Im learning that Ground Min. effects every decision in this hobby which detector, which coil, what settings.. etc, My question is this, first I am using an MXT so if I switch to prospect mode this will tell me the number for the ground min. Correct? Does this number represent the range when people say they they have difficult ground, sweet ground, moderate ground.. etc, second question Is there a chart that describes the ground condition for the number range on the mxt? If so then is there also a chart that gives recommendations based on specific ground conditions. Im getting frustrated my progress seems to have come to a halt, As a beginner I graduated from the I dont know what this thing is telling me to doing pretty well finding clad and even some fake jewlery in the 3-4" depth range at fair grounds, playgrounds and parks. But I cant seem to get over the hump to where I am identifying deeper signals at some of the older places I have found to hunt. Any help would be appreciated.

Ground Mineralization

Hello
From what I understand is that, the number you get when in prospecting mode is the VDI number of the ground as in relation to the VDI numbers of your targets. If you want to know how difficult or mild the ground is, in Jeff Fosters book The MXT Edge it tells how to determine that on pages 71 and 72. If you don't have that book it is a fantastic book. Hope this helps

A high GND number does not indicate strong mineralization. It means that the mineralization is predominately ferrous. The GND reading cannot tell you how strong the mineralization is and cannot tell you a smaller coil is in order. As Shwebb said, Jeff has found a way to determine this in his book. I've tried it and it works well. Rob

Hi ,
The VDI number is only used to help identify the properties of a target. I always thought the GND number was mineralisation. I thought of it as a visual reading that runs parralell to your auto ground tracking but if you lock ground tracking the numbers still change according to where you are and help you know if you need to rebalance your ground tracking. My local gold field here in australia ranges from the fifties up to the high eighties on the GND number. Having said that I only use it for one purpose. When I get to a creek or a sandbar I use the GND number to locate the heavier concentration of black sands. The more concentrated the black sands the higher GND number = most likely place the gold was deposited. I mark the highest spot then use the GND number to locate the direction of the paystreak or black sand streak be it under water on under the exposed white sand. Once located stow the detector and hit the pan or just start with my sluice and it's always right on the money.
The smaller the coil the more sensitive it will be and give you a more defined area of where your black sands (ferrous) are.

If you go to youtube and search "flagold". Flagold is the user name. Matt Mattson has 10 finding gold video's. in "Finding Gold V" He explains using the GND number for the above method. He explains it better than I do and shows you too.
