    Following Line in Large Passages

    I have a question regarding how close you guys stay to the mainline in the bigger passages (eg Bone Line at Ginnie). I really want to explore all of these bigger rooms / areas, rather than just swimming along close to the main line and only seeing a small portion of the cave. But then I wonder...

    What dive shop to rent from?

    I'm a TDI trained diver, but EE has fast become one of my favorite dive shops. Their service is incredible, they are extremely friendly, and they have always made me feel welcome. I start and end all my Ginnie trips there now for fills, tank rentals, and gear purchases. Not being a GUE diver...

    Advice on deco reg set

    I've used the DGX deco first stage for 4 years now for 100% O2 deco. and it has worked great for me (diving at the AN/DP level). It is super cheap and for the cost of a reg service you can buy another one, or they sell the service kits. I have had no issues with mine. I use an Oceanic Alpha 8...

    ???Future of Open Circuit Mixed Gas and Rebreather Diving???

    For me, I started noticing that when I was relaxed, doing very little effort, and in great conditions, I felt fuzzy narcosis symptoms. But if I was working hard, or not breathing efficiently, I got a totally different kind of symptoms more related to CO2. The big difference for me was headaches...

    ???Future of Open Circuit Mixed Gas and Rebreather Diving???

    This has been my experience too, I personally have come to notice a big difference between being narced by the depth, or when it is exertion induced at depth and brought on more by CO2 retention. I have learnt I have to go slow and really control my breathing at depth.

    Question Cave Diving Courses advice

    Following advice from here and elsewhere, I did Intro Cave, and then dived at the Intro level for a year before taking Full Cave. I highly recommend taking this slower route. Full Cave was extremely challenging, but I was so much more comfortable after having a year of intro cave dives under my...

    ???Future of Open Circuit Mixed Gas and Rebreather Diving???

    This may be a stupid question but how long does a rebreather unit last? I mean, how long is the software supported, how long are you able to buy parts for it? Like regulators, do you have to worry about not being able to buy service kits down the line? I know next to nothing about the current...

    That is unreal seeing all those ships run aground together like that. Thanks for the informative post.

    What do you do when the anchor line breaks free?

    Did you and / or your buddy tie off to the wreck thinking you would lose your reel / spool in the process? I am just wondering if you had more of a 'this is an emergency' mindset so the reel doesn't matter, or if you were not expecting the crews to cut your lines from the SMBs after you...

    What do you do when the anchor line breaks free?

    Great write up. Question: Did your buddy use a jersey upline to tie his SMB to the wreck, which if I understand correctly he would then have discarded. Or did he use a different method? I am just curious if he was able to retrieve his line once you surfaced or if he tied it off knowing he would...

    Wales/Swansea area diving?

    I haven't dived any caves in the UK since I got cave certified. I assumed most of them involved dry caving to get to. Do you know what there is in the Wales area for cave diving?

    Wales/Swansea area diving?

    Pembrokeshire is well known for diving if you are able to get out to the West Coast of Wales. Lots of wrecks and beautiful marine life. It is hard to find a charter however. I haven't dived with them yet, but I have been recommended to try: https://pembrokeshireboatcharters.co.uk/diving/ Let...

    How you write deco plan on your slate?

    Same here. I have used the same slate over multiple dives with a different plan on each side and the ink has not run or faded. Duct tape and sharpie was a game changer for me. I used to use a pencil and then try to erase it every time which took forever and made a big mess. Now I can just peel...

    How you write deco plan on your slate?

    I also use a wrist slate with white duct tape on it. I then write it on with a Sharpie. This approach is really easy and allows me to keep my old plans for reference. I write my planned deco schedule, my lost deco gas plan, my maximum Time To Surface, and my minimum gas.

    BP/W for an 11 year old.... did I make a mistake?

    To encourage you with my experience, I bought a BP/W for my ten year old and she absolutely loves it! Compared to a regular bcd it is night and day. Her trim in the water is great, and she only needs a couple of lbs (with a short steel plate) if we are in salt water or using a wetsuit in the...
