I got in a few hours of metal detecting yesteday with my AT Max, which included some time at a park and a few permissions (private homes). Nothing of note was found, although I continued to struggle with trying to find good targets in high-trash soil. Given how I'm using the Garrett AT Max, I know have two primary options for finding good targets (silver coins) in these types of conditions.
First, get a smaller coil, like the 5x8.
Second, start digging the trash targets to clear up the ground and reveal possible good targets that are being masked or otherwise "overshadowed" by all the bits of aluminum, nails and other garbage.
The second approach is not a viable option for most places I hunt (parks and private permissions). Not only do I not have the time to implement that strategy, my body can't readily handle that much digging. Also, I'm pretty sure digging almost everything is bound to lead to the loss of any good graces I have with property owners and park maintenance crews.
Ok, so that leaves the first option. But before I go that route, I have to concede the possibility of getting an Equinox. Based on my experience with my Vanquish, limited time on the Equinox 600 and experiences with my AT Max and Fisher F2, I'm confident that one of the advantages of getting an Equinox will be more stable VDIs and more accurate VDIs at depth. And right now, I think I can live with that.
I understand that getting a solid signal (a good, repeatabe signal from both swings and in 2 directions) on a dime or quarter at 6+ inches in my mineralized soil isn't always realistic with the AT Max. But I know the AT Max is at least capable of getting a decent signal (a good, repeatable signal from at least 1 direction and in 1 swing).
Put another way, I get how the AT Max may not get me the "dig me!" type of signal that an Equinox can, but I at least need it to get me the "take a closer look, please" signal.
All of that to say that I'm thinking about how my AT Max's target separating ability and recovery speed limitations (using the stock coil) will compare to an Equinox 600 and a stock coil. I came to this realization when running the AT Max with only iron discrimination set at 35 resulted in information overload for me and notching out everything below 70 was likely leading me to completely miss "take a closer look, please" signals that might lead to silver coins, dimes or quarters.
Therefore, I want to use Monte's Nail Board. I know it's not ideal, and I plan on using Steve's approach of using both the AT Max and Equinox 600 on real-world targets. But I think the Nail Board will offer quantitative data when comparing the AT Max and Equinox.I also plan on using it with my Fisher F2 and Vanquish 340 to help put things into perspective. So how do I go about doing this test? Here's my approach so far:
Step 1: Create Monte's Nail Board and use it with a modern, clad dime and new nails.
Step 2: For each of the 4 passes, I will give it a rating: Will Dig, Maybe Dig, Won't Dig.
Step 3: I will set the sensitivities at either 50% or the highest possible given EMI
Step 4: I will run each machine with zero discrimination and with enough notching so that it's only going to sound on dimes and quarters (and maybe copper pennies).
Step 5: For the AT Max, I will also test it with iron discrimination set to 35.
Step 6 (maybe): Run the test with the AT Max using both its stock and 5x8 coils.
So here's my first real question: what changes or additions would you all make to my current approach?
My second real question(s): what "base" setting should I use with the Equinox 600. I'm thinking Park 1 with recovery speed set at the highest setting (3?) and a small or moderate amount of iron bias. Should I also run some tests with the Equinox 600 in 4KHz mode?
My third real question: would it be benefitical to modify Monte's Nail Board so that the nails are replaced by either clumps of aluminum or maybe pulltabs? A lot of my hunting is in parks and yards that are often littered with more aluminum trash than iron trash.
Any insight is appreciated. Thanks!
