palzynski Posted February 3, 2022 Share Posted February 3, 2022 I am not surprised by this coil connector corrosion issue , as these connectors seem to be of very poor quality . Mine is too tight . Last time I could hardly remove it , never seen something like this during 22 years detecting . Even a cheap machine like the Quest X5 ( 170e ) has far much better connectors than the Apex ( 500e ) ... ? Link to comment Share on other sites More sharing options...
phrunt Posted February 3, 2022 Share Posted February 3, 2022 This is very interesting, I'd never noticed that's how the Ace Detector coils are, I checked my Ace models which are the Ace 350 (Euroace) and the newer Ace 300i and the coils they come with plus the extra coils I've purchased for them. My Ace 350 with it's stock coil on the left, the same as the Apex, and the Ace 300i with Nel Tornado coil on the right, note the Nel has the heat shrink over it's connector. A close up of the excellent quality Nel Tornado coil connector, it even screws onto the detector easier than the standard coil and has a little cap you can put on to protect it when not on the detector. A close up of the stock coil, it's a puzzle why they didn't put heatshrink on them, it costs next to nothing, takes a few seconds and the benefits of it for them even in terms of warranty would far outweigh the cost of putting it on. They've used heat shrink under the connector as you can see in this photo, either to make the cable thicker so the connector fits better or for shielding the pins from the outer metal shell of the connector? I should pop one open for a look. Strangely these genuine coil connectors are rougher to screw on than the Nel coil connector. Another of my Ace coils, again the same connector with no heat shrink And all of my Ace coils, the 3 to the left are genuine Garrett coils, the right is the Nel Tornado which by far gets the most use, it's my favourite coil out of what I've got for the Ace detectors, it's a depth demon. Seeing it's raining heavy outside today and I've got nothing to do I'll go through all of my coils and add adhesive lined heat shrink to any coil that doesn't have it on the connectors. Not only will it help prevent rust on my coil connectors it by having the adhesive stops the pulling on the wires/solder joints by adding a lot of strength to the plug end. As they say prevention is better than cure. I do really like my Ace 300i though, great detector for it's place in the market and exceptionally deep in mild soil conditions on coins with a big coil. I think Garrett should "update" their coils by adding the heat shrink on for future Apex and Ace sales, that'd be something I'd want from the next Garrett "update" 2 Link to comment Share on other sites More sharing options...
phrunt Posted February 3, 2022 Share Posted February 3, 2022 And I'm done, that didn't take long ? See the adhesive spilling out of the heat shrink, not only does it make the connector more water resistant it strengthens the connector immensely as the pulling from the cable isn't on the solder joints near as much, with the heatshink going up onto the metal of the plug the pulling of the cable is now transferred to the plug end rather than the connections of the wires. It's about the only update to the coil you could do that would cost about 10 cents but provide a lot of benefits. 1 Link to comment Share on other sites More sharing options...
DIG5050 Posted February 3, 2022 Author Share Posted February 3, 2022 Good idea, Phrunt. The only concern I would have with doing the shrink/melt liner on the Apex coils is the melt liner in the shrink tube makes the overall assembly much stiffer and a bit longer creating more leverage. The mating connector on the Apex is soldered to the main board. Wiggling of the cable with the stiffer coil connector might break loose solder joints on the pcb requiring a (warranty)repair. I change coils a lot on my Apex, and even all the changing of coils as designed is a bit of a concern for me. Just mating the pin/socket connectors is difficult. I’ve been considering applying some silicone grease to the pins/socket portion of the connectors to see if it helps. Anybody ever done this?

phrunt Posted February 3, 2022 Share Posted February 3, 2022 I use this on all of my coil plugs. 1 Link to comment Share on other sites More sharing options...

It'll do the cleaning but not the lube side of it, this one is more the thing which should be in the USA. https://www.3m.com/3M/en_US/p/d/b00034204/ I just spray a little bit on the contacts and also the screw thread, makes it easy to do them up. Some electronics cleaners are harsh on some plastics but the 3M claims it isn't and the brand I use has been fine. This one here seems the absolute best, I might upgrade myself, a lot more expensive though. https://www.synergyelectronics.co.nz/store/caig-deoxit-d5 https://hosatech.com/press-release/why-use-deoxit/ Link to comment Share on other sites More sharing options...
GB_Amateur Posted February 4, 2022 Share Posted February 4, 2022 That 3m product is $50 on Amazon. Can this be done in two steps? 1) clean/degrease, and 2) lubricate? How about this double whammy: https://www.amazon.com/CRC-Contact-Cleaner-Protectant-Aerosol/dp/B007I9Y200/ref=sr_1_4?crid=3OQTP82MXCTZG&keywords=contact+cleaner+and+lubricant&qid=1643940864&sprefix=contact+cleaner+and+lub%2Caps%2C102&sr=8-4 followed by another of your recommended products: https://www.amazon.com/CRC-Heavy-Duty-Silicone-Lubricant/dp/B0042NWOLY/ref=sr_1_2?crid=18XMC2UPJRVZF&keywords=crc+silicone+spray&qid=1643941138&sprefix=CRC+silicone+%2Caps%2C121&sr=8-2 Link to comment Share on other sites More sharing options...
