What ascent procedures will tech divers in open water follow when currents are mild?
When diving in strong currents, what ascent procedure will tech divers generally use?
Key Points to Remember
When currents are mild and tech divers have a descent/ascent line at their disposal, they will generally use this line to stage their decompression.
When diving in strong currents, using an ascent line is not an option. Divers must be able to “shoot a bag” that is, deploy a Surface Marker Buoy (SMB) and use it to drift while ascending and decompressing.
