I've had some good results hunting high tide. One day on a steep section of beach each wave was depositing. I could actually see coins come up the slope on occasion. The coins would then slide back about two feet and stop. All I had to do was wait for the wave to recede and then run out and detect until the next wave came in. That was quite exciting. As an added bonus, there was no competition as most dectorists wait until low tide or there abouts.
