Jackets, regulator sets, masks, fins and weights, and a service card inside every bag with the date on it. Computers and wetsuits are hired separately because sizing matters more with those two.
There are always two spare regulator sets on the boat. If yours breathes wet, hand it over and take a spare rather than finishing a dive on gear you are unhappy with.
We will also service your own regulator while you are here, and tell you honestly if a first stage is past saving.
