    Tec Diving Journey / Seeking Advice

    Don't dive deep air. Deep air is stupid. Are you doing your deco on air as well? You are struggling because your initial instruction was lacking. Good for you to recognize that your skills aren't where they need to be. That attitude will keep you alive. Do more shallow dives to get your trim...

    Review Diving the Avelo System

    I can do that with just a backplate and wing and doesn't need an ill-thought out, cludgy system that is chock full of failure points. This is just throwing over-priced equipment at a skills problem. If someone needs this to maintain neutral at 105' in a standard BC, then they shouldn't be down...

    Helium drysuit bouyancy

    We learned that plugging in a lean mix in 40F water means that the only realistic choice is to thumb the dive at the dock.

    Bell Island Wrecks, Newfoundland

    In Ireland. Too bad. I had to cancel my last trip there in 2022 and I've been wanting to get back.

    Helium drysuit bouyancy

    Yeah, 40f and a trimix suit gas isn't a good thing. My buddy he arrived at the site and we found out he forgot his suit gas cylinder. 80' max dive, 60' average. All he had was the trimix in his 104s. No deco needed and so no 50% was brought to use. So we thought "what the hell? How bad can it be...

    Helium drysuit bouyancy

    It is interesting to see that some say they have used a helium mixture in their drysuit. What temps are you doing this with? I'm guessing 70F-ish. I dove with a guy who plugged into an 18/35 in a 40F lake and he got so cold that within 15 minutes he couldn't navigate his way around a site he...

    Dive Talk Go Rebreather

    That is just total nonsense as anyone with a few hundred or so would know.

    Half-packing sorb -- Possible, or deadly?

    It's not. It's done all the time by a lot of divers.

    Mask on forehead=panic. Where did this mask signal originate?

    Happens a lot in cold weather. When diving below freezing temps the guideline is to not breathe through your reg on the surface as it may freeflow. I've seen it, mostly on Scubapros.

    Yongala in April

    That's quite sad considering what a great dive it is.

    Yongala in April

    I went to the website and I was surprised that Paul Crocombe is still doing the diving thing. I would have thought he retired ages ago. He did my NAUI Instructor crossover in Townsville back in 1996.

    Yongala in April

    I will be in Townsville April 17 to 22 (Thurs to Tues). I would like to get back out to the Yongala, preferably a day trip but I would consider a weekend Live aboard. It's been over 15 years since I've been in the area. Who is still around that does these dives? I found one operator out of Ayr...

    Which do you think is less dangerous at 160ft? Open-circuit air or CCR trimix?

    It provides evidence that 80% of divers have problems. That's a pretty effing large percentage that are going to be messed up on air at that depth. Thanks for adding to the proof that deep air is stupid.

    ISC Meg Modifications

    Must be a cave thing. I'm an open water shipwreck type. After 13 years on a KISS Classic it took me 2 years to be able to just let the Meg do its' thing and not micro manage it during the dive. Life became easier once I let it do what it was built to do.

    Assembling Tiny Doubles

    I just knew that at some point a bungee wing would be involved.

    Which do you think is less dangerous at 160ft? Open-circuit air or CCR trimix?

    I'm pointing out the flaw in the exercise.

    Which do you think is less dangerous at 160ft? Open-circuit air or CCR trimix?

    Unless you start ascending, especially in the shallows, then it's a lot quicker than you think it would be.

    Aquatek Scuba. Edmonton

    Looks like a pretty beefy motor on it. Probably gets people to places real quick.

    Looking for dive shops and opportunities in Halifax and Sydney Nova Scotia

    If you are in each area for just a day, nobody does 3 dives a day there. I've never dove with East Coast Scuba but they seem pretty good. For the Sydney area, Harv Morash out of Louisburg is as solid as they come. See if he can fit you in when you are up there. https://www.louisbourgscuba.com/
