A thila in current is a different ocean. The reef-fish hunker down, the apex predators come up from the blue, and the diver who can hold position eats well — visually speaking.
Read the tide first.
Incoming current pulls clean blue water through the channel and brings the big animals with it. Outgoing flushes the lagoon — visibility drops, but mantas often follow the plankton out. Always check the tide chart before you check your gauges.
Negative entries, every time.
Step off the boat with no air in your BCD. Down to ten metres before the current grabs you. Hesitate on the surface and you're a kilometre downstream by the time you regroup.
Reef hooks: the etiquette.
Hook into dead rock or rubble — never into living coral. Two metres of line, no more, so you stay close to the structure. Inflate just enough to hover. Unhook with the current behind you so the line releases cleanly.
Watch the blue, not the reef.
The reef is theatre. The blue is where the show happens. Hammerheads, eagle rays, schools of jacks — they all pass through the open water just off the wall. Soft eyes. Wide vision.
The drift is your friend.
When the dive is done, let go and fly. Maldivian drifts can carry you a kilometre on a single tank — the boat will find you. Inflate your SMB at fifteen metres on the safety stop, never at the surface.
