Unless you know for a fact you are going to need to open your eyes underwater, there is no reason not to wear contacts. I have used both and prefer the contacts.

Sharks are not attracted to menstruation blood because it is human blood, and not something that sharks would ordinarily key in on. The other elements of the discharge may be more interesting to a shark for curiosity sake, however there simply is not enough of any of it to be of any interest...

I remember waaaay back in the late 70s or early 80s having a disagreement with my brother over masks. I had the oval orange rubber Ron Taylor mask, my brother a rectangular mask with nose pockets and side plates. The best part of his mask was you could take 5 pounds off your belt...that thing...

For the most part I agree. If you drop your head below your feet often on a dive though, say to look in holes and such a crotch strap can keep the bc from falling down around your head. As for sizing, some people just don't fit the model. For me, sizing of the cummerbund and shoulder straps...

I keep trying to give you the benefit of the doubt, but you repeatedly post in a manner that is more conducive to picking a fight as opposed to trying to have a real discussion. I suspect that you are correct, the overall tone of SB is divers who are passionate in their pursuit of...

Lost mine once, in current at night watching a large jelly floating in my light heading for me. Just as I was about to drop under it another diver past me and in the process kicked me right in the face. Managed to catch the strap by my pinky finger, so it wasn't strictly lost, which would have...

I don't have a problem with it provided the following criteria are met: 1- The guide is fully certified to be leading untrained divers through overhead environments. Not someone who is at the bare minimum requirements for DM or Instructor, but someone who actually knows WTF they are...

General thoughts...mostly that I do not know enough about it. I would speculate that it would be better to evacuate the diver to a real facility rather than try remcompression in the water. Where I dive the CG is never far away via helicopter. 100% O2 until they can get them to a stable...

We are not disagreeing. I am just not comfortable in my knowledge of what is qualified, and what is not, and this is my process of figuring that out. The more I learn of the AAUS program the less intimdating it sounds. Speaking only for myself I would embrace the opportunity.

I was operating on the assumption that the medical requirements might exclude alot of people who are otherwise healthy enough to dive. If we are discussing general health I absolutely agree, but if we were talking about having divers who are physically fit to...say... military standards than I...

Sorry for the multiple posts. I have just reviewed what I felt were the pertinent tests and requirements for an AAUS science diver certification. Most of the in water tests I had to do in order to pass the exams to get into the aquarium. The only one I did not do was in water mouth to mouth...

Yeah, gotta say that was a silly argument. I am sure that I could find commercial divers who spend all their bottom time with no fins, "walking around", who might be short on bouyancy skills. However I should expect someone with that profession to be able to recognize shortcomings, and work hard...

Jumping in a little late here and short on time, I will probably post more on this later. The aquarium I volunteer at just revamped their diver program and changed some things. They are now taking their cues from OSHA and science diving programs, I suppose that means AAUS. The limitiations I...

In addition to this I would add the following: Firstly, we know so much more about sharks now. Yes if you are floating in a raft in tropical waters you will undoubtedly see sharks, but that does not mean you are on their menu. Many people in the past, and still to this day assume anytime they...

It is not the knife you should be looking at, but the way the sheath holds onto it. Many knives come with some sort of gimmicky sheath and when you reach for it, it won't be there. I like a blunt tip myself, it needs to have a thick blade and the tang should run all the way through the handle...

+1. Most shark attacks occur in low vis turbid water and are a case where the shark has to make a split second decision about whether a hand or foot is food or not. Divers are very large noisy beasts that will scare most sharks. Most attacks on divers are by nurse sharks, because the diver...

Sorry for the confusion, yes I was agreeing with your take on the article. Absolutely, DAN has tons of credibility here. I think that pulling and isolating certain stats in the way I read the article to have done is incorrect. I would ask what led to the OOG. By recovering the body we could...

A slap strap, or neoprene mask strap. Super comfortable and customizable.

Ya beat me to it. The author is not that good at extrapolating information from statistics and falls into some common traps. His example just drives that point home. I should think drowning (running out of air) accounts for a considerable number of diving fatalities, but what is causing divers...

Walls are pretty aptly named, it is a more or less vertical section of coral or rock, and you drift or swim along it. Some have "hard bottoms" that you can see, others maybe be 1000's of feet below you. Some have bad currents and others not so much. I haven't dove there so I don't know the...
