    sump fins?

    Need some sump specific fins... Criteria: SHORT, 1/2 the length regular fins would be ideal. For reference, I have done many sumps with no fins at all. Big feet for cold water rock boots or similar Lightest weight possible. There is no such thing as "trim" when no-mounting in a beachball...

    Scott Boyd

    While his @boydski account was rarely used... If you dove in the Pacific Northwest you have almost assuredly relied on his deep wealth of scuba knowledge. He was a very active wreck explorer, a cave diver, and a talented photographer. His website saw thousands and thousands of hits over the...

    Subterranean 2023

    This was filmed a couple summers ago and recently released in Canada, you can stream it (in Canada only I think) via VPN or it's making the rounds at some of the outdoor film festivals as well. The divers are myself in ARGO (northern Vancouver Island) and Katie Graham in Bisaro Anima (near...

    Crow's Nest Spring (Alberta)

    @girlwithbigtanks and I headed up there with my boat to give it a go back in September. It's a nice site, but you do need a boat to access it due to the rail line. Not a very long cave and tons of sawtoothing. Also (duh) cold at 3 or 4C. The existing line was of course broken, whoever put in...

    Chainsaws in caves?

    @girlwithbigtanks and I went out to check out some leads we were given. This one supposedly requires a chain saw, which isn't a rarity around here... Not sure if we're going back, by the time I'm motivated again this whole hillside will be buried in snow (there was 16ft of snow last year and...

    Lauren Kenyon

    While she wasn't especially active as a diver or on SB, @Lauren Kenyon was very active in our local grotto and canyoneering communities here in the PNW where she recently relocated. She passed away in a tragic accident last month during a canyoneering trip. Although we hadn't been diving...

    InReach diving activations are statistically zero

    I thought this was interesting and expected to see at least a few diving related activations. Perhaps they are logged as "boating" related? https://www.garmin.com/en-US/blog/saved-by-garmin/data-insights-from-10000-garmin-inreach-sos-incidents/

    CCR Cave course duration

    For someone starting cave diving from scratch on CCR... what's the minimum number of instruction days and in-water hours required for CCR cave? (obviously the max is well, a long time) I know my CCR cave crossover was 3 days, but I was already full cave have with hundreds of cave dives over...

    Solved: Still receiving IMs - but want them off

    I thought I had turned IMs off in my profile, under privacy I have "start conversations with you" set to "nobody" Except I still seem to be receiving IMs. I don't want IMs... I will answer people's questions in threads I feel like I have some useful insight about along with everyone else -...

    S.25 Sunderlands

    Apologies for lumping Ireland into "British Isles" but seemed like the closest fit of the available subforums... Are the scuttled S.25 Sunderlands described as "outside of Belfast" divable? Does anyone have any pictures or video or a 3d photogrammetry model of these? Thank you, A flying...

    Ojamo mine petition

    This is not my petition, Ojamo has been closed to the general public for a couple years now (the backstory why is complicated politics). In any case the Finnish Diving Association is trying to take over the lease and operate the site. https://www.petitions.net/diving_in_ojamo_mine

    IPE

    The especially CCR relevant bits are in the paragraph starting with "Castagna et al..." near the end. https://journal.chestnet.org/article/S0012-3692(20)35498-2/pdf Especially for back mounted CL users, assuming they are staying in trim which is always debatable.

    AB/BC cave diving emergency resources

    Not really in contact with many of the Vancouver Island folks diving Wet Dream - also not sure they are diving any of the other possible systems either. Be advised that IUCRR or any other volunteer rescue/recovery diving help is extremely limited. Any assistance is likely to be delayed even...

    Not your momma's cave diving

    Some ongoing projects, some complete, in these mentions here. Article starts on page 44. While he was a cave diver in the past, the author doesn't dive anymore, but found a number of historic paddlewheel wrecks in the shallows to the Yukon River snorkeling in his diving retirement. These are...

    dual voltage motor issue

    So I picked up another shop compressor to run my booster. I has a 3hp 120/240V motor on it. Unfortunately the wiring sticker is worn away so I can't tell if it's jumpered for 120v or jumpered for 240v. The 4 terminals are not labelled at all. How can I tell these apart with a multimeter...
