[Dive now work never]

I find underwater tig a good deco game but played by removing part of your buddies kit (mask, fin, side mount, knife, camera etc). Always tends to illicit a reaction especially if instigated on the spur of the moment without the other divers knowledge. First to the surface with the most kit/ alive/ not bent wins.

Underwater fencing with other divers at the deco trapeze a winner, a perfect opportunity to recreate Thunderball on a small scale. For authenticity you must make sure members of each team have the same colour drysuits. Cutting through hoses is not allowed but the use of jet packs should be encouraged whenever possible. For extra thrills, get the skipper to throw thunderflashs in whilst the game is in progress.

Messing with the beasties is not to be encouraged, one day the starfish will know how to switch off a cylinder!!
