But a friend wanted to try MD'ing, he took the E-class, and I took the Prohunter with the older version 8" coil that I had apart to dry it out. That coil came with the PH, and has the Discovery decal, and it only has the black coating on the inside "lower" half. I think Merc said it is for wet grass?
Anyways, it just has been totally unstable and I could not get the ground balance knob to act right, so I thought the mode switch was erratic, or the PH had an internal problem.
Saturday night I finally soldered the broken wires in the newer version 8" without decal, that came with the E-class, and bench tested while apart with targets, and glued it together.
Sunday I went out to a new cellar site with this newer coil on the PH, and thought it was not right because it was so quiet. I kept testing it over my shoes that have aluminum grommets on the lace holes. Then was getting ancient flattened bullets fairly deep, so I knew it WAS working. It works so nice that it seems like a brand new model that I have never used before??? and the GB knob works perfect again.
Trying to recall my first impressions of the PH when I bought it new in the late 1990s, and I am almost positive the PH never ever ran anywhere near this quiet, except on a dry sand ocean beach?
I wonder if this newer coil with the black coating on both the bottom and top of the covers, is just way better?...or maybe the old coil never was completely working right? (the woods are bone dry, no wet leaves)
I will take that older one apart again, but I don't know what to look for, except that fine wire that goes to the coating. That coil was still falsing Saturday when I lifted to hold it out 90 degrees. It took a few seconds to go quiet each time. I did shake test it then, and did flex the strain-relief, and those tests did nothing.
I also glued the 10" back together after bench testing, but have not field tested it yet.
Last month, I did get a indian head penny at a heavily hunted out cellar site that had at least a 100 fresh dig holes on both sides of the road!
