving without bubbles has advantages with wildlife and also the general marine environment. The fish and other creature are not put off when bubbles are exhaled and therefore you can get a lot closer to them. Bubbles can also dislodge overhead particles in wrecks, reefs and caves so the rebreather diver is also conserving nature while underwater.

Cave Diving
You can also engage in cave, cavern and sinkhole diving if that interests you. The training for these environments is challenging and will stand you in good stead to join your fellow cave diving friends and also meet new ones.
