    “Duty of Care” when taking others on personal vessel, to dive

    You are not legally required to carry O2 unless you are an inspected, commercial vessel and your COI mandates it. If you are a dive professional, then your agency or its insurer may require that you have O2 available when supervising others who are diving. Legally required? Probably not, but...

    Question Travel Pro 30" roller duffel as dive luggage ?

    I have one. It's too big, and the space goes to waste because you hit the airline 50 pound limit before it's anywhere near full. I replaced it with the TravelPro Bold 28" rollaboard, which is better, as long as you choose fins that will fit. The 28" weighs a couple pounds less so you can...

    Question Information wanted on Aruba dive ops

    I dove with Mermaid Dive Center six years ago when we were last there. I would dive with them again. Keep in mind that the diving in Aruba is OK but not fantastic. https://scubaboard.com/community/threads/trip-report-aruba.558068/

    Techniques for boat diving without surface support

    When I dive from an unattended boat, I do so within swimming distance of shoreline that permits a safe exit. In many cases this involves situations where the shoreline is privately owned, not readily accessible by car, or where there are laws/ordinances restricting shore diving. So I dive from...

    Diving off a small tinny tips and advice

    10' is small. I have a 14' one and it's small. Reboarding advice. Take off your kit and weights and tie them to a line you've left trailing from the boat, but leave you fins on. Board over the side. If there's someone aboard then they move to the opposite side and lean back over the gunwale...

    Bright Weights for BP/W

    For local dives without much weight, I use the Mako trim weights on the belt of my BP/W, that attach and detach individually with their own bungee. Otherwise I use a rubber belt. I had a Mako belt for a while until the rubber started to deteriorate, and now I have one with a friction catch...

    Will an older 72 cu. steel tank take a modern K regular valve?

    Quite possibly M18. I encountered an older tank with that thread form once. Amazon has them. No idea what the quality is like. Be sure it truly does fit properly, natch, valve ejection accidents suck. www.amazon.com/TUXING-4500Psi-Scuba-Diving-Valve/dp/B0BLZ2VTQ9

    Do you wear a dive watch? (not computer)

    I have moved towards using a dive watch. On the many shallow dives I make where NDL is simply not a consideration, it is now all I use. On deeper dives I use it in conjunction with a computer.

    Solo Kit setup: the required, redundant, optional, and hell-no items

    45' is an odd depth, sort of in the interregnum between shallow and deep, as it were. Where I dive usually the viz limits practical depth to around 30' at most locations, and 100' is feasible otherwise. Clearly your situation is different. I start bringing redundant air at 60'. Above that...

    Help identify and rebuild US Divers first stage

    I have a Calypso J in active use with 1085 second stages. It does have the newer handwheel for the yoke connection. There was a recall for these first stages related to the valve seat coming loose and sticking to the piston resulting an abrupt and complete loss of air delivery. The fix was to...

    Free diving fins

    I have freediving fins and use them for scuba. They're long. Really long. They won't fit in your dive bag. They won't fit in most luggage. They will get in other people's way on the dive boat. They are even more awkward to try to duck-walk around on the boat or on a dock on, than regular...

    Question Single Wing

    My daughters both have DGX wings and like them. A fact to consider is that DGX changes suppliers and designs from time to time. You get what you get, and it may not be the same thing at all as what was sold as the same product 12 months ago.

    Dive Flag Violations

    It's a mistake made by the dive community in the early days. To make it easier to pass legislation requiring boaters to respect dive flags, the strategy was to propose legislation that posed a burden on both divers and boaters: divers must use the flag, boaters must respect the flag. It is...

    New BPW setup - worry about lift capacity?

    The wing will be fine if you are weighted exactly right. The problem you have is that there is very little reserve buoyancy beyond what you actually need for compensation for wetsuit compression, so that if you are overweighted even a little, you may not be able to reach neutral buoyancy at depth.

    Mantus Marine dive compressor

    For a period of time I had a small, lightweight military surplus compressor. I was unable to get it to work reliably and ended up scrapping it. I have a number of boat projects to do before I can look seriously at a compressor again. I have a Tartan 3800 now that will require significant...

    Sayulita / Puerto Vallarta

    We are traveling to Sayulita in March for a mostly non-diving vacation. I am trying to decide whether it's worth it to bring some gear and book a dive boat for a day or two, and also trying to decide which operator to use and whether to book in advance. I will be traveling with my wife, who...

    Burst disks???

    The whole situation with burst discs is a mess. Yes, they can fail, completely and without warning, well below their design pressure. As pointed out upthread I had this happen on a cylinder with an older valve and burst disc assembly with a single gas outlet drilling, unlike the current...
