Just wanted to address some of Trace's concerns here as I felt some were a bit misleading.
Perrone, I'm not trying to mislead anyone. I've been involved with the DIR community and GUE for about 5 years. I've seen people complain about things such as the lockdown screw on the primary reel being too small. It's difficult to get a good lock on it and your line will play out behind you unnoticed when it's on the rear D-ring. This is definitely a problem for me because I severed the tendons in my right hand and my grip, when trying to tighten something very small is slightly weaker than my left, even though I'm right-handed -- especially while wearing wetsuit gloves. The dry gloves seem to allow for a better grip. The original GUE answer to that from my instructor was, "Learn to dive." Later, Halcyon began making larger lockdown screws. Of course, before that time, the correct answer to the problem was "doing it wrong." One immediate solution to that problem would be to place it on the front crotch D-ring. Problem solved. Well... not really. See, I was taught that the front crotch D-ring was supposed to be folded under in the "non-scootering position" when you weren't scootering. It's fairly easy to attach a reel to this ring so no big deal, but you can't do that. The reel might drag and it's hanging low on you increasing your profile. Yeah, but... I'm just putting it there for 2 minutes. I'm the primary reel man & I'm just swimming from the basin all of 50 feet before I unclip it to find a primary tie-off? That's not where it goes though. I'm not towing a reel for exploratory diving! If I was, then I could see having it behind me in the slipstream of my tanks & crotch. Yes, but it needs to be a habit. Why? In case you do. Hello! I'm not JJ and I'm going to be spending many years diving in caves that have a main gold line. I only need the reel to run from my primary tie-off to my secondary to the main line. It goes behind you. Yeah, but behind me it gets rough treatment by my buttocks & upper thighs when I kick and may cause the line to spool. That's where it goes. Argh, okay, I'll wear it behind me where it's tough reaching back behind the light canister to get to it & tough to reach back to the left behind the stage bottles - FOR CLASS.
Then, George changed his mind about that and it was moved to the left hip on the internet. I don't know what JJ's policy was or is after that. Of course, the crotch D-ring being out is not DIR according to JJ. Andrew G was incorrect in teaching that. It's a convenient temporary attachment point for bottles and cameras as you switch things around at deco stops or to stow gear during the dive to JJ. Makes sense. Then, I discussed that with my cave instructor who likes it in when not scootering. Less chance of it stirring stuff up when passing through a restriction. That makes sense too. I'm keeping it in. Then, I'm diving and not expecting to scooter. A friend pulls up to me on his and asks, "Want to play with this?" YEAH! My front crotch ring was folded in and I had to undo my harness to get it out to scooter. I tried scootering with it in before and it pulls you kind of uncomfortably.
Then, you watch the GUE Britannic expedition and someone has a white reel on the right side behind the canister light. Is that clipped to a D-ring? To a hole in the back plate? Either way, it wasn't supposed to be there according to the three GUE classes I took. What if the long hose wasn't deployable? & shame on his buddy. Nothing is coming between your long hose and my ability to get MY alloted gas in your tanks.
1. Attach your toolbag to your rear D-Ring. Or your left hip ring if you aren't carryimg bottles. NOTE this is NOT a DIR answer. But from what I have been able to glean, the DIR way is NOT just rigid standardization. It's about a baseline to work from to solve problems.
Placing a tool bag back there will find a diver running into the same buoyancy & trim issues that would come about if butt mounting lights. You would also have too much risk of an entanglement hazard. A monofilament line could easily wreak havoc on your day if managed to snag the bag or tools sticking out of the bag. If you move the bag forward to see what's caught, you can help the line find your canister to your right or your stages to your left. With heavy tools you'd better have that crotch strap sewn because the weight would love to pull your crotch strap free. Sewn is DIR by the way people. As in my above example, the problems are never solved until the generals say they are. Us lowly ogres aren't supposed to solve problems for ourselves. That's why Quest & the list exists.
2. WKPP divers did sidemount.
Then, they weren't doing it right. Sidemounting wasn't DIR. Was this while George was the WKPP project director? He and I exchanged emails about the removal of tanks and the tightness of the harness. He also told me that two of my GUE instructors together couldn't make one good moron and told me a story about having to beat the third. One of my GUE instructors said that if you took George's scooter away he sucks as a diver. So, you've got GUE instructors spending too much time teaching DIR-F and Tech classes, but wow do they look good! And, you've got a world-record holding diver spending too much time using multiple scooters and gases to explore cave systems and not enough time doing Basic 5 and swim skills. Hmmm... why do I think George might know a bit more about diving?
3. I don't think you can fault GUE instructors in the field for what Halcyon products lacked. I've found Halcyon very open to talk about gear and potential changes. Saw it happen first hand last weekend.
I'm not finding fault with them for what EE/Halcyon oproducts lacked. I'm finding fault with them for having defended imperfect products as being that way by telling those of us who knew how to fix them that we were wrong about changes Halcyon eventually made including a larger lockdown screw. I said in my post that the guys at EE/Halcyon were the best dudes I've ever met and really listened to what I had to say -- especially about the pocket being too rigid. You can't get your hand inside especially with gloves. I have sleeker hands than most guys with pianist's fingers and I have trouble getting into the pocket without gloves. I'd hate to be a big guy with catcher's mitts wearing dry gloves.
4. This is also an issue for me, and one I intend to discuss at the GUE conference next month. MANY of the GUE divers are wreck divers. I want to talk to them, and to Jarrod about their training, and why GUE doesn't offer a wreck track. I know that GI was a wreck diver before he headed to the caves, and I know they used to have a wreck class/seminar.
Do that. I'll bet you money they'll tell you that they are working on it. Just like they are working on the open water which is coming out soon. But, no one should learn to dive until that's in play & don't wreck dive either.
5. I don't find this much of a problem. DIR is an evolving thing, and a moving target. BUT, I think a GREAT overemphasis is placed on DIR as gear config. Start with a baseline, modify your team's gear to meet your needs. There was a HUGE DIR thing a few weeks back about diving steel tanks in the ocean.
Steel tanks in the ocean! Say it isn't so! I was taught to dive Dbl AL 80's with no more than 20 min of deco due to changing ocean conditions unlike caves. Then, I found a cave that changed on me in an hour & what about calm seas like in Bonaire? Bob Sherwood started hammering me about a back zip DUI suit when I was teaching a class and told my students in dbls they wouldn't be able to swim twin 104's up from the ocean if their BCD's tore. He was right about my back zip more or less. After 12 years of diving the thing, my zipper finally needed replacing the very next week. At the same time, my students found they could swim doubles up from North Carolina depths in 3mm suits without gas in their wings.
The invention of the Aqualung was the baseline for scuba, then cave divers evolved what was becoming available as time went on until the Hogarthian way became the baseline & then GUE went beyond that. Unfortunately, no other person or group or manufacturer is "doing it right." If JJ phrased Halcyon & DIR as "The Holistic Approach" GUE wouldn't be getting as much press. But, it's almost brilliant to be one of the best groups of divers with some great products and almost say, "We are the only ones who know how to dive." It makes every diver look at your name, your products and diving more carefully scrutinizing everything like never before. That's DIR's biggest gift -- getting people thinking. The backlash is an elitist & competitive diving environment.
You have to use what makes sense. And that's DIR. Think the entire problem through, and plan accordingly.
No, dude, that's called common sense & that's just solid diving.
