    DeepBlue - A dive planning toolbox

    Cool project, I second the idea of trying to implement some of the alternative/experimental algorithms to offer something unique. Alternatively, it's a different project, but if you ever feel like making a non-cloud, open source dive log software with highly configurable input fields that...

    Closed Cheap Men's undergarment

    Wool socks + good wicking base layer + fleece bottoms and tops from the thrift store layered as needed. Really good merino wool base layers cost money but last a long time and can be used for other outdoor sports to help justify the purchase. Other warm wicking technical fabric base layers work...

    Question Maximizing pool training for under $500 without ongoing costs?

    ABSOLUTELY good idea - building snorkel/freedive skills in the pool will make you a better diver. More people should approach it this way. You can practice a lot of the skills (like mask remove/replace, kicking technique, ditching weight, etc.) freediving in a pool then go into the certification...

    Equipment Fatality: Trapped cleaning city tank - Blair, Wisconsin

    If this went down as reported, which it may well have, this is an incident we can actually learn from. Headline makes it sound like he got sucked into something, but the article describes him being unable to disentangle himself from his cleaning tool due to hypothermia. It's not that hard to...

    Review Seaskin Nova drysuit

    I would consider building enough muscle (or losing enough weight) to substantially change suit fit a big enough accomplishment to justify the cost of having the suit altered. Get the suit that fits you now, and when/if you need it changed get it modified.

    I want a new primary light, two backup lights, and two video lights. What's the smart move?

    What are your goals for the video lights? Are you filming fish close up or trying to illuminate a huge cave room? It's fine to have separate backup and video lights, backups can be simple sub-$100 single-18650 lights so you can have plenty of them. Hog Safety 1100 Dive Light Some of the...

    Shearwater and the Poseidon Solid State Sensor

    I assume Shearwater's stance is more like "zero public announcement so far" rather than "zero interest". I have specifically asked several SW people and always gotten silence rather than "no". But beyond that I have no further inside information. There are many challenges beyond the engineering...

    What would you want in a $2500 regulator?

    I wouldn't want anything more than a limited edition color that shows I spent $2500 on a regulator

    Filament Choice

    Generally parts are weakest along layer lines (perfect layer bonding is hard) and when they fail they split between layers. Consider the forces that will be applied to your part in use and try to print them in a way that those forces aren't splitting layers apart. The other thing you want to...

    Filament Choice

    PETG is the best "common" filament for general underwater applications. It's easy to work with, recyclable, and achieves excellent strength and layer bonding. ABS used to be king for this, it's alright, but printing stronger watertight parts is just easier with modern PETG offerings. Consider...

    Bonaire once-in-a-lifetime vacation

    If you're looking for luxury with technical diving support, Area9 might be worth a look despite their stupid branding. Last I heard they were setting up to offer high-end accommodations plus tech gear rentals. I don't know if they're fully operational yet, or if they are just a dive shop without...

    Info MIT Tech Review Article: Deep Diving on Hydrogen

    H is not feasible to use shallower than that. It's an extreme option to enable extreme dives. The reason is that H becomes a bit safer (less explosive) in gas mixes with less than ~4% O2. You can't dive such a mix shallow.

    Question Depreciation of used equipment

    Good question, I don't have a specific percentage for you, but if you use Ebay's advanced search you can look at sold prices and calculate something. Cameras are particularly hard on this front (even vs other dive gear) because new versions are constantly coming out.

    Question Deserved DCS hit even with deco cleared due to high exertion during the dive?

    Good writeup. Sounds like a number of small factors added up. Dehydration is a major contributor, well recognized as a root cause in many DCS cases. Being cold at depth then very warm (and exerting yourself) on the surface post-dive would have contributed as well. Both things can increase the...

    Advice on attaching various equipment to BP/wing setup

    - Glue on big wetsuit pockets or get tech shorts with big pockets. Pockets should be huge and velcro flap style. - The "how to tie a boltsnap" video tutorial is good - DSMB+Spool go in left pocket, spare mask and wetnotes go in right pocket (if you want to follow GUE's well-thought-out standad...
