    CESA from 40ft

    I found confidence building exercises like: 1. swimming underwater in a lap pool to gauge your potential range (full breath and empty breath) 2. Breath holding exerices like static apnea programs on my pc 3. snorkelling, freediving all give you a feel for your non breathing capability...

    Lumba Lumba – Pulau Weh – Serious Safety Concerns – and a dangerous incident

    Fire on board a boat is one of the most dangerous things that can occur. The reactions of people in such a situation are unpredictable at best. Unfortuantely it resulted in injury, but by the sound of it could have been much worse. Was there any explanation to the cause of the engine fire...

    The importer, or anyone for that matter, can use the pdf attachment in the OP to get an approval number for a particular cylinder. You need the engineering drawings and some other info. The difficulty is getting all the info. The importer is the most likely place to get an imported cylinder...

    Mares Dragon AT

    When you say controllable? Its not easy to make fine adjustments with it, but I do use it a fair bit. I normally use the shoulder dump when descending. But once sinking I turn to head down position. Mainly use the lower dump mid dive when I swim up and become a bit positive and find myself...

    Mares Dragon AT

    I have the non AT Dragon and use the large rear dump valve to wash the inside. I unscrew the dump valve, put some water in, replace the dump, swish it around then use the dump valve to empty the water

    Swimming Skills Assessment

    Im not saying you have to be a good swimmer, and hadnt noticed anyone else saying that either. Its personal preference really, and for myself I enjoy diving in challenging conditions, so I stay in shape for these situations. As for not surpassing your limits, the best planning and intentions...

    Swimming Skills Assessment

    Some of the better dives in my wider area are renowned for strong currents and waves. Im not regularly at the pool atm, but can swim 2km in a respectable time. At the beach I can tred water for 3-4 hours while body surfing. The most valuble things for me when diving are general fitness...

    Air integrated wrist computer or not?

    My Suunto Vyper air has been reliable so far in that once its paired up it stays paired for the entire dive. It does however change transmitter codes if the transmitter is activated for long periods and doesnt pair with the wrist unit. The typical scenario where this can occur is after a...

    Scuba Tank Explosion - Myth or Reality?

    One thing to keep in mind for tanks / burst disks is fatigue, not just the maximum pressure exerted on a cylinder. Consider a cylinder with a defect that is undetectable by regular inspection. Metal impurity, incorrrect alloy, incorrect hardness ect. in a part or all of the cylinder. Over...

    Mares Avanti Quattro vs Excel+

    I recently purchased excel+ to replace my 15yo quattro's and have done 20 odd dives in them. They require more strength than the quattro's as they are bigger and stiffer but I find I can propel myself with small kicks with minimal effort. If I kick with long strokes to try to swim fast, they...

    Scuba Tank Explosion - Myth or Reality?

    Tank exploding should only occur if the tank is rusted or cracked. Otherwise the burst disk will go. I keep my tanks on the floor behind the front seats of my car. The lower they are, the cooler. The trunk gets hotter than the floor Ive found especially if you have the windows down half...
