diving facilities

for all your tech dives

TDI Sidemount is a technically focused course teaching the use of two primary side mounted cylinders. For the recreational diver this means redundant gas for increased safety, longer dives with increased gas quantity and greater streamlining. For technical divers side mount allows for diving in areas with limited access to twins and is ideal for divers interested in expanding their diving to overhead environments such as caves or wrecks.
