I played around with my X-Terra 30 yesterday to see if I could gain some more target information. So after being successful, I took it out on a hunt and put it to good use.
It involves using the VCO pinpoint to tell the difference between screw caps and coins. After the target is located, go into pinpoint and centre the coil over the target.When that is done, it's vital that you maintain the same coil height for the next bit.From here, just move the coil around about an inch if a few different direction to see if the target wants to keep increasing the strength of the audio. If you hear it trying to get louder and actually get louder, then you have yourself a screw cap. An Aussie $1 coin because of it's size, can on the odd occasion try to get a smidgen loader, but the difference is only very slight and still distinct from a screw cap. However, I found that coins will maintain the same strength of audio that you get when the max tone is first reached when the target is centred. smaller coins like Wheat's and Indian heads should be easy to tell apart from screw caps, which means that you could go after the shallower ones knowing that you can eliminate a lot of screw caps.
The method seems to be good to about 3 to 4 inches, after which, the signal on screw caps isn't strong enough to cause the audio to increase.Only got fooled twice yesterday by screw caps and they were about 4in deep. One of them had folded sides. As I've only just discovered this method the full extent of it's worth isn't fully known, but it does look to be a very useful method.
I also notched out 16 and included 4 as this made it easy to tell 10c pieces from pull tabs and allowed our 5c pieces to be heard easily as they bounce from 4 to 8.
