A.T.Pro - A.T.Max coil question

[jack18330]

I have both the A.T.Pro and the A.T.Max with the standard coils. I would like to change to a larger coil for hunting beaches that are heavily hunted on the west coast of Florida. I will be looking for recent drops. Beaches have little to medium trash. Any feedback will be greatly appreciated. Jack

Well, get a coil that fits either the AT MAX or the AT Pro. A Larger coil on the AT Pro will not work on the MAX. The MAX has the true deep, all metal mode. That is the coil I would suggest you go with. Good luck!

I've been using the Detech Ultimate 13 coil that was used on the At Pro and it works just fine on my At Max. I dug 8 CW bullets at least a foot deep, and a very small ball button last time out. I also dug an early milita button on my second hunt about 8" deep between some iron signals. Here's a reply I got from Garrett on the subject... "We do not guarantee any aftermarket products to work with any of our detectors. That said, I do not know of any reason why it would not work.; the At Pro/Max we're designed to use the same Garrett coils, so the connectors are the same." Maureen Wright

I emailed personnel at NEL in December, and they advised me that their MAX coils will not work well on the Pro or Gold because of frequency issues. There were also a few who were disappointed on how much they had to cut back on sensitivity to get them to stabilize them when the NEL Pro coil was put on the MAX.

If they resolved this issue, fantastic!. Then getting an after market coil for added depth is the way to go. I will still suggest that if you order an after market coil for the MAX, get a confirmation from your seller that the coil is designed for and will work specifically on the MAX.

John, I'm a little confused on the coils. The coils for the Pro,Gold and Max are all interchangeable but they have different frequency's. I bought a Nel Hunter coil in Oct for my Max,at that time Nel did not list a Max coil only the Pro.I have been using the Nel Hunter coil here on the beaches of Florida and it seems to be doing ok.Found a buffalo nickel,3 silver coils and 2 silver rings. I usually set the sen. at 4 bars when hunting the trash line on the beach. When I get into the wet sand or water I can increase the sen and it does seems to affect it.A lot of the clad had been on the beach for a long time. Been finding a lot of nickels with the Max compared to the Pro which I used before. I know that their is probably some difference but how much because of the conditions of the ground. Oh, one more thing when I was on the beach the Max started it act up could get it to settle down, notice I had one bar of power. Changed the battery but notice the connector for coil was a couple of turns lose, so tighten it and then it work fine. Don't know which one was the problem. Happy Hunting

The MAX has software built into it to accept the different Garrett coils for the Gold and Pro. The Nel coils have to be built to resonate with the operating frequency of the MAX, which of course is different from the Pro/Gold. The coil connectors are all the dame for the AT models, so switching to a NEL coil on all three is possible, however the overall performance can be different on all three models, depending what the coil was tuned to. So, you read some stories where the coil worked fine, and others say that the sensitivity had to be turned way down. And.......if the coil really performs poorly, is it the AT Machine or the coil? If you send the pair (AT Detector and NEL coil) to Garrett, they won't cover that with their warranty.

I also found that the MAX is really hot on nickels, which also makes it hot on gold rings. I am sure the MAX was tweaked to perform this way.
