I had purchased this package from Golem Gear on a whim, I liked the price but figured I would never dive it since I don't dive doubles. A friend and instructor offered to set it up for me, the webbing is one piece and I had no clue what to do with it LOL! Saturday he brought it down to the quarry along with his double 100's for me to try with it. We fitted the harness in the quarry office since it wasn't even 30 degrees outside. He decided we wouldn't bother with the crotch strap this time, he said I didn't need it for what we would be doing. Once all my regulators were rigged onto his tanks and we had the harness set where we thought we wanted it we headed outside to the staging area.

I have only ever done one dive in doubles and it was in the 100's I was planning to wear using one of his harnesses, I don't remember if it was a deluxe or one piece though. I was definitely in serious newbie mode for this dive and that's where my observations are coming from.

Getting into the harness was interesting to say the least. My instructor said to crouch down and lift my arms up through the straps. I'm so clumsy I was afraid I would drag the tanks over onto my head though so I put my left arm through the harness, put my hand through the right strap THEN squatted and came up from under the harness to get it on. That worked a lot better for me but the straps didn't want to stay in place, they wanted to slip off my shoulders even when tightened. My instructor thinks I need a chest strap to keep the straps in place; considering the fact I can't even keep bra straps on my shoulders I wouldn't be surprised if he's right.

The next thing I noticed is how short the inflator hose is, that was going to present a challenge in the water so I was a bit concerned.

We all geared up and headed down the icy steps to the water. I didn't notice the weight of the tanks and could easily steady myself and navigate the slippery stairs. The rig was comfortable enough I could have walked for miles without strain with those tanks on. I wasn't wearing a weightbelt and the harness put a lot of the tank weight onto my hips where it was easy to carry. I was a happy camper navigating the stairs and the walk to the water.

Once in the water the problems began. I was expecting some buoyancy issues but the tanks kept shifting forcing me to shift them back with these odd little movements of my back, butt and legs. Reaching the inflator was a chore and since I'm used to a pull dump it was hard to control my buoyancy because I couldn't get it into position or find the buttons very easily. I finally ended up pinning it against my head to work it and was having some success with that. When I was trying to stay neutral above the platform the tanks shifted around now that I had air in the wing; once my left post and tank ended up under my left arm. I was getting frustrated and the odd angles were causing me to get water when I inhaled which was driving my anxiety level up as well. I would get stable then everything would shift and I'd screw up my breathing and drive my anxiety up while fighting with the tanks.

My instructor and I surfaced and he told me I was fighting the tanks, I told him "They STARTED it!" I was almost in tears. He thought I was the problem and didn't believe me when I told him the harness was so loose the tanks could come under my arm...so I demonstrated what they were doing. He had me back up onto the steps and get out of the gear so he could tighten the harness. When he told me to drop my regulator so I could get out I nearly panicked, I was happy as long as I had air but was afraid my struggling to get out of the harness would result in the tanks falling on me pinning me underwater without a reg. I finally dropped the reg so we could get my necklace off then picked it back up while he fixed the harness. He got me back into it and when he tightened it the buckle, which had been centered on my body, was now over my right hip and the tanks still weren't as snug as they needed to be. There had been about 8 inches of slack in the harness allowing the tanks to do their own thing. We went back down and I was a little more stable but the tanks were still shifting and pitching me either forward or sideways. My instructor took my hand and indicated we were going to go for a trip around the plane. I didn't want to leave the platform for fear I couldn't control my buoyancy since I had so much trouble finding the inflator. He steadied me as we limped around the plane and came back to the platform. I was so stressed that I grabbed a small tree when we got back and wrapped my arms and legs around it so I could get my head collected. He tapped me and gave me the "up" but I wasn't mentally in control and I gave him the "time out" to which he returned an "up." I figured if he needed to go up he could go ahead but I was going to stay on the tree until I knew I wouldn't panic if something else went wrong. I closed my eyes and focused on my breathing while he unsuccessfully tried to pry me off of the tree. It took a couple minutes to get my head back in the game and I dumped the wing before letting go of the tree and giving him the "ok, up". Naturally my fin was now tangled in a rope that goes from the tree to the platform so I spent several seconds undoing that mess but staying calm in the process. When we surfaced my buddy said, "What was with the tree hugging? It looked like you were taking a nap." I told him I couldn't surface until I got back in control, if I did I would never dive that rig again. I HAD to have a positive ending to the stressful experience I had endured.

We returned to the picnic table and he adjusted the harness so it was even smaller for the next dive. He told me I needed to get my back arched and get the top of the wing higher than the bottom. The air was going to the bottom of the wing because I always dive head down and it was causing a lot of the shifting problems. I was ready to try it again by the time our SIT was up and the newly tightened harness felt even better on the surface than it had before. We got into the water and this time when I moved the tanks went the same place I did, that felt SO much better. I descended to the platform and was much more stable. I arched my back and focused on keeping my hips lower than my shoulders. It felt really strange but after the dive my buddy said my body position was perfect. I was concentrating so hard on body position that I couldn't frog kick, my right leg was frog kicking but my left leg was doing something really peculiar that probably looked hilarious. I made one lap around the plane without holding onto anyone then on the second lap I went ahead and went through the plane without too much difficulty. The newly snugged harness REALLY made a huge difference. The shoulders still wanted to slip off even though they were tight but I could deal with that. Finding the inflator hose was still a challenge, it's going to take a few dives to decide if I need a longer one I do want to give this one a fair chance. While I wasn't confident in what I was doing I did feel more in control than I had been the first dive. I found myself flailing wildly with my hands and heard my voice telling my students "If you feel like you need to use your hands you need to do something with your BC." so I listened to the voice :D When we returned to the platform my dive buddy clapped to show his approval. I noticed how heavy and hard the tanks were to move through the water on my second lap around the plane, my knees were killing me by the time we got done.

Once we surfaced getting my fins off was another challenge, one came off easily but every time I put my left foot on my right knee to take the left fin off I shifted to the right and did a cartwheel. Four cartwheels later I still didn't have my fin off so I put my leg up on the stair railing and told my buddy to pull it off. He managed to stop laughing long enough to help me :shakehead

All in all it was an interesting and frustrating experience. I would like to try some other sizes of doubles to see what they feel like before I decide to buy tanks.

Ahhh, the fun of doubles.

A few things to think about:

1) Try crossing your shoulder straps, Lynne (TSandM) has tiny shoulders and crossing the straps helps keep the straps in place. PM Lynne, I think she has pictures of how she rigged the harness.

2) Crotch strap will help get things to be more stable.

3) Hog harnesses in general require a bit of tweaking to get right, so keep tweaking things until you get the rig adjusted properly, then think about tank selection. I'd start with 100s, 85s or double 72s, given the fact that you seem to be on the petite side, those would be the three sets of tanks to consider first. AL80s are another option . . . but will require more weight because of their buoyancy characteristics.
 
Try crossing the shoulders straps. TSandM does this with good success. Sounds like things got a lot better once that harness was tightened!
 
Never --ever--set your equipment up for the first time at the dive site--go to a pool and take your time and only do that after you are pretty sure it is ready to go.

Use the crotch strap.

You may need a chest strap or you may want to set the shoulder straps crossed in back rather than straight up.

Your rig was to loose--crotch staps are not really optional. A properly adjusted Hog rig is very stable and solid.

Unfortunately my instructor/equipment provider lives 5 hours away from me so the quarry had to pretend to be a pool. We started the dive on the bottom step of the stairs we used to enter then went to the platform directly below once I was stable there. The pool I train in is 14 feet deep so the only difference was the water temp.

Nemrod:
Use the crotch strap.
That's for the next time, I think he wanted to get the rest of the harness adjusted first since the webbing was new.

I'm glad you described that, I was wondering how to cross the straps in front of my body without choking myself. I was definitely going to need to see a picture before attempting it but now I understand. This is why I don't do well at physics, the pictures my mind draws are not what the problem asks me to draw :shakehead

Actually once we got the harness tightened during the SIT the rig felt stable and solid without the crotch strap. My body position was causing a lot of the problems because my head was lower than my hips sending the air into the bottom of the wing. I had the same stability problem when I went from a regular jacket BC to my back-inflate Ladyhawk.

Oh, Ber, I feel for you! There is almost nothing more awful than a harness that's too loose and double tanks. Having all that mass free to slide around makes the whole dive at best a chore, and at worst almost scary.

I'm sorry, but I absolutely disagree with your instructor. The crotch strap is NOT optional. It's what keeps the rig from shifting upward when you go a little head down, and if the tanks are free to move, then you tilt a little head down and suddenly you're going a LOT head down, because the tanks are headed for the bottom and taking your head and shoulders with them. Plus, as they shift up, the shoulder straps loosen, making the instability worse.

Doubles, with the balancing and weighting issues that come with them, are difficult enough when the harness is properly adjusted and all the pieces are used. Don't blame the rig for the problems you had -- They're fixable.

Crossing the harness straps behind my neck is the only way I can dive a harness comfortably (I have bra strap problems, too :) ).

I haven't dived a set of 100s yet -- I keep bugging my 100-owning buddies, but we just haven't gotten it together. I didn't like the 72s. Nothing I could do could weight me properly AND trim me out in them. But the 85s I bought are almost perfect. I think, especially for us little people, the right choice of tank is crucial for diving doubles comfortably.

Don't give up. Give it another go or two. I've actually found there are ways in which I like diving doubles even more than my singles rig, and if I had as little trouble with the weight of the gear as you're describing, I'd like them even more.

The first time I dove the double 100's in his harness I had a horrible experience that resulted in us breaking the clip that held the crotch strap during an uncontrolled ascent. I was already dealing with some serious anxiety issues just looking at the equipment and that may be why he opted to skip that piece. He's getting the hang of taking baby steps when training me. The shifting gear was frustrating but wasn't as stressful as the unfamiliar inflator and the water I was getting sometimes when I inhaled. It ticked me off when we came up and he wouldn't believe the left post had come clear under my arm, he told me it couldn't and I had a strong word for him before I demonstrated that it could. I know most of the time I'm the problem not the gear but I knew I hadn't started the fights, the gear shifted and I had to fight to re-adjust it. The second dive was so much better once he adjusted the harness so it was tight. When he explained what I needed to do with my body position the tanks didn't bully me as much PLUS I could see in front of me easily. I usually dive so head-down that I have to raise my chest a little to see what's in front of me. I also usually list to the right when I dive; when I was trying to take flying lessons I used to drop my right wing when I flew which drove my instructor crazy. This equipment wasn't forgiving my tendency for poor form. My instructor said I did great once I got my body level and shoulders up, I could actually feel the tanks settle on my back and stay there. Naturally I would lose my concentration and start listing or dropping my head and they would try to shift but I would get my body back in position before the shift got the better of me. Now if I can just learn to keep my body in position and frog kick at the same time I'll be in business.

I'll have him help me adjust the harness so we can cross the straps behind my neck the next time. I have to cross my drysuit suspenders to keep them on too LOL! I definitely had an easier time moving them on land than in the water after a while. My frog kick was all messed up and my knees were really hurting pushing all that weight through the water with a poor kick.

I want to try some other doubles but all my buddy has is 95's and he said they are heavier than the 100's. I was REALLY negative in the 100's so right now I don't want to mess with heavier tanks underwater; he said he has a set of 50's I can try LOL!

It will probably be a while before I get another chance to dive with him. Our schedules don't match very often although now that he's retired it might be a little easier.

I've done dives where I felt like I spent the whole dive darting around trying to stay underneath my tanks, wherever they were going . . .

Crossing the straps requires completely redoing the threading of the harness through the bottom slots (which requires undoing the buckle, hip D-ring, etc) so it's not something you can do quickly.

Switching to doubles makes you feel like a beginner again, like going to a dry suit, or shooting a bag. Ways to stay very, very humble . . .
 
I am a wee bit larger, 5'10" 230 pounds and I wouldn't think of doing doubles with a BP/W without a crotch strap. It stablizes everything as TS&M has said.

In my rig I use soft straps rather than the resin impregnated ones as they allow a quick adjustment once they are on to tighten it up and a quick adjustment once out of the water to easily slip the rig off. My BP has beveled slots that reduce the wear almost to nill so the worries about straps coming apart aren't really a problem. I also inspect the webbing completely before each dive.

Now if I was scaping along inside a cave or wreck with ragged, rough edges and surfaces all around, I would switch to the resin webbing, but most or my dives are open water so the only strap wear and tear is from the BP itself.

Ber,

Everyone is floopy in the water some days(I have the video to prove it) , you will be fine. The crossed straps and crotch strap are a good start. Then it is just practice.

Good luck,

Marc
