The other day while I was doing a Google search for an out-of-print book, "Oxygen Hacker's Companion by Vance Harlow", I came across this list of suggested books for your personal library. I found this blog article about suggested books for your personal library fascinating and thought I would...

Hey Everyone! I recently did my TDI Intro to Tech in the Gilis and I'm planning to visit Thailand in Dec '22 to do a few tech courses - TDI AN+Helitrox, followed by TDI Trimix. I believe it will take me 8-10 days to work through both of these courses, so am planning for a 12-14 day trip. The...

I have been playing with developing bailout plans for CCR dives. The approach I was trained on is to calculate gas required for safe ascent to surface taking into account all deco obligations from the worst possible point of the dive (typically the end of the bottom part of the dive). I would...

I'm sure this has been talked about many times before, but I would really like to compile some information before I go out and drop 2-3k on a drysuit. I am currently looking for a drysuit of moderate price but I really don't know anything about them. I am someone who is big and tall ( 350 -...

I think I have this in the correct place. I have a Dive Rite O2 Deco Regulator with a Mini-SPG in PSI with a Luxfer Aluminum 40cf Cylinder for sale. I purchased the set from Dive Gear Express in late 2017. The tank is still in hydro and has about 2800 lbs of O2 currently in it. I last used...

This is purely for fun... So much diving gear, especially that branded to be technical diving gear, is dark or black. I now read the word sometimes as technicool (similar to the tactical --> tacticool boom over the past two decades with military gear). Why not bring some color to your next reef...

Hello divers, I think a lot about my future diving and how to proceed into the level I want to and would like to brainstorm a bit my ideas with you to have another insight, opinions and maybe recommendations :-) First, bit about my diving history, skills and interest: I did my OWD + basic...

Hi all, I'm from a start-up developing bio-inspired materials tech for the diving and water-sports industry. I'm doing some background research into rebreathers and was hoping to get the community's opinion on: - Why you initially switched to rebreather diving? ( e.g..... for the experience...

Hi All, I am beginning my Tech Diving in the next 6 months, I am currently facing the choice of Side-mount vs Back-mount. I would like to get some basic training before my TDI AN&DP to familiarise myself with my chosen setup and as such am leaning towards Side-mount as its a common course...

Hello! I am fairly new to diving and was hoping you all with far more experience and knowledge would be able to help me out. I have a few questions. One is, which company has better quality gear and warranty should anything happen when it comes to BP/W, OMS or Halcyon Dive Systems? I have been...
