SMBCI/T - AP Training Surface Marker Buoy
The AP Training SMB is identical in design to the rest of the AP self-sealing SMB range, only much smaller - just 2 litres capacity - which allows the trainee diver to practice deployment of the SMB multiple times without serious depletion of their gas supplies.
The instructor can supervise the student inflating the SMB and sending it to the surface, then pull it back down (still inflated), deflate it and hand it back to the student to try again.
Deploy, inflate and launch… pull it down, deflate, relaunch, repeat…
Inflation is achieved in the usual way by inserting a regulator or other second stage air source into the mouth of the buoy.
The SMBC/T features the original AP self-sealing baffle in the mouth which seals on inflation to prevent gas loss from the buoy at the surface.
Deflation is achieved with the dump/over-pressure valve.
The AP SMBC/T is also available (from this site) with an Easifil hose inflator or a 0.1 litre DIN cylinder (or both) to allow trainees to practice deployment with all 3 methods of inflation.
