At Pro Owners May Want One Of These

Recommended Posts


Cool I started to design one that was a bar of acrylic that would fit on the edge of the display but got sidetracked. I was hoping to make it low profile, sticks on with an elastic strap and would be water proof but then I got sidetracked with silly work stuff.

Nice gear. Usually, I don't metal detecting in the dark, but sometimes the screen backlight is very necessary.

Thanks for the link!

That may be very cool solution. Don't stop doing that! It can be very good alternative to the device in first post.

I started to dig through my parts and pieces. I have the plexi but short on an led and battery clip. Have to see what kind of rechargeable batteries around that are small enough that I can use. If possible I'll make it waterproof. Just bee occupied with slew of other projects.

Quickie update, looking through parts I have/can make I started to work this out and rather than use an acrylic bar I thought it would be better to encapsulate the diodes in a frosty white silicone rubber which can act as a pad against the display. This should be much safer on the face of the display and not scratch it. Will have to work out making it water proof later on once I test the silicone and see if it transmits enough light to work. I think if this works out ok, I might be able to make it compatible with the Ace series and maybe other VDI machines that don't have a backlight.

Quick update. Between work and digging I started to prototype the light bar. Printed the part out, put in a couple led's I had and filled it with a platinum cure silicone which the first attempt didn't cure correct as the part was too green (freshly printed) and contaminated the silicone so it didn't cure. I re-did the fill and it seems to be hardening up. Once cured I'll solder up some leads and see if it actually lights up the display. Ends have a couple of t type hooks so i can just rubber band it on the unit. All goes well I'll refine it to something prettier.

Back to the drawing table on this, the led's I chose don't have enough of an angle to light the area and light diminishes too much along the bar only covering about a 1/2". Need to snag some from a light switch but really don't need 16 ft of them either.

Did some poking around and found a nice led back light that only uses 3v and tested well with 2  aaa batteries. With that in mind I made a housing to hold it above the detector and angled so it lights the buttons as well. I am thinking velcro would be fine to hold it in place. Still tweaking and adjusting the parts so they can either be 3d printed or I may make a small rubber mold and bust out a few copies in urethane. It won't be water proof as I originally wanted but not that worried as who wants to dig in the mud in the middle of the night... not like the pull tabs are going any wheres right?

Didn't like the battery box I had so I got around to snagging a small 2xAAA box with swtich and leads already done which of course changed everything else as the dorks put the battery door on the opposite side of the switch. Anyways I printed a part out on my sla printer so the plastic is a bit fragile but gives me a working model. All soldered up it works nice, it's compact and easily detaches since it just velcro's on the top. That little backlight panel works good.

Anyone wants the cad file to fiddle with some more or have some printed on a more applicable printer like fdm or sls just pm me and I'll zip it up. I can also supply the stl.

      Garrett Detectors June 27, 2019 - The AT Max is not just another AT Pro. Tim “Ringmaster” Saylor and George “KG” Wyant discuss the superior performance and key feature differences between an AT Max and Garrett’s popular AT Pro.

      Hi guys, I have a question, can a coil break the detector computer? because a friend has a garrett at gold and he placed the Nel Storm coil for AT GOLD, after using it for a few hours I turned off the detector for lunch, and when turning it on it did not work anymore, the garrett guarantee said it was a factory problem and it replaced. Now, I want to try that coil with different large nuggets 5g, 10g and 15g but I'm afraid to break my detector, is there any way to check the resistance of the coil and values are optimal for AT gold? Could the coil break the detector? I clarify that it is a coil for AT gold

      I swapped out my Nel Big coil on my AT Pro and put the stock coil on and just for kicks I did a quick air test to see if there was any difference and I found that the targets now hit 15-20% further away ie dime at 10 inch instead of 8.
      For those that don't have Garrett machines and a 3rd party coil, the procedure when changing coil Garrett says to do a factory reset of the machine.
      So if anyone knows, does using a large coil setting on a stock coil essentially do a tx boost?
      Do other machines require factory reset after changing coils?

      I have the AT Pro for a while now and it is very reliable. I got it just before the AT Max was released. Buddy just got the Max recently as he was using my Pro and the controls were familiar for him.
      If you don't already have a pinpointer and looking for a complete package then the Max is a great choice. Depth wise it goes about 50% deeper than my AT Pro with the same size coil. That is the equivalent of my AT Pro with a Nel Big coil weighing 3 lbs and measuring 17x15". The true All Metal mode is great in open areas with little or moderate trash, Iron Discrimination on Max is better. AT Pro with stock coil hits quarters 12" or less on average on the ground around here that has high mineralization though I had picked up a Spanish Reale at 14" but it was really faint. Typically in poor conditions the Pro hits in the 10" and under range" which is average for any machine with an 8 1/2 x 11 coil
      Comparing the 2 machines I think the AT Pro audio tones are a little easier to follow and notch discrimination is just a simple 2 clicks.
      The Max has a threshold control that is adequate but I find the lowest tone is none and next tone click up is a little loud. That could be just my preference as I also use a Tesoro with much finer controls since it has potentiometers and is an audio only machine.
      Both the Max and Pro have fairly course id blocks as compared to other machines out there and can limit discrimination but going a block under or over is not a big deal.
      Learning curve on the MAX is really short, no menus to decipher through and you should be up and running in a few minutes. There are no canned pre-sets as many machines have. The AT Pro has canned Standard (noob) mode that bings on a target and is rarely accurate and Pro modes with tone roll that I ended up using quickly and found it more responsive. The Max is basically a more of a professional model of the older Pro.
      I had considered upgrading my Pro to the Max, maybe next year as they are solid and reliable machines and the Max does pretty well in the Salt in the single frequency class.
      If you decide to get one also consider the RnB lithium battery for them. I get over 40 hours running with no performance drop as compared to alkalines that as they wear down the machines performance diminishes. Think the rechargeable battery runs around $80.
