I have this and have used it but don’t see a difference as long as you dry it well with enough dry air. I have a large dive compressor which makes that easier with dry air available. Most of the people I see with rusty tanks are getting bad fills from poorly maintained compressors or...

Use enough air and have the bottle upside down completely you should be good. If you use 1/2” pex to get the air up into the cylinder that should help. You could try a rust inhibitor at the end of your process but as long as you do things quickly you should be okay without it. How much air are...

I use a milk crate for all the things that require charging and zip tie a surge protector to the side with all the chargers in it. When I go to a sight or on a trip you only need to unplug one plug and pick up and go. When you get home you only need to plug one plug and it’s all charging at this...

I agree that diving the wall in a kayak would be something to try after you mastered getting in and out. Maybe not on a weekend. Fun place to dive but boat traffic would be problematic on a weekend.

I’ve never removed my CCR underwater but have seen it done in front of me. No stars, would not recommend.

Packed up the car and left?! Wow, that’s horrible.

You only fill an aluminum 80 to 2400 psi? Why not just go with a steel low pressure if you are that concerned? I fill mine to 3000 without any concern. I guess it’s whatever you are willing to risk but I don’t see it as a big risk to do so.

I think there is a lot to be said about this subject. I started on backmounted rebreather then moved to sidemount. I think the older sidemount systems is actually having the entire rebreather on one side versus the sidewinder makes sense to start backmount but with sidewinder there isn’t the...

Buy a used shearwater petrel 1. Cheap and works great. I see a few on the market now.

When I dive my sidewinder I don’t use any weight in a drysuit with arctic undergarments. I also don’t use my wing at all. I would be comfortably diving that way in open water but in open water I would likely be on my hammerhead which I also don’t use any weight and rarely use my BC. I think...

Well I updated my vacation cave diving mobile this evening. I was using battery powered lights under my custom rack I built but decided to go with a hardwired version that allows me to take the rack in and out disconnecting easily. Another feature I wanted to add was a switch in the back that...

I can’t find any actual information on this event (rebreather brand, rebreather age, how long the alarms were going off), or really any information other than this site has had many fatalities, mostly training related it would seem from a quick google search. Hard to pass judgement “of the...

Definitely not a good idea. I’ve seen people use them on tanks they plan to leave staged in part of the cave and felt they would have less chance of loss of gas. Neither are necessary and the act of opening the valve is part of the process to ensure you have the right bottle. I would advise...

I agree. 1 on 1 would be best.

Kave Kardashians!! Lol, that is the funniest description I’ve heard yet. As for the instruction, I don’t think it’s bad as long as the people in it knew what they were getting into. You’ve likely seen the military training and it’s not much different. They covered the stress part. People are...
