Explorer SE Touch sensitive + unstable

I should mention, the Explorer SE Pro 11 inch coil is far superior to the slimline coil you have. Best coil Minelab has ever designed for the Explorers. I have years of beach hunting on mine and its still going strong. Excellent on small jewelry, deep, stable, slim and light weight for a ML coil. Save up and switch over to that coil you will be much happier.
 
Thanks again for your answer, presuming that the coil is dry, it should not do false signal right ? because it's still doing false signal and hand detecting but it seems to be really dry. Or maybe i really need to put epoxy and then it will stop false signal ?
I am sorry if i disturb you but i am new in this kind of stuff.
Thank you

That's not good news. When the shell peeled away from the poured epoxy it must have taken the shielding paint with it peeling it off the poured epoxy coil. There's no fixing that. Its not enough to simply seal that gap, the coil has to be completely shielded in the shielding paint and the shielding paint itself then also encased in epoxy. Sealing the gap now would still leave an area of the coil unshielded.
 
In theory you would have to cut away the outer shell in the area where its separated, apply shielding paint to the damaged area, hopefully part of the shielding drain wire is exposed. Its not enough to just apply the shielding paint it has to be electrically connected to the rest of the shielding paint and/or drain wire. Then you would have to seal this area back up in epoxy.

The shielding paint is kind of nasty stuff chemically. Also you can't use just any shielding paint you need carbon black shielding paint. There are many other types of spray on shielding paint, nickel based, copper based, but they are actually too electrically conductive the Explorer can detect them. The shielding paint has to be electrically conductive but not too conductive.
 
Looking at your 3rd picture I think its worse than I thought. Its not the outer ABS plastic shell that's peeling away, its the inner plastic shell I think that coil is a lost cause. Here's how the coil is assembled for reference. There is a thin inner plastic shell, the copper coil windings are placed in this shell, then epoxy is poured in encasing the windings. Then this inner coil is completely covered in shielding paint. Then this inner coil assembly is placed into the outer ABS plastic shell, again epoxy is poured in encasing the inner coil completely in epoxy.
 
The coil seems to be really dead then. I will salvage the cable and the plug part. Thank you mate and when i got the other coil i will post here the news. thanks again really
 
Hi guys, i still not have received the coil but before having it i was doing some test and i made a third video of something a bit scary i don't know if it's normal without the coil make noise alone if i touch the plug part or something just when i shake the detector.
I let you see the video it explain better than long message.
anyone know if it's normal or ?

The Explorer is not a tool,it is a finely tuned instrument! The cable would not be yanked and slapped around like that under normal searching conditions,so don't do it now! When I hear of other people having problems with their machines I wonder at times exactly what these machines are being put through. Do NOT yank,slap or otherwise torture the machine unnecessarily...if it doesn't have any real problem right now it will if you keep doing that!
Wait for the coil and go hunt. Be patient!
 
Okay public service announcement, don't shake your Explorer bad idea.

The guts of an Explorer are very well secured except for the ferrite bead. This ferrite bead in the control box, a ferrite tube really about 3/4 inch long, is used to suppress high frequency noise. The 2 battery wires and 3 headphone wires pass through this bead, even bundled together these wires are quite thin and flexible. You are shaking that bead around.

I also don't recommend shaking the coil cable connector. The first 3 inches of TX and RX wire behind the connector are molded in rubber. There is a slot molded into the rubber which the two halves of the control box pinch on but its really just a dust shield it doesn't have a death grip on the rubber portion. Inside the control box you have another 3 inches or so of TX and RX wire that is not molded in rubber, they are just soldered to the circuit boards. By shaking the connector like that its entirely possible to yank on those wires a bit. Also don't be touching the bare TX and RX pins on the connector.

Running an Explorer indoors, as you likely know if you turn on your machine with a coil attached indoors the 50/60 cycle electrical in your house, lights, anything else running off power will be picked up by the detector. The coil and cable are basically an antenna. By disconnecting the coil you have removed 'most' of the antenna that will pick up this electrical interference but not all, you still have about 7 total inches of TX and RX cable from the connector to the circuit boards. Lowering the sensitivity to 1-5 or so should eliminate any interference indoors.
 
Wow ok thank you guys for theses information, i was using garrett ace 250 and tecknetics eurotek pro and in this kind of test they was not doing any noise. Now i understand it's not a toy like my previous detector :) .
I will wait for the coil now and stop playing with it.
In fact im just too much impatient to go detecting that i play around with it like a kid :) the last time i used a detector was 1 year ago and i miss that so much now that i can finally do it again .... Thabks guys for all the help and precious answer i really appreciate .... It's incredible how some people are so kind . Thank you
 
I finally received the coil and the problem is still here.... i can't even take the detector it go crazy instantly even if i dont shake it, im so disapointed i don't know what to do now.... is there anyone who know where it may come from ?
 
Ok so i come back on my last message, the detector is working, i just don't knew it could be that much sensitive to everything.
i goes detecting close to my home for 2 hours, the result is in the picture and i am really happy of my first time with the 15x12 SEF coil, easy pin pointing + GP-Pointer it is just perfect.
I still don't understand something in fresh water sensitivity more than 12 in one place and when i swing the detector it make noise for nothing and 5 meters after with 20 of sensivity it work good just small noise rarely.
Anyway i like this detector, i found a lot of trashes but it is so cool to dig again :) there is one 20Cents euro and 3 old Portugues money (escudos)
And for the weight yes with the 15x12 it's kinda heavy but personally it's not a big problem.
Thank you all for your help the coil was definitively defective.
 
This metal detector is perfectly what i needed, i goes 3 times detecting already you see my first finds in picture the next day i found for 5$ of coin and cleaned the river beach a lot i feel better after cleaning a bit about 1kg of junk.
Yesterday i goes to the beach i found 7$ in coins and cleaned the beach too a lot's of pull tabs and aluminium packing took eveything to the trash i feel like an ecologist :)
This detector work very well in fresh water and even in salt water of ocean i just needed to reduce the sensivity to about 15.
I am happy to have it really it's a good machine
 
Yes you sound like an ecologist with all that "helping nature" you're doing!:lol: After you've run the Explorer for many many hunts and a couple hundred hours you'll only then start to realize exactly how powerful and precise it is. The machine and technology are in your hands. It is speaking to you! All you have to do is learn what it's saying...
You've got a great start,keep it going!
 
Exactly everytime i finish detecting (when im hungry and i can't even walk) i throw all the trash and i feel like im helping the nature and kids that run everywhere without knowing that there can be metal that can wound them. today i found 2 nails so sharp that i could almost don't touch the ending..... i think rust eated the metal and sharpened a lot the nails. Anyways i realize that this detector is very powerful more and more, i jump from dry ground to river and no falsing nothing just.... perfect.
I love this detector so much i want to sleep with him :)

Your detector is a "him"?? :lol: You must like it quite a bit! Good luck Wild...the Explorers are a complete PLEASURE to run.
