    single or doubles BPW?

    A lot depends on where you dive. Absolutely best thing to do is talk to the instructor you are planning to do fundies with. He can help you out with gear and equipment choices. Even better why not rent some gear for your course before you lay down the cash. Whilst Halcyon is popular in the...

    Formula for estimating wing size?

    30lbs for single tank ali tanks, wetsuit and warmer weather. 40lbs for single tank, steel, drysuit and cold weather. Also for Single tank tech (twin valve or carrying stage for redundancy). 45lbs for tech 1 and tech 2 level (max 3 Ali stages). Cold or warm. 60lbs for when you start getting...

    XTX50 or 100

    I prefer the XTX 50 to the XTX 100. The only difference is in the materials. 50 is mostly plastic. It still has venturi and adjustment.

    Will PADI Recognize SSI specialties (Perfect Bouyancy)

    The fact you can't use an SSI speciality for PADI Master Diver is exactly why it exists in the first place. It's means that you only take PADI course in order to get the certification.

    Long hose and octo with necklace for rec diving

    Long hose works great in the recreational environment. I would suggest getting some training from someone who knows how to use it at a bare minimum. Ideally a the fundies course or similar. The main danger is that if you are with an inexperienced buddy they might use the length to get away from...

    Allergies and Congestion?

    I suffer from Polyps and Allergies causing me to often have a stuffy nose. However it is limited to my nose and not my actual sinuses. I take Flixanase and Antihistamine and don't have any problems as long as I keep on my medication. However if your sinuses are feeling bad and you are...

    Deepblu COSMIQ+ users' experiences please

    I've got one and its a pile of s**t. Wouldn't charge the first time I went to use it. Wouldn't sync. Absolute s**t.

    Intermediate diver choosing between 4 BCDs!

    Also should probably mention that a for harness and Ali back plate is also easy to travel with.

    More information will likely be forthcoming but a Technical Diver has died during a guided technical dive on Rebreather in Ras Mohammed yesterday on 8th December. Speaking to the guide there was no fault with the unit so some kind medical problem.

    Intermediate diver choosing between 4 BCDs!

    You should have a small d ring on the back centre line. If you order a 1" crotch strap you can thread it through here the other part goes where the belt clip is. On my friends we changed the plastic buckle to a more durable steel weight belt buckle and removed the chest strap as it wasn't really...

    Intermediate diver choosing between 4 BCDs!

    If you want to make it lighter why not ditch the pockets and wear a weight belt? Personally I think the lite hawk is ok and zeagle too. However I would have to add a crotch strap to either of them. Also I think for warn water with single tank and 5mm wetsuit you could get away without...

    Donating the "primary" regulator

    Absolutely agree woth Bob. There's no right answer. Just do what you are going to do and make sure you know and practice your drills. If you want to use an octo in the traditional sense it's not really problem for me and as long as you know how to use it.

    All this talk about sharks!

    Or there's the old black and water striped wetsuits that the surfers use. I think there is some research behind those

    Any review of OMS Airstream & OMS Evoque?

    Why not just stick to Apeks or Scubapro? I dont see a reason to take a risk. Btw I have a set of OMS R600 regulators. No longer able to get parts for them to service so they are just being used on Drysuit bottles now. Such a waste.

    Donating the "primary" regulator

    Everything has advantages and disadvantages. No one set up is right for every situation. The best thing to do is know the strengths and weaknesses of you equipment. Whatever emergency procedure you select make a habit of practicing it with you buddy or team. Try to practice a skill each dive...

    Maximum SAC for Tech diving?

    This is the answer. SAC rate is rather irrelevant to be honest. As when you do your proper decompression course you will be taught how to plan your dive taking into account depth, time and SAC rate. So having a high SAC rate will mean you carry more gas but if your SAC rate is high because you...
