Tried out the beach mode at an iron trashy land site today....

[Jackpine Savage]

and boy was I pleased with the results! Hit a lot owned by the city about 3 blocks from my house on the main street of our small town. I do not know what used to be there but it is full of nails and other old iron debris. So much iron that if you have -6 and -8 notched out the threshold on the X70 is in an almost constant null. Threw her in beach mode, tracking on and sensitivity from 15 to 21 depending on the amount of iron hits (its quick and easy to make adjustments on the fly with the exterras) Now I have not pulled an old coin out of this site since last fall but not for the lack or trying on my part. Within a half hour I had 3 IH pennies which is the best I have done there since I discovered the spot a couple years ago and they all came in with a definite "dig me" signal in between the iron sounds.

Hi Frank,

That was with the 3 Khz coil. I just came back from regridding the areas I found the IH's using the stock coil this time and found 5 more non ferrous targets. A rimfire Henry cartridge a little bigger than .50 cal. 1small brass spinner blade from a lure, 1 brooch, a piece of can slaw and a really nice 1909 VDB wheat minus the S of course :sad: . I know this was not very scientific but to get this amount of non ferrous good finds for such a short time at this site really amazes me.

I can't wait for the crops to be harvested so I can try this combination at that old country school site. Maybe there is hope to find one or two old coins in there afterall! So if you went back there again, and could only take one coil, which one would it be? HH Randy

Randy,

Kind of early to say on which coil for coins. The stock 7.5 Khz coil hit the smaller stuff better and at pretty decent depths all things considered. I was going slow with lots of overlap using the open center of the coil to "paint" the ground and investigating every non-ferrous response for repeatability. 2 of the IH's read 28/30 and the other bounced at bit more and read in the mid 30's. You really have to work the coil over the target to get any kind of TID stability and sometimes you just go by the tone.
