    Technical Dive Guide Certification in 2025 can we ask for Proof ?

    thats because they've likely done virtually every route on the Coolidge a thousand times and know within a few BAR how much gas theyre going to use and how long they will take to within a few minutes and know every nook and cranny on the boat, what are you wanting them to plan ? theyre...

    Wreck Diver Certification (Blindfolded reel-in)

    following a well laid line is easy- a bad one not so much, personally I thing line laying is a crucial and underrated skill. First class line laying -considering all aspects related to entry and exit is an art bordering on the occult. One of the skills i constantly try to to improve on ive...

    Wreck Diver Certification (Blindfolded reel-in)

    first of all dont beat your self up- try to to look at difficulties/errors on your course as a way of exposing any weakness in you're skill set - then you know what to work on more reeling in through a silt out is not unusual - its rare to get absolute zero vis, maybe in oily water, one...

    Question O2 sensor calibration

    im assuming you check your MV reading at calibration so youll know what RANGE you have and if that range is acceptable. Your mv reading as above are only an example Im assuming as 42mv to 57mv is large difference, so with a top end PO2 of 1.6m, even 10% variation is significant Im not sure...

    Question O2 sensor calibration

    yes of course but I was referencing justins desire to have "A few thousand detailed CCR dive logs with the relevant data could easily generate a 'baseline' profile for what normal sensor data should look like. so yes you can use you're PO2 knowing what it should read at x depth - and you can...

    An age-old question: ways to 60m.

    unfortunately navigating what is accurate or better usually comes in hindsight - how do you determine the correct way if you yourself dont know everything. This seems apparent in this thread, those with lots of diving experience and have been there done that are trying to point out the...

    An age-old question: ways to 60m.

    I think youve got a blind spot here- Im not GUE diver yet I agree with many of the things they do - without trying to belittle you're achievments you need to think about what people are trying to tell you without looking at it through the GUE lens. Heres my take on it - the further you go away...

    Practicing 'emergencies' / 'accidents' underwater - cue / training cards

    thats impressive - not often ive seen that sort of commitment to excellence in a new divier - keep it up -with that mindset my guess is youll eventually head down the technical route I have about 25 cue cards - on one side is the problem the other is the solution -no point practicing the wrong...

    An age-old question: ways to 60m.

    OK so just to clarify you would prefer trimix because it allows you to think more clearly ?not withstanding makes the WOB better ? so you are acknowledging impairment? have you ever been in a high stress situation at depth on air? and yes ive been much deeper than 50m on air, around 75m (thats...
