Concrete

[Brignack Killer]

I was at a house next door to mine detecting. I was finding a few coins there and a couple wheat pennys too. I went to search over a walk way that had 2'x2' concrete steps they are 2 1/2" thick. I got a hit on the 3rd one it showed a dime and a penny 8" down. I didn't think the F4 could pick anything under concrete so I pasted it up I was over the the next step and didn't receive any signal at all.

So I thought I better go check out the other step out again. I removed the step and rescanned the area and the F4 still showed the dime & penny 6" down. Sure enough I dig down 6" and I pull out a dime and a penny!

I'm very new at all this. So is that normal for a metal detector to be able to read anything under concrete?

I think concrete is no problem to detect through as long as it doesn't have rebar or other metal reinforcement in it.

Most detectorsa will detect through just about anything that's not metal. I have dug old coins through asphalt before. Needless to say - very hard digging, Steve in so az

BG - I was digging silver and lots of wheats right up to the asphalt so I dug as much as my hands could take. Got a few more wheats, steve

Thanks for the info guys. I just though it was cool that the F4 was able to see the dime & penny 6" below the concrete step.
