Place coil label side up on clean firm surface.
Mark the edge of the two halves in multiple places to assist in re-assembly.
Using a sharp knife, separate the two halves, breaking the glue.
Split the two halves and lay them side by side.
My coil's insides "wobbled" inside the housing, causing falsing at the end of every sweep. This was caused by compression on the white foam insides, crumpling the foam. I solved it by using cardboard shims to lock the coil in place again. You can use smaller but more numerous shims if you'd like to maintain dead center pinpointing, but i elected for simplicity- My pinpoint will now be just a smidgeon to the right of center.
Clean the dust off the black tape, and off the black painted insides of the bottom cover. I used my lungs to blow, but you could also use canned air.
Using the marks made earlier, line up the two halves and press together.
Use Rubbing alochol or acetone to clean the two surfaces that we'll need to reseal.
This also has the effect of removing the marks we made earlier.
I used Amazing Goop Plumbing sealant from Home Depot. I tried to find a sealant that dries hard, clear, and was water proof. Only apply the sealant after the alcohol or acetone has dried completely. You may want to wait an hour to allow for full evaporation- any residual moisture in the coil will wreak havoc on the electronics.
Using the applicator, lay a bead around the edge and allow to dry per manufacturer's specifications. I used a popsicle stick to clean up the bead some.
That's how I repaired my Blue Max 600 coil. This repair may also work for the Black Max 600 and the Bull's Eye 5.3.

I use a back hoe to carry it around.
