Throw it away if it really has a range of +/- 200 fpm. *It won't be of
any use on any day that's worth getting the glider out of the box.

I found it very helpful last year when I flew my diamond goal
distance.

Wings and wheels has one similar to this for sale on their website.
Obviously it's not my primary vario. I have another vario in the
panel that is +1000 fpm to -1000 fpm. When I rebuilt my panel there
was a sea of rubber tubing that I pulled apart. Now I'm using color
coded tubing for the replacement.

Anyone have a suggestion of how to rig it back up?
