    Suggestions for Diver Tool Kit?

    Hi @csiems, sounds like a great gift idea! I completely agree with your thought on buying something of better quality than a flimsy kit. Personally, I have a medium-large tool bag for mine that I've maxed out. If you are starting from the ground up, buy larger than what you think he needs so he...

    Advice to get lower SAC?

    Hi Clayton, the short of it is, you may find it better to opt for larger tanks or bring more gas with you. No need to put so much stock into your gas consumption rate. However, this was a question I got asked frequently and wrote an article on how you can improve your consumption here on page...

    Helium reclamation/recovery -- does it exist?

    Helium has gone up 25-30% over the past two years for us in Hawai'i. :cry:

    New divers need equipment help.

    Hi @GuysDigDirt, kudos for your interest in taking the next step! In my circles I get asked all the time about tips on buying dive gear, so I wrote up an article with my tips and advice for our University of Hawaii Newsletter. You can check it out here on page 4: December 2017. Similar to what...

    Help me understand rebreather progression please ...

    It has become a tradition of mine to watch Mike Mullane's "Normalization of Deviance" talk before every mesophotic/rebreather expedition I do. I highly recommend it!

    Aloha Jessica, I just published an article in our University of Hawaii magazine on "How to Properly Shop for Dive Gear." I explain some of the questions that folks should be asking themselves before buying equipment (which might be remedial info to your experience). At the end on page 7 I listed...

    First time vacationing to Hawaii.....suggestions please?

    Aloha Eric, I live in Hilo on Hawai'i (aka "Big Island"). The manta dive is in Kona so you would want to come to our island for that. Hawai'i has a very diverse amount of attractions such as our famous Kona coffee sampling/tours/tasting, great dining, awesome waterfalls, hikes, the best night...

    Setting up harness for Deep6 bp/w

    Looks like you got quite a few tips and videos on how to string the harness. For their polyurathane coated nylon webbing, it can be tricky to weave, especially the crotch strap! I found spraying it with a little bit of water helps to reduce the friction. Imagine you're looking at the bottom of...

    Where to find quality used equipment?

    From my experience, ScubaBoard's Classifieds are probably your best bet. Craigslist and Ebay can be very challenging if you don't know the correct questions to ask, or if the seller doesn't know the full history of the gear (often times I've seen people selling equipment that aren't divers)...

    Info Scuba Cylinder Valve Installation

    Thank you for sharing @Akimbo! Can you tell us more about that last vice with the ratchet strap? At my previous establishment we had the V-shaped vice from Global Scuba Manufacturing. Is this the same one?

    Backup Computer for Rebreather Divers

    Our mesophotic team probably has over 500 collective hours using the NERD and have had 1 failure in that time from a flooded battery compartment. Since the NERD 2 is rechargeable, hopefully that failure point will be eliminated in the future.

    Backup Computer for Rebreather Divers

    If you have the budget for it, Shearwater's NERD would satisfy both the loop and deco monitoring concerns. I love using it and looking forward to upgrading to the NERD 2. I also use a standalone too but that's because I encounter more deco time than most. I have plenty of dives just using the...

    Scientific drilling and climate change

    Nice! Happy to see such large Porites (lobata?) that's healthy. Our massive ones in Kona were killed in the 2015 El Nino bleaching event :(.

    Where to spend a dive vacation?

    Aloha! I live on Hawai'i Island (AKA the "Big Island"). Given your choices I'd recommend the Big Island for sure. I've dove most of the main Hawaiian Islands and Hawai'i is still my favorite. Plus we have the world famous manta dive as @diversteve mentioned. We also have some of the best coffee...
