My name is Jim,and I am a new member to this site,it seems very honest and helpfull and I will now relate a diving accident that happened to me in August in Cocos Island 350 miles off Costa Rica.
I am a inspiration diver for the past 3 years ,logged over 170 hours shallow and trimix levels mainly shooting Tv shows and documentaries from Canada.In all the dives I have never had one problem with my unit,and my 4 dive buddies all have the classic unit with 3 new evolutions added this last 7 months to the pile,all with no problems.My buddy and I Ralph Hoskins from Canada ventured on board the Okeanous Aggressor for my third and Ralph,s first trip to Cocos.
Both of us on classics,we had checked them prior to the trip and replaced all cells and came with fresh batteries.
On the 14 th dive of the week,we dived the Alcion site,incredibly high current,the morning dive went without a hitch,So we decided a 1100am dive at the same spot.
Ralph and I were at the back of the 10 metre zodia,when we rounded the open ocean corner into vicous wave action,the pilot gunned the boat and I went flying rebreather and all smashing hard onto the fiberglass rib floor,jarring the classic badly.I checked it out and once anchored headed into the current down the line.A diver in front of me lost his tank out of a scubapro bc suicide snap system and I was the only one close to grab him , and the tank and try put it all back together in a 5 knot current hanging onto the rope, the line as well,We were only 25 ft. down,I completed the repair and off he went,Ralph had stopped and turned about watching us and waited for me.I started handover hand pulling down the line,Ralph said I pulled slower and slower and passed out,rolled over, out came the loop and I started my descent.Thankgod Ralph was right on me at 68 ft my computer locked out and 6 minutes into the dive,Ralph tried to get a response from me,I was dead in the water eyes closed and non responsive,he could not put my bailout reg in my mouth,I was vsa at this time.He hauled me back to the rough surface and attempted to signal the zod pilot,for 10 minutes Ralph kept me afloat,he says I started breathing.
I woke up stripped to my wetsuit in the zod spiting up blood and wondering what was going on,did I fall down and knock myself out.
I had no feeling of any pain and did not remember the incident,or feel any symptoms or hear any alarm go off,neither did Ralph hear a alarm.

Back on the mother ship I peeled out of my suit washed off and layed upstairs on a lounge chair for the next 32 hours while I was fed pure O2 from the large bank on board.The diving Dr. arrived 50 miles out from shore at 400am in a fast boat, with the ambulance crew, who stabilized me and I spent a lovely 3 days in critical care in Costa Rica,missing my flight home.Ralph hung with me and stripped down my unit and boxed it up making certain checks on the unit first.
The fill was fresh and the O2 at 2000psi,the computers worked and showed cell 3 was off a little,the unit had of course flooded so it is hard to tell what went wrong,perhaps the massive smash off the zodiac deck had upset the works.When I returned the unit to Mike Fowler,Mike replaced a battery box,my unit had the old solid brass pins and it looked like one pin had seized up perhaps unseating the battery thus no alarm for low O2.
I was back diving the unit in mid September and ordered my Vision upgrade for January to arrive.
My wife wanted me to sell the unit and get out of CCR diving,I told her usually it is diver failure, that caused most problems and some of my CCR buddies felt the massive smash on the floor of the zod caused it to unseat a battery thus no alarm,anyway I am back at it and,being very fit and on pure O2 for the 32 hour 350 mile ride home kept me alive,
I would like to thanks Wayne Hasson of the Aggressor fleet and the owner for all there help,and the guest as well who lost a day or so of diving.Thanks to is sweet..............
Ralph is getting a free trip to Truk Lagoon for saving my butt,thanks Ralph..
