After running across areas that has too much metal around for a detector to be real effective and finding a few things that even a detector won't sound off on, I decided on building a sifter that was pretty inexpensive, can be carried with one hand, and easy to build.
You will need a cardtable, preferably one that has had one too many Texas Hold-em games played on it. It needs to be one that you can remove the top leaving the frame intact.
You will also need a roll of 1/2" cloth mesh. You can get either metal or plastic. Plastic should work well if you have a water supply to wash the dirt off.
Also needed are some plastic wire ties to hold the screen to the frame. The ones I got are rated for 75 lb. for extra strength.
Another thing that might be helpful are some short lengths of pipe insulation for handles on the sides.
