I went out today for my first low tide beach hunt(very popular beach) with my new PI detector and didn't get many signals. I hunted all the troughs, low points ,ripple sand up and down the beach for 2 hours . most of the things I got were 10 inches + and the detector was running nice on the wet sand. just nothing to dig. what's up with that? jimmy bedrock attached the following image(s):

Lots of pull tabs and other light items like seaweed and shells are another giveaway. If you strike an area where the sand is compact and a dark gray or at least darker then the rest of the beach then that part is eroding away (the dark is caused by heavier metal based sand left behind after the light stuff has been shifted away - think panning for gold). For ripple channels, the seaward side is normally new sand coming in but the land side of the channel is often being scored out by the current moving along the channel. The ripples consist develop from new sand deposited by the current. If there are no targets among the ripples themselves then then 1 - 2m of the slope of the landward side of the channel could be worth a hunt.

I covered a lot of area with my 12inch coil. tried all different parts of the beach zig zaging along, up and down, round and round. I don't think it was sanded in then. was compact in areas and I could see the different colour sands change from light to dark . I must need some more detecting time under my belt.
