Boring but important

19 Dec

I went hunting yesterday with lawdog1 who is  a member of the Friendly Metal Detecting Forum. He took his AT Pro with the 5×8 coil and I hunted with Maurice, my trusty XP Deus metal detector.

At one point, he asked me to to use my Deus to check a deep, iffy signal he was getting. The signal was an on and off high signal with an intermittent VDI that told him it was a copper penny. His AT Pro was telling him the target was 8 inches deep.

I hit the spot with Maurice and I got a solid but mixed signal. Although I was getting a high tone, my VDI indicated that it was iron wrap-around. Additionally, the horseshoe said “not iron” (If you use the Deus, you know we have a horse shoe graphic that tells us if we are looking at iron or not). My depth said 9 inches (just a pip on the horse shoe). I was using Deus Fast with the 12KHz frequency (I changed it from 18KHz).

We decided to dig the target to see. I dug an 8 inch hole with my Raptor tool and the target was still at the bottom. I pulled the dirt from the bottom of the hole to verify. I dug about one more inch of dirt and out popped out a 1941 wheat in very good condition.

So let’s analyze.

First, I have to say that I am SUPER impressed with the AT Pro. That’s nothing new. I have been singing the praises of the AT Pro for a while now. And I have spoken very highly of the 5×8 coil. Although it was an iffy signal, the Pro with the 5×8 coil, detected a wheat cent at 9 inches. Sure, we don’t have heavily mineralized soil here in Kansas. Well, at least not where we were at. We do have heavily iron infested sites though. By now you should know that mineralization and iron infestation are two very different things.
Be that as it may, the fact remains that lawdog1 got a signal AND a VDI at 9 inches. We both have been doing this for over a year now and we both know how to tell when a target falls from the sides of the holes to the bottom. That wheat WAS 9 inches deep.

Second, I want to talk about two things that are related. Number one is that when you buy a high end detector vs a medium or low end, you will have to interpret more. Data does not become information until you process it. In this case, the Deus gave me data, i.e. the VDI, the tone, the horse-shoe, the depth. I had to then, interpret that data to turn it into information. My information may or may not lead me to dig a target. To be totally honest, I probably would have left that wheat in the ground. The trade-off between more data vs less data is that you may dig less false positives (trash) BUT, having more data to analyze may very well lead you to miss a good target if you don’t analyze the data correctly. This leads to the next thing I want to discuss.

KNOW YOUR DETECTOR! Lawdog1 has been using his Pro now for a while and he knew that his machine was telling him something important about the target under the ground. I, it seems, need to spend more time with my machine and apparently, I need to dig more targets!

So there you have it boys and girls. The lessons never stop in this hobby. And here, I will regale you with wisdom, for free:

IN METAL DETECTING, THERE ARE NO ABSOLUTES. (except that you WILL dig trash 🙂 ).

Thank you for looking!

    You’re much too kind to me.
