Ron, You have been great support for us over the years. I have a Cobalt 1 that due to covid has been unused for some time. I tried to charge it, the computer comes up on the charger the battery showed to be charged but when charger was removed the computer died. Opened the battery compartment...

Sorry for the late reply, I didn't see a message that there was an update. I don't see any reason that Fluorocarbon O-ring would not work. Typically the Buna-N O-rings are used in most cases for SCUBA. I used Buna-N on my QD maintenance and had good luck with them "AS568-003 B90 (NBR) Buna-N...

Ron, Feel free to do that, always great to hear from you. You provide great support for the Cobalt and have been a big help to me in the past. I hope that Atomic continues to produce top quality dive gear, I really like their regulators and the Cobalt, I have the Cobalt 1 and other than having...

The one that you see when you disconnect your computer is the 003 90. It is not hard to disassemble the QD and that o-ring is much easier to service with it disassembled. If you pull the boot down from the QD you will see how to remove the QD assembly from the hose, it works out that the QD...

Thank you for your reply, I have resolved this issue. I have been able to source all the O-rings I needed from "the o-ring store" www.theoringstore.com. The O-rings you need are Qnty 2 size 003 90 durometer, Qnty 1 size 009 70 durometer, Qnty 1 size 012 70 durometer, and the 2 small inner...

I have 3 of these scooters when they were made by SeaDoo. I have 2 of the 350s and 1 of the 500. I will say their is a difference in the power of the 2 models. I find both acceptable for cruising around the reef, most of the time I don't take it out of the middle speed. If you are looking at...

Thanks for all the help. When I look up the 901 size (I don't see it listed as a 3-901 and searching did find the 3-901) the O-ring is too large, it's ID is 4.7mm and OD is 7.5mm which would be to large, it would need an OD closer to the 4.7mm. I believe the Oceanic QD uses the 901. I have the...

Thank you for your reply's, after posting this I went back and looked at it closer and figured out how to disassemble the Quick Disconnect. Once disassembled I was able to replace the O-ring on the Spindles that go into computer. Also replace the 2 O-rings in the body. One additional question...

Has anyone replaced the o-ring between the Cobalt 1 and Quick Disconnect? Can this be done without tools or do I need the follow tool to get it installed. Atomic Aquatics Cobalt O'ring Kit The o-ring that seals the hose is easy it the one that seals the computer connection that seem to need...

Whysocold: Thank you for the offer, not in that part of the country. Ron's contact at Huish Outdoors really came through for me, I got the new magnets today and all is working again. Thank you so much Ron you are a great asset to Atomic and have helped me few times when I have posted.

Ron, I hope you are still monitoring this thread. I have a Cobalt 1. A couple of my buttons stopped working so I used the instructions that I go from you some time ago to remove the cover. I cleaned the magnets which were rusty and that seemed to help a little but I still do have use of all the...

I often start a conversation with divers I don't know by asking about their gear. Divers like to explain what they have and why it's the best; let’s face it we are all proud of the neat stuff we use. This gives you the chance to learn about other gear that maybe you LDS doesn't carry and...

Thanks for the great report. Big Fan of Cayman's Sister Islands. I will be going to the Brac in a couple of months.

Ron, I tried to update using the PC Cobalt Logbook tool. It looked like it was working but after more 1.5hrs it was doing nothing. It now is at the Connect to PC screen showing connected and will not respond to any buttons. What would you suggest the next steps to be.

If you are planning a trip to Cayman and your trip is primarily for diving I would suggest Cayman Brac or Little Cayman.

I use a Cinch Strap with my watch 12 x 1 Inch Cinch Straps - 5 Pack - Secure(tm) . You can get different lengths and widths to fit your needs. They don't cost much and are functional. For my watch the 12 x 1 inch works great. The strap goes through both pin so if you pop one pin you don't loose...

For me the first thing I would suggest is a good regulator. I have seen rental regulator mistreated in many way in my years of diving. The last thing I want to have a problem with at 100+ feet is my air supply. If I have air I can deal with pretty much any of the other problems. If I have an...

I use a 12 x 1 Inch Cinch Straps for my watch so that if it gets snagged and 1 pin pops I don't lose my watch. It is comfortable even on bare skin and it doesn't look bad. I have used the 12" with wet suit and dry suit and the length works fine. The 1” width is a perfect fit for my...

There is another dive operation now open on The Brac "Brac Scuba Shack" Cayman Brac Diving with Brac Scuba Shack and cater to smaller groups. It is run by Martin and Liesel a couple that has a long standing on the Island and very knowledgeable about the local diving. Definitely an option worth...

I think you will enjoy the BRR. They are a great group of people, very professional dive opp. I would agree HH did a great job covering it. Some of the places we like for eating, take out at Berry’s Jerk Chicken (Friday night get jerk chichen or pork or both) and the Coral Isle. Food a BRR...
