Excal II question

L

Lake Hunter

I got to use my new Excal II 800 at the beach this past Saturday. I got to a section of drysand that made the Excal II completely null out. So I put a clad dime down in it and even while being completely nulled out, it still hit on the dime. Is this normal ? I had the disc on 1 and sensitivity a little past the 2 o'clock position and the threshold at a steady hum. Even with the sensitivity totally at it's lowest point it still nulled out in this spot. Could this be that the Excal II is still too hot for some ground or was the blacksand just to concetrated. The spot that the detector nulled out on was about 30' X 30'. In all metal it seemed to work ok but the depth was not great. Has anybody else ever come across this ? I just recieved some Excal books from CJC and am reading all of them. Maybe they will have an answer.
 
Sounds like extreme mineralization. When hunting an area like that keep your swings very short and overlap a lot. Go slow too. It probably would help to hunt in all metal then remove a bit of sand from over the target and recheck in discriminate mode. The Excalibur will null on coins only a few inches deep in black sand.
 
Thanks for the info, it makes me feel better knowing it wasn't all me.
 
Hi Lakehunter,

Any chance of a large deep piece of iron?
I had a similar thing happen and started digging, and way down was the remnants of an old tire with the metal bead exposed outside the rubber carcass in a great big rusty doughnut. May not be what you encountered, but........

Just a thought,

Drew.
 
Yes ... Drew ... I kinda think you have it.
There might be a large metal object or objects down under that sand.
Perhaps a slab of reinforced concrete or a large sheet of iron.

If that is so then any detector you use will not work well, but it seems the Excalibur will find the shallow stuff.
That might be a good thing as other hunters might pass that spot by because their detector nulls out.
It could be your very own honey hole.
