Does Anyone Hunt Without A Coil Cover?


Recommended Posts

Is anyone hunting without a coil cover?  If so, how is it holding up?

There has been some talk over on the FT forum about how the Impulse AQ coil is so tough that it doesn't need a coil cover. I wonder if Minelab coils are just as strong.

I've gone through a few coil covers in my day but they are made of soft plastic. The coil itself is hard epoxy. Are covers really necessary? I've always just accepted that they are, but now I'm questioning it.

I bang mine now and then and thankful the cover is there. I look at the cover and see it has plenty of dings and scratches, so it does a good job. ML coils are not completely filled with epoxy, there are structural voids underneath that would collect dirt and would be hard to remove I think, and these some dirt can really upset how detector works. This plastic cover is transparent to the magnetic field, there is probably no gain to be had, besides some small weight off?

Not sure what the return on investment is for NOT using it.  Minuscule weight penalty, no performance penalty, yeah they're a pain to remove and clean, but why risk damage and wear over time to an expensive coil for lack of a cheap piece of plastic?

I wrecked my AT Pro coil by detecting without a coil cover.  Learned that lesson the hard way.  And the AT Pro coil was, IMHO, much more robust than the ML coil.  I always use a coil cover now, especially with the replacement cost of a ML coil.

  I know many people don't like to clean the sand out of the coil cover, and some say that the black sand interfears with the operations! Both valid, if that's an issue for them! To each their own! I just pull the cover when I'm cleaning the rest of the detector and shafts! Which is nearly every time i use it!👍👍

Frankly, anyone that only hunts turf has little need for a scuff cover. Grass will never wear down a coil. Fine sand I'd not worry about much either. Gold prospectors however can wear out a cover in very short order. The machines tend to be heavy, and the coil riding the ground (and the rocks) is the norm. Considering a GPZ 7000 coil is $1500, who would not want to protect that investment? So not only does the ground condition and the hours matter, but the replacement cost of the coil is well worth consideration.

I almost always use a cover, for the simple reason is almost all my detectors get sold eventually. Keeping the coil looking almost new, as opposed to looking like it has been beat to death, will eventually pay off if a detector is sold. I don't drop or throw my detectors, so the coil is the only thing that really shows wear. I can pop that two year old cover off, and have a machine that has only minor scuffs and scrapes when sold.

I have to agree. Using a cover is not a big deal. The advantages of using a cover outweigh any benefits of not using one, at least with Minelab machines. Thanks for all the opinions.

      Does anyone have the dimensions for the control box of the Fisher CZ-3D or the Fisher M-66 Valve and Box Locator? I'm looking for a dust rain cover for the Gold Bug 2 and since they don't make the dust cover anymore for he gb2 I'm looking for an alternate solution other than custom making one. It looks like the CZ-3D or the M-66 could be similar dimensions with the GB2 but don't know. Then again I can't find a dust cover for either of them either, geez!
      The Gold Bug 2 control box is: 5" Deep x 3" High x 4.5" Wide
      Any feedback is greatly appreciated.

      good morning and happy new year to all!!
      I'm sure this question has been asked many times in the past, but I was hoping someone could refresh mu memory. I'm currently swinging a gpx 5000 with a commander 15 x 12 mono coil -- ( old school). I wear out the covers a lot and have had problems getting new ones recently---so question is whats the best way to get the most from my covers??? I 've heard truck beeding stuff works good --- make a new bottom from fiberglass --- or ????
      Thanks all good luck

      Wanted to give the Multi Kruzer a go with the Superfly coil at the beach. Kept the machine in 5khz, manual ground balance as it would drift with tracking on. Was a little bit noisier in spots compared to the stock but on the damn and dry sand it had excellent depth with very stable numbers. Gain was kept around 93 without issue even in the wet.
      One thing I didn't like is if I got any water behind the scuff it would false a bit but outside of that its a good combo.
      Managed to sneak out a Barber dime at 10" in the damp sand in my my 3 hour run, called it a day when I broke my scoop handle.

      I’m surprised I have not seen much chatter on this mod but it seems pretty well done. He has same mod for the Vanquish and maybe the CTX

      Not something I’d do under warranty but maybe after warranty was up?  Or buy a $200 Vanquish or used one and this kit?  
       
      I think the kits are under $300 and I think that includes the headphones?  Heck the waterproof headphones are half that price. Wish I knew Russian...

      How can I prevent my headphone jack from further corrosion?
       
      A little back story. 
      I'm submerging my equinox 800 about 2-3 times per week in saltwater (Florida gulf coast).  
      Purchased the LS PELSO headphones October 11th (1 week shipping) and as you can see they have already started to corrode. 
      I don't take the headphones out and wash the jack EVERYTIME. (Trying to avoid this)
      Please leave a comment, let me know what you do, and what you think will work for me! 
      Thanks

      Well I have now gone through a second GPZ stock coil cover. Has anyone tried out the Nugget Finder coil cover for the 14x13 and if so how have you liked it? I am either looking at one of these or somehow modifying my stock cover to extend the life. If the stock covers were only $10 I could justify the reoccurring cost but at almost $50 ..not really.   Thanks
