    too good to be true- OMS SS Backplate w/ Comfort Harness OMS SS System II < $200

    I've been researching backplate options the past few weeks, and looking at the usual sites to get an idea of what kind of investment I'd be looking at. DGX, Hollis, Dive Rite, etc - it looks like I'd be look at ar least $600 or so. But I always check my LDS, because I want to suppor them. And...

    Covid and diving study?

    I seem to recall that UCSD Med and Scripps Oceanography were doing or planning to do a long-term study on covid and diving. Well, I'm a diver and I just recovered from covid. So I sure wouldn't minding signing up, if I can find it. Anyone remember seeing this late last year? Google finds...

    Invasion vs. Surge?

    What's the difference between a ScubaBoard Invasion and a ScubaBoard Surge? I plan to do the Caribbean next year, and saw both invasions and surges listed for prior years.

    how have "jet" fins evolved since the 80s?

    Digging through the garage a few months ago, and came across my original 1980s (actually 1978 and 1980, I think) "jet fins". One pair from US Divers and one from Sub-Aquatic Systems. Man, they look small. The foot pockets look tiny. The US Divers are only 18" tip to pocket edge, the SAS are...

    New (tech) Black Sea wreck dive site to open in 2023!

    There's a brand new wreck in the Black Sea that could open in 2023! 45°10'43.39″N, 30°55'30.54″E Depth is supposedly around 190 ft. Not being a tech diver, just for grins, could someone help me "plan" a "generic" tech dive for this site? Figure 200 ft for 30 minutes - how would you plan it...

    no need to remove SWIFT transmitter battery?

    I just got my Perdix AI on Friday - it should get its first dives next week. I'm the guy that reads all the manuals cover to cover and... why is there a recommendation to remove the battery from the computer if it won't be used for a while, but no similar recommendation for the transmitter?

    Bald and hoods - need extra insulation?

    I recently took the plunge and shaved my head. I did have thick hair before, just not everywhere up there. So there was plenty of hair to prevent water sloshing around under the hood. I'm trying to figure our what, if anything I need to do to stay warm. Cold-ish water diving - Southern...

    why more than 60-100' of line for a DSMB?

    I've been shopping for a DSMB and spool. I've never needed one, so far, but I know the time will come. Especially with some of the fun currents we get in San Diego kelp. But a few dives ago I was in a current with a new buddy, and his DSMB was very helpful for our safety stop. No current at...

    So conflicted - Perdix AI, or wait and gamble on a Peregrine AI appearing?

    So, I was getting ready to buy a Perdix AI. March 2020. Then COVID happened and I wasn't diving. OK, I says to myself, I'll wait and see how long this lasts. I can always get a Perdix AI from the LDS when I am ready to go diving again. I've already put the cash in an envelope in the safe, in the...

    Camera Tray - grease and/or threadlock?

    I am a new-ish owner of your camera tray and have a few questions. First, I love it - I'm a first time underwater videographer, and I wouldn't be doing this without your tray - a great balance of performance and cost! Second, you might want to put the sticker+grease package on TOP of the tray...

    Shearwater Perdix (AI) and MacDive?

    I'm seriously thinking about a Perdix AI for an after holiday gift for myself. There's nothing really wrong with my current computer, but I think that after 12+ years I deserve a new one. Also, the company is (sorta) gone, there's no long term support, etc. I figure that the Atmos 2 can be a...

    To tether or not to tether

    I'm a very new photographer. I've been diving with a GoPro and the stock GoPro floating grip. Of course that's been painful with trying to handle the camera and a separate light. I just received the Mako 2-handle camera tray from my lovely wife as a birthday present, and I have one question to...

    transport weights in bag, or in BC pouches, or ?

    Where/how do you carry your weights to your dive site? My weight bag (was a birthday present years ago) has finally given up the ghost, should I replace it? It's an older version of this one: XS Scuba Weight Bag and has served me well for 10-12 years or so. I'm trying to decide if I should...

    are all AI transmitters the same? Are any of them the same?

    It’s all in the Subject… Are transmitters all vendor (or even computer model) specific, or are some of them the same device and can be used with dive computers from different vendors? In other words, do (for example) Shearwater transmitters work with Mares computers, Oceanic transmitters with...

    Whatever happened to the Bottom Scratcher and Sand Dollar?

    I was reminded of “the olden days” by another post - my wife and I used to do the 2 and 3 (and once I think 4?) day trips as visitors from Phoenix to San Diego, in the early 80s - probably 78-82 or so. All those trips were done through a single shop in Phoenix, and the only two boats we ever...

    advice for a n00b - GoPro vs Sony Action camera?

    Hope this isn't too basic a question. For a first time underwater video person, which would you recommend? A GoPro Hero or a Sony Action camera? I don't want National Geographic or award winning shots, I just want to share what it's like diving, with friends a family. The video equivalent of...

    post Olivia conditions?

    We'll be arriving in Kona Saturday after Olivia passes through. I'm *guessing* that the runoff from the storm will cause some silting and viz problems for a while? How long is a while? A few days, a week? Of course, for someone coming from "OMG 20 ft viz!! WOOOHOOO!" land, I'm still expecting...

    Suggestion Time for a new SSL cert (Legacy Symantec cert)

    Hi, thanks for SB - my favorite online hangout. Thanks esp for the excellent moderation... I just noticed that the SSL cert is a "legacy Symantec certificate". I only noticed because I typically run Chrome Canary, which is 1-3 months ahead of the stable release. Canary (Chrome v70) has started...
