How many fatal shark attacks within a radius of say 300 km of the ocean location you are about to dive would it take to deter you from diving? Pick the one that best describes your choice. I'm interested to get some idea of the risks divers are typically prepared to take in this regard. Assume...

I understand this forum is to discuss recent incidents and fatalities associated with diving. In this case, the diver was fatally attacked by a shark likely to be a white pointer...

Did you learn any new skills? What important knowledge did you learn? What should you learn? Did you consider this course worthwhile?

There has been some recent discussion regarding ocean 'swim throughs' and 'caverns' in some areas. Where I live we have thousands ranging from a few metres to over 20 m. Assuming: There is only one clear path and no chance of getting lost; The floor is course sand that won't silt even with...

This thread has vanished. Can the forum admin explain what has happened.

Even in caves with multiple openings, sometimes called swim throughs. Sere picture below. Why not? We have a lot of them over here and some of my favourite diving is within these caves.

Went out to day on a chartered dive boat. I met up with a past dive buddy who I'd lost contact with. I thought he'd given up diving. He had stopped for a while and then got sick and was just starting to get back into diving. We buddied up. He was chasing crayfish and I was taking photos. First...

The SDI solo course book recommends using the rule of thirds as a way of determining the requirements for the redundant air supply when diving solo. This is the same recommendation for the reserve supply when diving with a buddy. In one case you are using the rule of thirds for a single diver...

Just booked onto the SDI solo diver course. I rang four different dive shops and got varying stories. Dive shop 1. They do the PADI solo diver course. Lots of messing around trying to get on a course. Cost AUD $350 Combined with side mount course. Course done over 5 days. Presumably less if...

Interested to hear ways to minimise stirring up the sand and silt when lifting off the bottom.

Most of the dives I do are from a charter boat. Our dive plan is to jump in and explore the reef structures then get to the surface with 50 b in the tank and back on the boat within an hour. I'm interested to hear some of the gas planning and navigation techniques people use for this kind of...

How low would you draw down your main 12L air cylinder at 232 b diving solo with a 2.7L pony bottle at 200 b diving in the ocean. Without the spare air you'd normally surface with 50 b.

I've noticed browsing through forum threads on the recommended Nitrox limits, the question of how close you can sail to the MOD limits or time exposure limits based on PPO2 (partial pressure of oxygen) limits of 1.4 or 1.6 b often surfaces (pun intended). How conservative are the limits? How...

Do you find the thicker wetsuit or wearing extra layers under a suit makes a lot of difference in keeping you warm? For those who dive in cold water temperatures, which is better, a thick well fitting wetsuit or a drysuit? Does putting extra layers on under the drysuit make much difference...

If you stay at or below the maximum operating depth (MOD) for a nitrox mix more than 45 minutes then you can get oxygen toxicity. I'm interested to know how many divers venture below the MOD for shorter periods of time. If you do dive below MOD, how do you determine when it is time to ascend to...

After much thought I finally placed the order for the camera housing with Recsea. The camera will come this week. I have a SS YS-01 strobe and Sola 1200 photo light. Up to now I've used an Olympus Tough TG-810. In general I liked the camera and was able to get some nice photos while recently in...

When I look at the data that was downloaded to the Suunto DM4 Dive Manager, I noticed that the tank pressure is not not transferred through to DM4. Have I missed something here? Is there a way to get this data to appear?

I recently did the advanced adventurer course through SSI and was advised in very strong terms that you should never get less than ten minutes to the no decompression limit on your computer. What do you think?

I recently bought a Scubapro Nova Scotia wetsuit and am wondering what to do about the neck seal. On the legs and arms you roll the inside flap of the wetsuit so the slick surface is in contact with skin. The neck seal also has an inner and out flap. Do you roll the inner flap under like you do...

How do you stay orientated while night diving? I've been doing a few dives along jetties including a ship loading jetty. Visibility is poor at say 3-4 m. I suspect the steel pylons are also affecting the magnet. It has amazed me how quickly I can become completely disorientated. I've got a...
