El Dorado 964 Posted December 15, 2012 Share Posted December 15, 2012 If you can't find a factory original, I think I have something that could work........... Quote Link to post Share on other sites
garimpo 2,288 Posted December 15, 2012 Author Share Posted December 15, 2012 Yesterday I emailed the repair center and asked them if they have the parts but I haven't heard from them... Quote Link to post Share on other sites
adam 3,122 Posted December 16, 2012 Share Posted December 16, 2012 (edited) All the dealers should have the OEM handle. Got one off ebay one time, and had to buy another from Rob a year ago. Edited December 16, 2012 by adam Quote Link to post Share on other sites

Mike Furness 1,513 Posted December 16, 2012 Share Posted December 16, 2012 Can't just buy the button anymore ... Have to buy the whole handle assembly ... that is if you buy factory stuff. Quote Link to post Share on other sites
garimpo 2,288 Posted December 16, 2012 Author Share Posted December 16, 2012 Oh Senior Bill S......do you have the button for the OEM or is it necessary to buy the entire unit? Quote Link to post Share on other sites
Hoser John 1,240 Posted December 16, 2012 Share Posted December 16, 2012 Any good ol'american electronicparts house should carry a lousy switch as that as NOT rocket science?? The whole assembly??? NOT GOOD CUSTOMER SERVICE-John Quote Link to post Share on other sites
Rimshot 181 Posted December 16, 2012 Share Posted December 16, 2012 (edited) Is the switch cleanable with spray contact cleaner? Or did your strong Okie hands break it? Edited December 16, 2012 by Rimshot Quote Link to post Share on other sites
garimpo 2,288 Posted December 16, 2012 Author Share Posted December 16, 2012 Rim it's not a switch but instead a button that you push down with your thumb.....unless your like HoserJohn then just push it with one of his five tentacle's (Octopus arms). A spring under the "button" thenpushes it back up.....I had to go back to the ranch house the get my 3500 and a young guy used the 4000for the hour I was gone....in that hour he broke the head phone cord and the bal. button....

GlennM 93 Posted December 19, 2012 Share Posted December 19, 2012 It's a momentary switch in the 6-8mm diameter range. shouldn't be too hard to find if you're able to find an electronics parts place in Brazil Quote Link to post Share on other sites

garimpo 2,288 Posted December 21, 2012 Author Share Posted December 21, 2012 Here's what Minelab repair center has to say.....I asked if the GP3500 handle would work on the GPX's....I believe they do work interchangeably. You shouldn’t have a problem. As for parts to repair. Unfortunately the piece is a moulded handle so getting into it isn’t an option so a new one would have to be purchased.While I was waiting for their answer I went down town to a little shop that sells sewing stuff....they must have a million little andbig buttons.....so we fished around until we found one that would just clear the sides and go down into the recess where theformer ground balance button was.....came home and put the red rubber thing down inside and used a tooth pick to seat it.....now inside that is the white hollow shaft that is connected to the electronics below that make contact for the balance function....Then mixed a very small amount of PC7 and put it in the hole of the red rubber and put the new button on top of that and Ipressed down slightly to get some of the PC7 up through the button holes....Will give it a flight test tomorrow after the PC7 sets up all night....Tomorrow the rest of the story......

garimpo 2,288 Posted December 22, 2012 Author Share Posted December 22, 2012 Glenn after that statement I hate to tell you'll what happened.....Got to the site 29 km from the house.....many hills now with heavy vegation and beautiful gravel that hasbeen detected many times....mostly with VLF's....Anesio took the 3500 and away he went.....I finally got all my garb on and ready.....had to cross a barbed wirefence I parked next too....walk about another 20 feet from the PU.....raised the coil to do an noise cancel.....saw that my newely glued black button was GONE.....along with the red rubber thing-a-ma-jig.....DANG IT....DANG IT.....still had the little white hollow post inside the handle and it does work the balance.....Three hours later started back tracking the 50 feet from where I noticed the button missing....put the Minelabround DD on the ground and slowly back tracked to the PU.....found the little bugger right where I was standingI lifted the detector off the hood....PC7 held the button solid to the red rubber TAMJ.....so now guess it's time for some contact cement on thelittle red TAMJ.....

garimpo 2,288 Posted December 24, 2012 Author Share Posted December 24, 2012 Back at it again today....hate to give up on something so simple....here's what the cavity under the lostbalance button looks like minus the red rubber TAMJand with the redrubber pieceHere's what it looks like in the handle with the rubber hand grip offNow it's started out (easy)it's outWent to the hardware store and got a very small wood screw...cut it to a 1/8"....reinstalled thered rubber thing with contact cement under it.(don't think it will stick to the red rubber)...thenfilled the hole in the white post with PC7 and inserted the screw into thatThen more PC7 and put the shirt button back on top of the screw head with the PC7 comingthrough the holes....tomorrow testIf this doesn't work I'm calling Au and ask who makes the balance plug for them and try to getan email address and maybe buy a couple of the button units.....

garimpo 2,288 Posted December 25, 2012 Author Share Posted December 25, 2012 Repaired part going back in the handleItested it by hand and it seems ok...at least it didn't come apart....Hope to give it the field test tomorrowthe foamrubber on the handle was in bad shape so I nearly tore it up getting the thing off the handle...so for a few more trips I used some of that fantastic green Rescue tape....later I'll go to thebicycle shop and get a handle bar grip.....they work wonders....Spent a little time replenishing the PC7 protection on four of my favorite coils....left to rightCoiltek Joey DD....Coiltek 19" Rd DD.....Coiltek Joey mono and Minelab 11" Rd DD.....since I had time between beers I put Red Rescue tape on the coil cords so their easy tosee and it gives them better stability going into the connector.....

garimpo 2,288 Posted January 11, 2013 Author Share Posted January 11, 2013 Robert you did a great job of finding those switches....thanks a bunch.... The problem with replacing the entire switch assembly is getting the built in cord to work with somethingnew....it would nearly have to be replaced with a original type of switch unless your into building electronics...and believe me I'm not....Still waiting for a response from Minelab on where they source their parts from......I quit holding my breathsince I don't care for the color Blue....I've been using these switches ever since they came out and this is the first problem I've had....I think I mayhave broke the switch when one day I had the detector turned up side down and the switch was resting on thepick-up tail gate....Thanks again for your help....

shep 217 Posted January 14, 2013 Share Posted January 14, 2013 Don't know why they put the switches on top of handle. Put a switch on my 3500??? but in a forward (pistol trigger position), I know, white male republican approach, but I believe it's a better position. How many times when recovering a target do you bump the button? Think about itShep Quote Link to post Share on other sites
