So here's the thing with dry suits and buoyancy... If you are properly weighted then you should be neutral with just enough air in the suit to provide adequate insulation (it is not just the undergarment that provides insulation, but the air that it traps, as well) and avoid the squeeze. As you...

I'm a bit new to Scubaboard, but not to scuba. I've noticed that there are a lot of acronyms, many of them common in the world of scuba, but a few that seem to be specific to Scubaboard (or scuba-related forums), and I've seen a few people ask what specific acronyms mean. So, I thought I'd...

The zip tie trick usually works, but you need to know to twist, which the OOA diver may not know (no guarantee that it is YOUR buddy that is OOA). And sometimes, the zip ties become near indestructible at the wrong moment. In my experience, there are divers that, when they run out of air...

I purchased a new Suunto Solution computer when they first came out. A couple years later, I got a new Suunto EON Lux. Shortly after that, the Solution conked out on me in the middle of a dive (120 feet deep on a shipwreck in Lake Superior). Fortunately, I had the EON as well. Anyhow. When...

I believe PADI requires a sidemount instructor to have a minimum of 10 dives if they take a sidemount instructor course or a minimum of 20 sidemount dives in open water and a certification in sidemount (or equivalent from another agency) if applying to teach the sidemount course without having...

Which is exactly what I thought as well, and oddly enough, nothing I found answers that particular question (the beam question, anyway). I only see that it is "focusable". I was also talking to a friend that uses a Halcyon HID and he said you don't really focus so much as fine tune. And yet...

How tight of a beam does it make? How much adjustment is there to beam width? What are the dimensions of the canister? How old is the light?

1. Does the light come with the handle? 2. Is the light constant or does the light dim as the battery discharges, or does the light step down when the battery reaches a certain point? 3. Any more available?

I've never been rejected because of my certification agency, but I was once initially rejected because of my certification level. Way back in 1992, I took my relatively new Ice Diver cert card with me to Bonaire. When I tried to register as a diver at the resort, the woman behind the desk...

While I do not speak for the HSA, I have to adress some of Diver0001's comments. I was trained as an HSA Instructor several years ago and so my opinions are based on what I was taught in the course and in what I have done since then. First, the HSA does NOT exist as the sole arbiter of how a...

While I too urge you to get training, I have to ask, doesn't your team have a training program? Or do they pay for or offset some of the cost for new member training? How do they determine when you are ready for a callout and who makes that decision?

Kafkaland, I remember when i was just an open water diver (so long ago). Diving in the murky waters of Minnesota, I wasn't too thrilled with the prospect of diving down to 60 feet. then I took my AOW and we did 90ft in an open pit mine north of Brainerd. 60ft didn't seem so bad anymore. But...

About 14 years ago, I began developing a PSD training program for our volunteer dive team. One of the things I found was a compilation of statistics on PSD related deaths and injuries as well as some case studies. As such, this data and these case studies were based on data and events that...

I believe this was mentioned in a recent Training Bulletinn and it was certainly covered in the PADI Update seminar I went to in March. PADI no longer teaches hyperventilation of any sort foprior to breathhold diving/snorkeling.

OK, so for whatever reason, the instructor never attempted to let her try the alternate air source skill again. I really do have to stress that you should try talking to the instructor again. A class B HSA certification means that your wife must have two other divers with her. There is no...

Let us please remember that this is an instructor issue, not a training agency issue. If the Instructor had been using NAUI or SSI materials. He would likely have done the same thing (issued an HSA certification). First, When I went through my HSA Instructor training, it was stressed that we...

Their website does allow you to look for an instructor in your area. And While there is no instructor listed for Santa Cruz, there is one in San Jose. I would suggest contacting him first. As an HSA instructor, I can tell you that even in highly populated areas, there is not a big demand...

We almost always dive tethered. If a diver becomes unconscious, he will let go of the end of a tether, but it won't let go of him (or her) if it is hard attached. This is particularly important in current, where an unconscious diver could be carried off before a safety diver can respond. We...

I think that is similar to what we do here. The Sheriff's office bills the wrecker company and the wrecker bills the owner/insurance co. The sheriff's office used to bill the vehicle owner directly and had very little luck in getting paid. We are also a volunteer team and some of the funds go...

I use a Mk15/G250 and Mk20/S600 in cold water all the time. Of the regulators I've used (Sherwood, Mares, US Divers/Aqualung, Dacor, Poseidon) they are the only ones that have NEVER freeflowed. I'm in Minnesota and my Scubapros have seen plenty of ice dives and Lake Superior.
