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?

To Whom It May Concern .
I’ve been around maybe as long as you been making detectors . I purchase my first detector from you White’s back in 1966 . At that time you were selling BFO detectors and discrimination was unknown at that time. That was okay with me being I was young and strong. Oh that detector made me the treasure hunter I wanted to be and before I stepped up to the next White’s detector that one had paid for it’s self . Yes it had paid for it’s self more times than I can remember.
I sorry as we get older we start to ramble.
My last detector I purchase from White’s was the MX Sport. For over a year it got more air time than I’ve ever had. This was from one problem and then another. I have to say White’s was always willing to correct any problem.
The Sport has a weight problem like lots of detectors that’s waterproof in the past . Now that’s all okay in the past but it don’t work today . It’s so many companies offering products that run circles around anything you have on the market .
It’s going to be a sad day when the very best detector is coming from another country. The trouble is that’s the case right now.
I want to say my next detector will be a White’s but I don’t believe that to be true.
I don’t need to tell you what you need to be producing because all you need is look around you. It’s as plain as the nose on your face on what it’s going to take to make White’s great again.
I thank you for hearing me out and I hope my letter will not fall on deaf ears .
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.
