G'day,
On a typical recreation dive my safety gear consists of:
Spare mask in left thigh pocket, whistle on BC, Dive Alert air horn, knife on waist band, 6 ft self-inflating DSMB attached to a ratchet reel with 75 metres of line, second dive computer (usually in guage mode) and compass on right arm, backup torch clipped to BC, and I've just added a Nautilus Lifeline in my right thigh pocket. Both of my BCs have dual bladder wings for extra redundancy.
If I'm on a liveaboard dive trip I also carry a personal EPIRB with GPS in a canister on my waist band. If the boat goes without me, I'm going to summon the emergency services.
These days when on dive trips, I usually dive with twins, either using them independently or joined with a manifold.
If I'm technical diving I also add a finger spool reel in my right thigh pocket, a line cutter on my waist band and wet notes in my right thigh pocket.
I've had an experience boat diving locally where the Nautilus Lifeline would have proved useful, so I purchased one when they became available.
I've done more than 350 dives with a dual bladder BC without ever needing to use the second bladder. Then when at 55 metres on the HMIJS Natago at Bikini Atoll I went to inflate only to find my primary inflator didn't work. After several attempts I gave up on it. After all, I have a second inflator and bladder. This is situation is just what it's for. So I switch to it. At first it seems fine, but then the inflator free flows. Bugger! Jammed myself under a part of the wreck and dealt with the problem by dumping air and disconnecting the inflator hose. I was extremely attentive to my buoyancy control for the rest of the dive and kept a hand on the buoy line on my ascent. You never know when you might need your safety gear, and even then you need to be able to deal with it not working or causing you extra grief!
Best regards, Lloyd Borrett.
