Check Dive

An easy first dive with a new operator or after a break, used to verify weighting, buoyancy, and comfort before more demanding dives.

A check dive is an easy, low pressure first dive that a dive operator runs before taking you on more demanding sites. It is standard practice at the start of a liveaboard trip or a multi day dive package: the group dives a simple site, often the house reef or a shallow sandy bay, while guides watch how each diver handles weighting, buoyancy, and basic skills.

For the diver, the check dive solves practical problems early. You confirm your weighting with a proper weight check, adjust to rented gear or a different exposure suit, tune your trim, and shake off rust if it has been a while since your last dive. For the operator, it establishes trust: guides learn each diver's air consumption and comfort level, which shapes buddy pairing and site selection for the rest of the trip.

Treat it as a tune up rather than a test. Nobody fails a check dive; at worst a guide suggests an easier site or a private refresher before the bigger dives. Note your final weighting, suit, and tank type in your dive log while they are fresh, because that combination is exactly what you will want to reproduce at the start of the next trip.
