It was like nugget hunting at this particular site. The terain was rough and the ground was bad. I used both the stock and the small coil.
Here is my ground readings with the stock coil: FastGrab numbers ranged from 84 to 88. FE3O4 bargraph was either totally pegged at 3 or one bar down at a 1
Using the small coil, FastGrab numbers ranged from 84 to 88 and the FE3O4 bargraph stayed pegged out all the time.
A sens setting of 85 wouldn't penetrate pass the surface and any high conductive targets read in the 90's
A sens setting of 75 wouldn't penetrate pass the surface but the higher conductive target readings stayed closer to true.
Dropped it into the 40's and was able to get a few inches. Overall the machine ran very nice. I used both Disc and All metal. I would like to have a small DD coil for this particalar area. Its full of bottle caps, beer tabs and broken beer bottles, and the small concentric still sees too much ground at places like this.
Got some change, little over $6 and nice little sterling ring. Nothing found here was deeper than 3 inches. It was too trashed to use all metal very long.
Don't normally post pics. but hey, its Christmas.
