So were do I get a Fred T. back plate?

If looking for a heavy plate there is only one choice. Mine. AFAIK nobody else offers one as thick with as much negative buoyancy as my heavy plate, and nobody else offers a comparable STA.
Hi Fred,
I am producing my regular and large plates in 1/4" 316L now.
Regular weighs 10.4#, Large 12.5#
Bending that heavy plate really makes the ole press groan!

Is one backplate better than another? Do all wings fit all backplates? Do the extra holes along the edge of Fred T and OMS backplates make them superior to Dive Rite or Halcyon? And who makes the best STA?
I want to eventually switch to a backplate and wings setup, and will be primarily diving with a single tank, cold water.

I dive mostly fresh water springs in Fl. 70 degress or so. I dive a TPII now & would like to change over to a BP wing setup. I dive a 3mm Goldcore 1pc, w/a 5mm Shorty/Farmerjohn (sounds silly, but it's a farmerjohn cut off @ the knees & goes on the outside). I dive Catalina 3300 Al80's 34.4# empty, -5.9# Full ; -1.4# w500psi & -0.2# all in sea water. I dove in Orange Grove w/6# & was "maybe" 1# heavy. (eyes just underwater w/full breath) I plan on a dry suit, but not for another year or so.
With all these plates & wings.... My head's starting to spin.....
No wait.... That's the Nitrogen Norcosis.![]()
Thanks man! That weighting was 3000psi & I floated water level @ the top of my frame. I exited w/about 1000psi & was still quite negative. I do Ocean dive when I can, but I like the Cavern/Cave environment. Only thing I find is that in the current set up, I tend to want to be too head heavy & going vertical is an easy thing to do when you stop to do a tie off.SeaJay once bubbled...
Hehehee...
Thumper, I've had exactly the same experience and use similar tanks. Most of my AL tanks are NOT positively bouyant when empty, despite what others' experiences are. Like you, I prefer these kinds of tanks.
Don't forget that getting your weight right involves an EMPTY tank. Looks like you've got the formula down... But is that with a full or empty tank? I've found that it's best for me to weight myself properly at the beginning of my dive, with a full tank, then add four or five pounds to compensate for the air. I'm a little heavy at first, but perfect on deco.
Personally, I've found that a "light" stainless plate is best for me... But I dive both fresh and salt water. If I was diving fresh only, like you are, then I would do either a Halcyon or FredT aluminum plate (the Halcyon is "shallower" than the FredT) or Koplin's interesting SS "light" plate, which is a stainless plate with a good bit cut out to achieve the lightness.
For example, you could do the Koplin "light" plate with his STA, a Pioneer 27 wing, and be perfectly weighted with about 2 or 3 lbs. ditchable weight. I personally like the ACB+ pockets, but a weight belt would do you too.
Over the TPII, you'll find that the backplate/wing setups are much more stable, and the tank "stays put" on your back better. You'll also find that you don't have to wear as much weight (already not too much of a problem obviously) and that the whole rig is even simpler and more streamlined than the TPII.
Good luck!
