Nugget Shooter 4,617 Posted October 12, 2010 Share Posted October 12, 2010 Just a tip for some of you newer folks, run your wire from the coil straight up the shaft almost to the control box before winding it onto the shaft. The windings will give falsing if wrapped around the shaft just above coil as you swing. We use velcro wire wraps to hold it in place. Quote Link to post Share on other sites
Miner Matt 0 Posted October 16, 2010 Share Posted October 16, 2010 Good point Bill B) I also thinks it helps in protecting your coil cable from getting cut on rocks while working in that kind of terrain. Quote Link to post Share on other sites

garimpo 2,296 Posted October 16, 2010 Share Posted October 16, 2010 A couple of areas that have given me problems on the coil cord isfirst the little screw under the screw down ring...it can vibrateloose and believe me Ace don't have them...a good fix is take yourPhillips jewelers screw drive...ever beeper should have a set...take the screw out and put "thread lock" on the little sucker...end of problems there...I don't know if anybody else thinks of this or does anything aboutit but metals(except gold)forms a layer of oxidation(just anotherform of rust)and may cause false signals or static...my solutionabout every six months is this: go to your local school supplies store and buy a pencil eraserit looks like a lead pencil but inside the entire length is an eraser instead of lead...I whittle the ends for different functionsthen on the one I whittled toa point I take a very small drill bit and make a hole in the eraser so I can clean the male prongs on the detector...slip it on each prong...give it a couple of turns and it's clean...go to the nextuntil they're all clean..Now for the female connectors...I make a small diameter Q tipswab...take a tooth pick andput a very small amount of cotton on the endat this point it helps to add a very small amount of non-abrasivemetal polish to the swab(Wenol or Flitz) works great...then putthe swab into each of the female holes and turn it a few times andyou'll be surprised how much black oxidation you'll get.. then do the same to the other end of the tooth pick for the final clean up...now you have two new tools forfuture use....

garimpo 2,296 Posted December 11, 2010 Share Posted December 11, 2010 Another head scratcher for Dick...after buying some used Minelab detectors I've ended up with a couple of old 11" DDcoils and one of the cords has the outside of the cord coming"unraveled" from age...which leaves two wires inside hanging outin a mess....a guy here makes coils so I took it to him to see if he could replace the cord...he said he could if he hada DD cord...is a mono and a DD cord not interchangeable? Also where can I get a DD cord? Quote Link to post Share on other sites

Birddog 1 0 Posted December 15, 2010 Share Posted December 15, 2010 Hi Bill does these false signals happen with all detectors like pi ones? And would this false signal be at the apex of the swing when you start to swing back?Birddog 1 Quote Link to post Share on other sites
Nugget Shooter 4,617 Posted December 19, 2010 Author Share Posted December 19, 2010 Hi Bill does these false signals happen with all detectors like pi ones? And would this false signal be at the apex of the swing when you start to swing back?Birddog 1This can happen on ANY detector PI or VLF and the falsing is caused by the detector "seeing" the cable coils move with the flex of the shaft and you get a signal, bumping objects will also move the coiled wire giving falsing, when still it is quiet. When the cord is run straight up halfway or better this problem is virtually eliminated. If one must coil the wire down low be sure it is tight at least or there will be issues especially when bumping the coil.The falsing is normally at the end of swing when swinging back and the faster the swing the more the problem will show.Often the coil is blamed by an operator as "noisy" when scrubbing or bumping objects and in many cases I have cured this problem for newer hunters by giving this tip....

I also have a Commander 11" DD and if you touch the connector at the end where the control box is it gives off a whine - it has been slowly getting worse to the point I think I need to change the cord Quote Link to post Share on other sites
garimpo 2,296 Posted December 26, 2010 Share Posted December 26, 2010 Munizaga....I was hoping that Dick would give us his answer to this but so far he hasn't....I'm thinking that the only place possible would be Minelab in AU...I couldbe wrong but I don't think the repair center fixes coils....but about your problem...I believe your having issues with the connector itself...probably a solder joint hasbroken loose....I've had this three times in the last 12 years...and it's not justone coil company either....my fix is to take the coil to one of two TV repair shopshere and they cut about an inch off the cord and then re-solder it back on...problemsolved....

Desertsunburn 44 Posted February 26, 2011 Share Posted February 26, 2011 Electronic tuner cleaner and a old toothbrush, isopropyl alcohol evaporates and leaves a clean surface also-John John, isopropyl alcohol leaves a film. You do not use it on critical electronic components. Also, FYI: If you start polishing connector contacts, you stand the chance of removing the gold plating or cadium plating that is on them. Great thread, Bill...I am correcting my cable now. Thank you. Over time, I really have not noticed but it is coiled down close to the base.Question... Do you really need to coil it at all on the arm??? How about just coiling it in a loop near the top somewhere and tyrap it there??? Is there any effect there???Jim Quote Link to post Share on other sites

frank c 969 Posted February 27, 2011 Share Posted February 27, 2011 Desertsunburn, take your isoprophyl, denatured, rubbing, and any and all alcohol types, get a piece of mirror throughlly clean the mirror.Now apply in a circular motion as if you were removing a stain and then stop lift away the rag, or what ever you use to apply the alcohol with do this with all your alcohol types and then SEE which if any OR ALL leave a film....... SURPRISE !!!!! Quote Link to post Share on other sites
garimpo 2,296 Posted February 27, 2011 Share Posted February 27, 2011 Frank I believe it was you that suggested using Glycerin on the cords to protect them from splitting...by any chance do you know how long it takes to treat 18 friggin cords??? Also one whole bottle of Glycerin!!!!Thanks for letting me know about this product...at least now I have 18 beautiful coil cords!!!! Quote Link to post Share on other sites
Desertsunburn 44 Posted February 28, 2011 Share Posted February 28, 2011 Hi FranKThere were several times in my life where as a tech, we were not allowed to use alcohol to clean components. When I owned GTS (electronic assembly plant) we had a few contracts where we could not use alcohol (Plessey, DEC and Hughes), mainly on edge care connectors. This was at a time period where other cleaning solutions were being outlawed and I actually wanted to try it in our cleaning tanks. Answers came back no. I use to use alcohol on tape drives I worked on. Never had any issues. Then Nortel issued service bulletins stating to not use alcohol on the tape heads. Other manufacturers, we learned, also has similar requirements. I beleive Belden discouraged it's use when cleaning BNC and N-type connectors. Desertsunburn, take your isoprophyl, denatured, rubbing, and any and all alcohol types, get a piece of mirror throughlly clean the mirror.Now apply in a circular motion as if you were removing a stain and then stop lift away the rag, or what ever you use to apply the alcohol with do this with all your alcohol types and then SEE which if any OR ALL leave a film.......
