I used a silver eagle in the early 90's....... Averaged about 6" on a dime.
It was an excellent coin machine, and I found a lot of Silver coins with mine. Of course that was the early 90's so silver was still in about every place one detected. I believe it capable of finding some missed silver too.
I sold it to a friend of mine when I went the Display forward spectrum model and she still uses it till this day.
I had a 6" coil and the 950 coil.. Use the small coil if you can find one for trashy parks. It works very well.You will love everything except the weight..it's beefy but with the supplied arm strap it's workable for long periods of time. 6.5 kHz if I remember correctly.... The display was a ok in it's day..though with some of todays larger displays you may find that a little less than desirable.
Overall it was a fine Whites metal detector and found a lot of nice coins with no problems at all. See if you can locate a 6.5 KHZ 8" coil.. I always thought that would be a great coil on the Silver.
Good luck with your new to you detector........ I wouldn't hesitate to buy one again as it was a fun to use metal detector. Try to find a wide body detector stand...Their out there and it kept the box up off the ground for early morning damp ground hunts..
