    Looking for a sponge scientist

    Hi all - I've exhausted all of my local (Hawaii) resources. I have an unusual sponge. For those that don't dive in Hawaii, most of our sponges are encrusting sponges. This one is more like a rope sponge like you might find in the Caribbean. From the sticky at the top of the forum: (1) How...

    Black Pebble Beach dive

    Here's some video from yesterday's dive at Black Pebble Beach - South Kona, HI. It was my 1000th rebreather dive, and it was a very nice dive with several harems of Flame Wrasse, several harems of Psychedelic Wrasse, a dozen Tinker's Butterflies, a Bandit Angelfish, a male Whitley's Boxfish, a...

    Surface markers - taller?

    Hey Tobin - Here's a request for taller (1.5M/5ft +) surface markers based on your current design (which is inspired, btw). Did some drifting deco in high seas recently and the smaller SMBs were a bit short. Being a NAUI Tech guy both yellow (follow me) and red (send gas) would be...

    New 1M SMB

    The new 1M SMB is very clever. What a great design! In NAUI Tech land we use color-coded SMBs to indicate to the support crew whether or not we are doing drifting deco or if we have an emergency. So a yellow version would be a very welcome addition to my pocket :D

    Intake air dryer?

    I'm seeking opinions - my brother-in-law is trying to talk me into putting some sort of air dryer on the intake side of my SA-6. He suggested a refrigerated air dryer, but the prices are, um, painful. So we started kicking around the idea of using a desiccant cannister, much like you would...

    Port options for a Sigma 12-24 wide-angle lens?

    Hi there - I'm not the photographer in the family, but She Who Is is upgrading to shooting her spiffy new D200 under water. I've been assigned the task of figuring out which housing and ports to get. One question which I have not been able to answer is if there is a port which will work...

    Limit of 5 certifying agencies?

    There appears to be a limit of 5 certifying agencies in the Dive Info part of the user profile. I hold certifications from PADI, SDI, TDI, AAUS, NAUI and DAN ... is there a reason there's a limit of 5? Can it be raised? This is not a huge issue, by the way. TIA -

    Nitrox and/or O2 fills in / near Cabo San Lucas?

    My wife and I are considering heading to Cabo San Lucas the week before DEMA. I've done some web searches and so far haven't turned up anything about dive operators with either Nitrox (open circuit) or O2 (closed circuit). I know about Cortez Club up in La Paz, but we'd be going with...

    Lake Kona

    *Sigh* -- it's Lake Kona out there, and I'm leaving for a month tomorrow morning (San Diego, Dublin Ireland(!) and Nashville). Oh well -- had a couple of good dives yesterday. Found the Dragon moray at Eel Cove :dazzler1: Also bid farewell to what's left of my 7mm Pinnacle wetsuit...

    NITROX tank & loose weight rentals in Monterey

    My wife and I are going to be in Monterey the week after next, diving at Pt. Lobos and (maybe) Monastery. Does anyone have a recommendation about who to rent nitrox tanks from? Al80s fine, as are steels (neither of us is bringing doubles gear). It looks like Monterey Bay Dive Center has...

    Suggestion Two additional certification agencies

    Would it be possible to add two more certification agencies to the "dive info" part of the profile? I'm thinking specifically of DAN (e.g., I have O2 Provider and AED training from them) and AAUS (American Academy of Underwater Sciences) for those of us that are (occasional, in my case)...

    Rumor: deep airplane wreck off Maui: true?

    I've heard a rumor that there's an airplane wreck off of Maui (south Maui??) that's relatively deep (190-ish). Anyone know anything about it?

    Wizard Publications' Guidebooks

    SInce it seems to be common to mention Wizard Publications guidebooks to Kauai, The Big Island, Maui and Oahu, perhaps some moderator (hi, justleesa ;)) would consider making this note sticky. The guidebooks are very, very good and chock full of useful information.

    Suggestion Adding DAN as a training agency?

    For "Settings & Options - Dive Info" can we add DAN as a training agency? My wife and I both hold a couple of DAN diving-related certifications (O2 and AED, but DAN has lots of others)

    Who else was down at 2 Step yesterday?

    I have a sneaking suspicion that there were more SBers down at 2 Step (Place of Refuge) yesterday (sunday 15 Aug). I saw Ira and Carol and Rudy and his wife. I was the guy in doubles showing my newly certified friends around. (used the doubles because said friends were borrowing my singles...

    Poseidon Cyclon hose adapters?

    Can anyone point me at an adapter to be able to use "standard" LP regulator hoses on a Poseidon Cyclon regulator? I was made a present of one and would like to use a different length hose. Failing that, can anyone point me at someone who will make a custom-length hose for same? I did a...

    Forum subscription broken?

    Is the "subscribe to forum" feature broken? Attempts to do so lead me to the "subscribe to thread" page, and no joy can be had. Not sure what I might be doing wrong to provoke this, or if it's just busted... tia -
