    WURKKOS DL03 2800 lumens dive light with Green laser

    This is a good question; I just discovered last night that EcoGearFX 18650 cuts out when used in a WURKKOS FC13.

    Suggestion Is it possible to use an AI tool to summarize long threads?

    I am not a prompt engineer -- but it's fun to tinker. The following works with ChatGPT or Grok by pasting the thread root URL once at the obvious place: Retrieve the URL https://scubaboard.com/community/threads/carrying-a-pointer-stick.651536/ The page you have retrieved includes a total...

    Suggestion Is it possible to use an AI tool to summarize long threads?

    Used up my free tokens at Perplexity, so I tried this on ChatGPT 4o: Also…

    Suggestion Is it possible to use an AI tool to summarize long threads?

    Unfortunately, a quick search suggests that Xenforo doesn’t offer a “show whole thread” or “entire thread in printable form” choice, as some forums do. Bummer. So… Then copied the result of that into… Yielding (from perplexity.ai):

    Recommendations Cabo San Lucas late December/early Jan

    Water temperature is usually about 75degF; a full 3mm is usually more than enough. You’ll have a better chance of seeing bigger things out in the corridor than in the usual harbor diving (Pelican Rock, Neptune’s Finger, Land’s End — though Land’s End offers a good chance of seals coming to...

    What certifications would you say are a "must have"?

    I like James from Miami Technical Divers’s take on this.

    20000 lumens monster canister light—WURKKOS Most Powerful Dive Light Yet

    N.B. A 30,000mAh rechargeable Li-ion exceeds FAA and IATA battery limits without specific written permission from the air carrier. ☹️, since I was contemplating ordering at the launch discount.

    WURKKOS DL03 2800 lumens dive light with Green laser

    What is the emitted power of the laser? Can you show pictures of the laser in action in varied conditions? +1 to become a supporter for scubaboard.

    How to convert Garmin PSi/min to Suunto CF/min SAC rate

    …except I’d suggest you want cfm as your final recorded value; it’s uniform regardless of cylinder, it’s the usual (non-metric) unit for RMV, it’s comparable with others…

    How to convert Garmin PSi/min to Suunto CF/min SAC rate

    I made this and taped it into a page in my logbook: After dives I can look up the psi/min in the appropriate tank column, do a rough interpolation as necessary, and record the cf/m with the dive. I also put a little dot to the right of the row, right on this table, which has become an...

    PLBs and DSMBs

    If you mean OceanSignal’s rescueME PLB1, it is only rated “waterproof to 15m”, which is a far cry from dive-rated. If you mean some other product, we’re all curious.

    ResQlink View RLS vs 410 RLS

    450 is almost 8 inches tall (though nicely slim.) Wouldn’t fit in a DryFob, though maybe in a custom tube of some sort. (Is that a pipebomb, or are you just happy to be diving? :eyebrow:)

    PLBs and DSMBs

    Incidentally #2: I see some discussion earlier in the thread about time-to-launch concerns on PLBs. I think these are fair concerns, though for me the net choice is still a PLB. In re. possibly reducing time-to-launch: PLB registration is easy to update (in the US at least) and includes a...

    PLBs and DSMBs

    Incidentally (not sure when the design changed) but the ACR 375 covers both test and activate buttons.

    PLBs and DSMBs

    There are always design/utility tradeoffs, and they are designing for a pretty wide market. We can wish for improvements that align with our needs, but meanwhile we work with what we have. Like @NW Dive Dawg I have a PLB (ACR 375+), mirror, and whistle stuffed into one of @Jaan ’s canisters...

    ResQlink View RLS vs 410 RLS

    (Don’t own either, no stake in the outcome, just thoughts.) Review the manual online to help you decide. IMO, most of what’s on the display is not actionable or more than what’s theoretically available without the display. But. It’s communicated in English, rather than color codes or...
