Two questions - need help

[Shambler]

First, an Excalibur II I bought used is acting up after it's been underwater a while, so I believe it's leaking somewhere. It will start making a loud squeal every two minutes or so and eventually it stops detecting metal. The threshold still works but it's like the volume is all the way off. Give it a day and it starts working again. This Excal II has a headset mod so the previous owner could use Grey Ghost headphones. I'm thinking that's where it is leaking. The connection is the same as the battery connection. Does anyone have an idea how I can seal that connection better to help ensure no moisture gets in?

Second, I can already tell I'm going to have a problem wearing out the bottom of the coil. I don't really want the hassle of a coil cover. Any tricks other than marine epoxy to protect the bottom of the coil?

Thank you!

Shambler, I use a pickup bed spray liner called pure rubber coating by blue magic co. for the bottom of my coils. It does real well for me and dries fast if put in the sun. It can be purchased in most auto stores by different names with the same results. GH, Don

Using marine Epoxy with Strengthen the bottom of the coil and the sides of it for that matter.. and When used in Conjunction with the Bed liner spray.. you can't go wrong...

Marine Epoxy is very simple to use.... Its pretty darn easy... Some people Fear the word "Epoxy" just because they are not confident with using it..

one my new frankensplorer SE pro coil, i tried the spray on bedline from rust-oleum.............(Truck Bed Coating)

my buddy uses similar, but from auto store.............made by Dupli-Color

both seem to work great and dry fast like dfxone said.

they both do wear some and i have re-sprayed several times.

just passing along.........fyi

the noise sounds like the battery is getting low from the way u described it...............could be a bad battery............or maybe the charger is not charging it fully or not at all.

headphone adapter plug............is the same as the plug at other end where coil and battery wire extend from.........i have never know one to leak at either end..........i have heard of the knobs leaking around the little oring in them...............many guys hunt in pin point and then shift back to descrim................hundred times a day................

DO U SEE WATER INSIDE THE TUBE....?...........or moisture after it sits.?

DO U SEE WATER INSIDE THE TUBE....?...........or moisture after it sits.?

I seem what appears to be condensation (no real water just rolling around), but when I take the headphones off, the seal is wet. That may be common since it looks like the real seal works on the tiny raised portion of that washer (around the prongs). I'm just not sure. I kind of felt that loud sound every so often might be a low battery - like the Explorer with the low warning. When it stopped detecting metal (could still hear threshold), I put my buddies battery on it and I still could not detect. Since it works after it sits a while, I'm guessing it's leaking. Any ideas for sealing those knobs without losing it for 90 days to Minelab? Their lengthy service has me reconsidering a different brand - that's too bad because their detectors are simply the best.

like u said, something is leaking just a little.

gaskets..............both the battery and headphone gaskets get wet when used in the water...........just part of the deal when submerged.

both ends of the excal tube have big thick o rings that should not leak any, like knobs.........U NEED TO CHECK IT OUT...................

there is a minelab tech named bill branin who has gone out on his own doing repairs..............here is his info...........he has turn around times in days, not weeks or months.
