Potential Problems Using A Dust Cover In The Summer

Recommended Posts

 I was hunting today with a rain/dust cover on the Nox, in 100-101 degree temps with the sun directly overhead. After 20 minutes my audio starts cutting out and sounding erratic. I notice my screen is looking bizarre, as you can see, every icon was lit up and there was no way to see a VDI at all. My first thought was the cover was acting like a greenhouse and causing the housing to overheat. After about 10-15 minutes of taking it off, things began to look normal once again, within 30 minutes, completely back to normal. I have a Zagg cover on the screen, so, no dust cover for my machine during the summer months.

Thanks for the heads up Dan. Mine has been up into the 90s with no problem but not seen over 100 yet - will soon however.

Operating Temperature Range.... -10°C to +50°C (+14°F to +122°F)
Storage Temperature Range....... -20°C to +50°C (-4°F to +122°F)
Charging Temperature Range..... 0°C to +40°C (+32°F to +104°F)

With cover on and at 100 degrees plus direct sunlight I can see it easily getting over the rated 122F max operating temperature.

After it cooled down, I was unable to adjust the iron bias setting. I did a factory reset and that took care of the issue.

I was out with mine in 90+ for 4 hours the other day with no problems but I certainly keep it in mind.

Great info

I had a similar thing happen a few weeks ago. Posted on a FB Forum:

Hi all. I was out on the beach on the weekend getting to know the Nox and was chatting to a member from an MD forum for a bit. The detector was upright in front of me in the sun. After the guy left I dug a target right where we were standing (a bullet head) when I looked at the screen...it had a large oval-shaped dark spot that took up a large portion of the screen. At first I thought it was due to my sunnies but when I took them off the dark area was still there. I also noticed that all the icons/pixels were showing, even the ones that weren't active. I moved into the shade of a tree and took off the control box cover...the screen was very hot. I thought I'd cooked it but after turning it off for a couple of minutes, letting it cool down in the shade, and restarting it, everything was back to normal...phew! I should have taken a photo but it was very glarey.

I spoke to a ML Technician and he advised that monochromatic LCD screens are subject to being affected like that in high heat situations. Normally, with the movement of general detecting there wouldn't be a problem, but in this case the screen was static and facing directly at the sun for quite some time. No problems since, but I don't leave the screen directly facing the sun while static.

      I hunt in salt water waste deep with both Garrett sea hunter(big coil) and Equinox .was disappointed about the depth i get with the Equinox compared to sea hunter.It does't even touch the depth i get with the sea hunter.It finds of course small stuff which sea hunter doesn't see at all but the depth is lacking.Don't know if i have to sell the Equinox or not,any help?

      Thanks to Chase Goldman for telling me about the Equinox. Looks darn good to me, have read a number of reviews. Will order one today.

      As mentioned previously, after rereading Dick Stout's Coin Hunting... In Depth book over the holidays I took his advice and stepped away from my standard sites to find new ones.  It seems to be working (thanks, Dick).  Statistics on that later in this post.  Last week I went to one of those 'new sites', a century old park, and in the first 2 hours I found 83 cents in modern coins searching along a road and around a crushed stone parking lot that had previously produced only one old coin -- a beat up Wartime nickel ('Warnick').  I decided to move to a picnic area for the last hour, and as you can see in the picture, I was rewarded.  (Sorry for the overexposure on the Warnick.)

      One of the Buffies showed up first, about 5-6 inches.  Next was the Merc at 4-5 inches.  The other two nickels followed (neither more than about 4 inches deep) and the big surprise was the Indian Head, also only about 4 inches deep.  My previous Personal Record ('PR') was only two old coins in one day's hunting.  Note that I don't count Wheat pennies in this category.  My single day PR there is 27.  Needless to say I was quite pleased.
      Oh, the 22 cartridge was found next to the above mentioned parking lot on a previous hunt.  Given that it's in a muni park (and we don't have gang problems..., etc.) I assume this was dropped long ago.  It's possible it was dropped after the park opened by a hunter who was getting his gear together after getting out of the car, before exiting the park on foot into the nearby woods.  The lead bullet appears to have 3 rings, one smooth and two serrated (if that's the correct word).  Can anyone put an age on this?  It was oriented vertically about 6 inches deep and sounded as sweet as any silver dime I've ever found, with the TID centered around 27.  Except for the 'P' on the back of the Warnick, there is no mintmark on any of the other coins.  The IH is 1903 and the Buffie dates are only partially visible.  I think one is 1916 and the other 1924.  None of these is scarce, but they still get counted in my 'other old coin' category.
      A little about the park.  As I mentioned it was established over a century ago.  I knew of its existence but figured so did every coin hunter within 100 miles.  Surely there was nothing left for me....  But another thing I've learned is that there is no such thing as "hunted out".  I've put 52 1/2 hours into hunting this park so far (all in 2020) and there's still more uncovered area awaiting.  Here are some numbers to mull over:  my 'other old coin' finds per hour is 0.27 for this site compared to 0.08 for all other hunted sites since beginning of 2017.  8 of the 14 finds are nickels.  Meanwhile Wheat pennies recovered per hour is 0.21, compared to 0.26/hr for all other sites starting in 2017.  And here is a sampling of my trash finds:

      These are from 12 1/2 hours of hunting this park.  All but a couple of the ring-and-beavertail pulltabs had Equinox TID's in the modern USA coin regions:  12-14 (nickels) and 19 and above.  If the nickel and pseudo-nickel target ID touches 15 I don't dig.  My custom high tone is 20 and up to make sure I notice Indian Head pennies.  (Note from the photo: I count Zincolns as trash and that's what the pictured discs are.)  The 14-18 region is typically thought of as pulltabs, but those in the photo (exception of a couple r&b's) all sounded and TID'ed like nickels.  The aluminum screwcaps TID 21-23.  Crown caps can be in both nickel zone and Zincoln zone (elsewhere, too), depending upon composition.  I did dig more trash than this, mostly can slaw but also some aluminum foil and the usual few bent nails, square nails, copper wire, etc.  This park is absolutely loaded with the old pulltabs, and the broken off beavertails are the worst.  It got to where I was requiring the TID to at least flash a 13 for me to dig 'nickels', and still you see what I pull out.  Unfortunately I later dug a pure 12 and it was a nickel.  😪  I wonder how many of those I left in the ground.
      If you're still here I hope you don't mind one more statistic:  for common coins of denomination 25 cents and less (so not counting Wheaties or other old coins, but including Zincolns), the fraction of nickels among common coins since beginning of 2017 (but not counting this site) is 15%.  At this site (again, not counting the eight old nickels) is 26%.
      In summary, I'm finding a lot of old coins compared to my other sites, but not more Wheaties.  I'm finding a lot more nickels (relative to other coins) than my other sites.  I'm finding tons of pulltabs in the nickel zone.  How does all this tie together?  Simple:  the site has been hunted by detectorists cherry picking the high conductors and ignoring the nickels because they don't want to dig pulltabs.  Of course they missed some Indian Heads (probably didn't want to be bothered with Zincolns either) and a few silver dimes.  Hopefully I'll find a higher denomination silver coin, but even if I don't I'm happy with the oldies that have been showing up.

      After a bit of a drought of finding cool coins with the Equinox, I found another V nickel detecting in the neighbors parking strip in between thunderstorms.  It was pretty worn and pitted, and not of any numismatic value, so I cleaned it up a bit.

      I find myself waiting again for something new they call Apex .
       I had been thinking about buying the Vanquish 540 pro pack but about the time I was going to pull the trigger on it another toy pops up. The trouble is I can’t have it today and not even tomorrow. Just like always I find myself in line waiting on something or someone.
       Well I’m not standing in line for nothing anymore.
       I’ve had a Nox 800 but sold it and I’m still kicking my butt for doing that . I had a detector that out shined all others and like said stupid sold it.
       Enough is enough so I called Rob and ordered a Nox 800 , 6” coil with a extra lower shaft and a MI 6 XP Pinpointer for my ORX .
       I ordered this just this past Monday and by 6 the next morning the check was in the mail. 
      I wish all of you the best that’s waiting on the Apex. Just mark me off that waiting list . Chuck
