Hi,

I've currently got a Diverite Tranpac harness and was thinking of trying a one piece harness. Can anyone tell me how to rig one?

Plus why aren't there any breaks? Can I not keep one to make it easier to get out of?


TIA
Alan

Hi Alan,

First off let me suggest some useful links to have a look at. First off webbing a harness courtsey of Gas Diving UK

Or you can just buy one ready assembled from a Halcyon dealer or Divingniknaks.

Once you've got the harness assembled you need to position it correctly. This can take a little bit of fiddling to get right and is always covered on the DIR-F course. A good starting article is available by DIR-diver.com

I'd suggest rigging it as suggested and then dive it for at least half a dozen dives. I've often found that you need to give any kit changes a few dives to settle in as the change can be a little odd at first.

It is worth getting someone in the know to help you adjust the harness, I losened mine a bit and from that point on couldn't reach my valves for shut downs. But Clare helped sort it back into it's correct position, having it to loose meant the backplate ends up to low. So now I can reach the valves again

Getting out of the one piece isn't as hard as you might imagine with a bit of practice, just remember to deflate the wing first and if possible drop your bum while the rig is supported, then left arm out bla bla... oh and remove the back up reg first.

Hey Alan,

I've just starting using a single peice harness this year and I think it just takes practice, at the start I think it was ackward to get in and out of but now I've got the hang of it I would't go back..

Just keep playing with it :p

cheers

Hi Alan,

Al has given you a good link to how the harness is rigged.

The reason why there are no breaks is because they break. That is what they are designed to do. DIR is a holistic system so every little thing effects something. The more GUE training I go through the more I find out (often the hard way) about the little details. If you add a break, and it fails during a dive then you will be annoyed by it. If you are doing a long cave dive (10000ft+ into a cave) then it will almost certainly reduce your ability to effectively scooter, particularly carrying multiple stage bottles and scooters. If your ability to scooter is reduced then it will take you longer to get out of the cave. Now think that the cave is small and a syphon (meaning water is sucked into the cave). This reduced ability may well really really slow you down, maybe to the point that you can't make any headway. Now you are likely to run out of gas while still in the cave.

That's why we don't have breaks. They do not give us any real benefits yet can have a noticable effect on efficiency.

Now you may not do any cave diving, and you may never scooter however the system is designed so that anything you do at a base level is the same all the way up to deep long cave/wreck exploration diving.

I also like the following article (not gue, but related)

but as said above, getting someone to go through this with you is worth its weight in gold
