Hi all, I have always had a bit of difficulty with equalizing my left ear, which often occurs in the middle of a dive. I also cave dive which as you can imagine is sometimes a problem, as ascending is not always an option as you are at the mercy of the contours of the cave and have to descend...

Hey all, I am interested in understanding how to better calculate the volume of gas in my cave filled LP108s. This seems particularly important when diving with a team with HP tanks. The simple calculation to do this is 108/2400*3600*2 which gives you 324cuft of gas. However, as I understand...

Hey all, I know there's a few past threads on this topic but they all often center on options for IPhones. Other than Multi-Deco, I was curious if there were other apps out there that you would recommend or recommend to stay away from for android. Also, I downloaded a free app, TechDeco, does...

I'm looking to buy a deco reg and had a couple questions about the Hog D1X 1st stage along with the Classic 2.0 second stage. 1. Are these regs ok to be used with 100% O2 out of the box? 2. I can't find green purge covers (for deco) for the Classic 2.0 second stage but have found a couple of...

I've been thinking of getting into sidemount and was curious about the different set ups available. I was at Cave Adventurers yesterday and of course they were pushing the Katana 2. I'd love to hear others' experiences with the various systems out there. What do you like? What don't you like...

Has anyone used the Deep 6 can light? Currently listed on their website for $499 with original price of $1,199 (discounted 58%?). Was curious how these compare to other can lights out there, UWLD, Halcyon, LM, Dive Rite, etc. Here's the link: Deep6 Backmount Canister Light

Hey all, I lost a backup light today at Ginnie. Went in the Ear, did a main line dive to about 800 ft, and exited back through the Ear. When I got out I noticed I had a bolt snap without a light. The backup light is LED, black in color, with Expedition written/engraved on it from the...

Hey Shearwater, Recently purchased one of your Perdix AI dive computers and I am loving it so far. One thing I noticed on a dive though is that the Surface Air Consumption/SAC calculation is in PSI/minute. Have y'all ever thought about adding a feature to allow people to put in their cylinder...

Selling a TUSA RS130 (R100 1st stage and S30 2nd stage) with Mares Viper Brigade Octo and Aeris SPG. This regulator set has 75ish dives on it. It has not been used or serviced in quite awhile so whoever buys this reg should get it serviced. However, I did jump in the pool with it recently and...

Hey all, looking to buy a Scubapro S600 or G250V second stage if anyone is interested in selling one. Trying to complete a single tank setup that I picked up recently and I want to have the same or similar backup reg as the primary. - Ryan

I've recently moved back down to FL after being away for 7ish yrs and am slowly getting back into cavern/cave diving. Awhile back I accidentally washed my Intro to Cave with Doubles card through NACD which ruined the card and made it unreadable. This is when they were issuing this card as a...

I'm interested in what gradient factor settings everyone is running and why? Does the type of dive you're doing affect your settings (e.g., cold vs. warm water, technical vs. recreational, clear vs. silty, other)? I've heard everyone is all over the map with regard to the settings they are using...

Selling a Large Scubapro Knighthawk Backinflate BCD with Air2 octo/inflator combo and integrated weight pockets. This BCD has never been dived except once by me recently in the pool to ensure it was working properly, which it was. BCD was thoroughly rinsed after pool dive. I recommend whoever...

I have a TUSA R-100 first stage regulator (RS-130 when paired with second stage) from around the 2008 era. Does anyone know where I can find a DIN conversion kit for this regulator. Would love to convert this reg to DIN. Also, do they make rebuild kits for the first and second stage of this...

I have a TLS 350 size Medium suit that I bought for $500. It's an older suit.It has brand new uncut wrist and neck seals put on by Steve Gamble for $150 and the zipper looks good but I believe it is leaking from the inflator which needs some work or replacing. It has turbo soles on it that fit...

I'll be moving to Ohio for graduate school this fall and was tossing the idea around of trying out some ice diving while I'm up there. Looking online and talking to others in the north who do ice dive it sounds like being on a tether with a support person above is the norm... which sounds...

I'll be moving to Akron Ohio from Florida for grad school in the fall what diving is in the area and whos there to dive with? A little about me: I do some cave diving, am a dive master though not current, have a bit over 300 dives etc.
