As a professional instructional designer and a diver who has studied both the PADI materials and those from TDI, I can tell you that PADI's materials are quite poor from an educational standpoint. They seem to pride themselves on how their courses are of such high quality ("you may be able to...

That's definitely the impression that I got. Fortunately, the same instructor had a talk with the shop owner after a bunch of us said we wanted BP/Ws, and shortly thereafter they started carrying a few different setups. Not enough IMHO, but it's a start...

Regarding input from more novice divers about jacket-style BCDs vs. BP/W... I'm relatively new to diving (96 logged dives) and have not done any tech diving as I still do not have enough experience. When I first started out, I dove the jacket-style BCDs because I had to rent and that's all my...

Nice! I'm really looking forward to getting over there - hopefully with a rebreather! ---------- Post added April 22nd, 2014 at 09:57 AM ---------- Have you taken the rebreathers to significant depths (200+ fsw)? Does the WOB became so significant as to noticeably impact the dive, even...

The outfit I usually go with runs a 30-foot, open diesel and usually goes with no more than eight people. Distance to sites are usually only 2 to 3 nautical miles from the harbor, making for trips that are usually about 3 hours long (we go to two different sites). I pay a club rate of $75 to...

My bad. :dunce: I'll be sure to avoid that mistake in the future.

Good point - I should have stated this at the beginning. My long-term goal is to explore and penetrate wrecks and sites of old civilizations (including caves) with the aim of recovering artifacts for study and preservation (by those capable of doing it properly - I have no intention of hoarding...

I wasn't aware that Island Divers was into rebreathers; I thought Ocean Legends was the only shop that serious about them. That's definitely good news.

I've been looking at some rebreathers recently and have been evaluating the pros and cons of the Titan and the Prism 2. I'm interested in getting a few opinions about these two rebreathers from those who are more familiar with the units. The Basics: Price: Both are more or less the same...

+1 on the Dive Rite fins.

I'm attempting to put together a list of Oahu wreck dives: I'm still pretty new to diving, so I'm largely ignorant to what all lies off the shores of this island. Any sites and/or details about the sites would be much appreciated. I'll continue to update the table as new information is provided.

My first computer seemed to have some issues straight out of the box, although I can't say it ever really "failed" because it never stopped doing what it was supposed to do in the water. I exchanged it for a DG03 with an AI transmitter, and am thrilled with the Hollis DC. My buddy also bought...

Yeah, I've received a few comments about that too. The only thing is that I usually only have board shorts around the area that is "streaming." But hey, that's better than streaming yellow, right?

Still no feedback from anyone who has experience using a TX1? I'm very interested in hearing about the performance of this computer. I've come to love my DG03 and might be interested in getting a TX1 now that I'm getting into trimix. Seems like Hollis knows how to make a good DC.

Oh man.... I just spit coffee all over my keyboard! That is f***ing funny!

I have the same camera and had the same problem. What was funny is that the leak happened on a second dive to only 40 feet, after I had brought it down to 110 feet and had no problem. The issue turned about to be some crap on the rubber seal - nothing more. I had opened it between dives to...

I would much prefer the DIN over the yoke, however I'm afraid txtroop is right about a lot of shops not offering a DIN option. I'm one of those guys that carries around a yoke adapter for my DIN reg. It was a bit of a pain at first since it makes the first stage stick out about an inch further...

Could you please clarify what you mean by this? Every issue that I have ever had with an o-ring has been with rental gear. I like to think that I take good care of my gear, but I admit that I'm still pretty new to diving so I could be missing quite a few things.

The two most common mixes of EANx I see are 32% and 36%. I know of a few shops where EANx32, EANx36, and air are the only options. My MOD of EANx32 is 111 and I've never seen any other MOD other than this (given that the plan is to keep PPO2 at a max of 1.4). My MOD of EANx36 is 95 and I...

I have had some similar issues recently with o-rings, both on charters and when renting tanks for shore dives. On two consecutive charters I had one tank which was leaking. One I caught before getting in the water, and the DM said it was "no big deal." I wasn't at all thrilled about this...
