OPENING SEARCH COILS......

Use an LCR meter and measure the resistance, capacitance and inductance of the coil. Jetco coils are not something I have direct experience with so what I am about to say may not be true for Jetco.

Modern day coils are built to be neutrally buoyant in fresh water. That normally means they are filled with epoxy or resin poured in the coil. Trying to dig through that would spell disaster for such a coil. If you really want to see inside, have an X-Ray made and do the measurements I suggested.

The Jetco machine you have, based on what you have presented here, is not something you can turn into a Cadillac. It will remain an entry level machine no matter what you do to it. Just use it as it is to increase your gold, silver and coin count until you have enough to purchase a more versatile machine. Seriously. You cannot make the Jetco any better than it already is.

I had some experience with removing epoxy from circuit boards a while back when fixing satellite equipment, the best was a high heat hair dryer and a fine mechanical dental pick.  You need to go slow and be careful the closer you get to inside components but the heat managed to break it up into fairly large pieces without damaging the circuit boards or parts on it.  It was slow but worked well enough to add in mounts as part of a modification to the boards, no more soldering on the chips.
