I would like to ask for suggestion on hunting in soft sand. There is a very sandy beach on a nearby lake that gets used heavily in the summer. Sometimes the boats are lined up right next to each other on the beach, which is about 500 yards long. I have hunted it with my Excalibur a couple of times and I get beer caps and pull tabs along with a few coins. I know there has to be lots of goodies there; but they sink fast in the sand. What is the best way to hunt this type of area? I pretty much dig everything that makes a sound and I keep the sensitivity on Auto. I know this type of environment will require more technique and a healthy dose of luck.
