I bought a White's Coinmaster 5000/D a few months after I posted the above comment. It's in perfect condition and works beautifully. It's so much fun to use that I used it more in the past two months than I used my digital detectors. I knew it was an excellent detector when it first came out about 35 years ago but it has amazed me with some really nice finds. It gobbles up quarters and it totally ignores rusty bottle caps that are a nuisance with my digital machines while still detecting gold and silver jewelry which is what I like to find. I have noticed several other advantages that these old detectors have over the newer ones. Although you have to overlap your swings a lot more with the 5000/D, when you get a good signal, you don't have to dig a hole the size of a dinner plate to retrieve a dime. The target is always going to be directly under the small White's logo on the center of your coil. Since they're not motion detectors, you don't have to keep swinging the coil back and forth over a target.
Here are a few photos of the 5000/D and some finds I've made with it, including a beautiful Texas A&M sterling silver bracelet that I found just outside of a baseball outfield fence.
