Could stay horizontal easily, no effort. Then we added a 1 pound ankle weight to strap at top of plate and just a squirt of air to BC and was head down feet up stone cold stable in the water. It was nice to see and feel. Cowling didn't move much at all. We didn't bang or pull on it in water, but was tight before and after the dive. Tanks stayed in place. After giant stride off dock, approx 1 ft from water, no movement or sliding was noted, hooray for innertubes. Wish we had better straps to hold tanks in place and still use cowling.
Lower tank strap wing needs to come up 1 1/2- 2 inches, as the strap comes over the tank right at neck. half on neck and half on cylinder, would like the entire strap to be on the tank. But now we take away a little space of bucket grasping area. I don't think it should affect bucket removal.
Going to extend the but plate area down 2-2 1/2 inches. May also weld a small 1 in angle to the back for cowling rest and attachment point with zuess clip or something similar. But the plate does need to be extended.
And for all PRISM divers out there that really like the stock harness system and BC from SMI, we figured out that we can place 6 holes in the plate and mount the harness and BC from SMI directly to this plate just as the black one mounts to it. James
Hi James, thanks for the update. As for the tank mounts, have you looked into the G-snaps? Also, in place of the innertubes, maybe a pc of non slip contoured material, like what you used on the lower bucket support, would be more effective and appealing with either the stock velcro bands or another system.
Glad to hear that trim was good and I don't think that moving the lower tank tabs higher will be too big a deal. As long as there's a hand width of space to turn the buckett, it will be fine. I usually wind up hitting the bottom of the buckett a few times to loosen the seal, so I would ask that you make sure that whatever you put on the bottom of the plate to help locate the cowling, it should not stick out too far so as not to get in the way of the taps needed to break the bucket seal.
And why do you think the plate needs to be longer/extended?
Very glad to hear that the stock harness will be usable. I myself hope to integrate the upper velcro CL fastening point of the harness and add a waist web belt for the bottom part of the harness which I will loop a crotch strap and the 2 stock fastex CL lower mount pt. loops onto it. Might have to get a new velcro upper CL adapter from Cool Hardware as mine was butchered in the tech harness conversion...
