Uwatec's batteries last over a decade for the plain depth gauge/ bottom timer. I get wanting to play with the new toy, but admit that is what it is and that it doesn't function very well as the tool it is supposed to be.

Learn your lesson and throw it away. This trinket may be cool but it is pretty useless for real diving. I remember similiar issues with Cochrane 20+ years ago because it was the cool new technology. I finally learned my lesson after wasting tons of money on these types of things.

I prefer overkill for these because I mostly use them when dealing with commercial dive ops on recreational dives when there is an issue - which means they are rarely deployed. One member of the team carries one of the recommended H bags above. I carry one of the carter markers. I think the...

JeffG's quote is right... and wrong. There is a bit of a distinction. There are DIR divers in that those that truly understand the system and embrace the principles know when they are straying, and have hard lines they simply won't cross even for non-DIR dives mostly from a safety standpoint...

Does anything UTD does count as DIR anymore? I don't keep up with the politics of this stuff, but from what I have heard, UTD doing it is pretty strong evidence it isn't DIR at this point. Yes, there are ways to sort of put together a sidemount DIR rig. But, it is compromised from a backmount...

Aside from the obvious of having good basic skills in the water and a good reel, the only trick is the line needs to always have tension on it. The above post covered some ways of accomplishing that but the reeling issues described by the OP sound like a lack of tension on the line when reeling.

Dan will have better explanations about the slightly multi-level nature of the dive profiles, etc. but you are also making incorrect assumptions about the fill pressures of George's tanks.

If the cost delta between GUE training and other agencies is a significant issue for you, don't take up cave diving yet. The most important money you will spend is on quality training. All the other garbage people sink money into early in their diving careers - the latest computer, triple...

That isn't really the point. Three feet is almost always plenty. The issue is, if you have ever actually dealt with someone who just tried to breathe water, not a close call with a low tank, but a true I just sucked water into emply lungs situation. The stress level and situation is going...

I think we are in pretty complete agreement on this one. Swimming for a significant period of time with two stages isn't much fun. Being on a scooter for more than 3 hours also isn't much fun. That is where my general times come in at. One of my first trips diving with Danny maybe a decade...

Open water and wreck are the same thing for purposes of dive time, you can go back with the same amount of ease (assume same type of entry surface vs. boat, etc.). Open water dives are more a matter of maximum decompression obligation in open water. For shallower dives, it is generally more a...

This is why I quit explaining this stuff on the internet. Go load out with 4-5 stages, two on your chest, multiple long body scooters, etc. Now, run the light cord under the long hose and then clip it off. Now juggle the stages around. There is a decent chance the long hose and the light...

Funny how perspectives change over time. I have done cave dives where the turn was beyond three hours. Somewhere around 4-5 hours I always start regretting that. "Fun" dives probably start to end around three hours depending on overal and diving conditioning. For me, open water dives are now...

Routing over and having it slightly tangled after donating air is an easy fix and no big deal. Routing the cord under, clipping off the light and trapping the hose and preventing a donation creates the potential for a problem to become a big problem. The need to donate air is most often...

Well, technically you can see it while on the trigger since you can still see your depth gauge. However, it is kinda useless for checking direction unless it is on your left arm.

Just updating the post in case the info helps someone else out. We went with Jack's Diving Locker. Nice OW operation but without diving with the other ops on the island I can't really say if the price difference is worth it. The advanced dive trips we did weren't really worth it. I did a few...

Can anyone recommend one of the better run dive operations for open water diving in Kona? The recommendations in the Hawaii forum are too generic to provide much guidance on the quality of the operators.

You are correct but they just don't get it. Thal and DA Aqua are the problem in the DIR forum, period. Trace is a great example too. He just wants to argue about it and promote his DIR divers are lemming stance. But since he does it in a nice way, those that don't fully understand DIR don't...

I don't really remember the lead in, so this isn't the actual quote but it was something like, "while your posts have some great information in them, trying to read anything you write is worse than shaving my balls with a cheesegrater."

Isn't that the guy who was the subject of one of GI3 greates lines, the cheesegrater and shaving line?
