I have been working the local parks averaging 500 coins per month. Last month (March 2016), I found a gold watch and a silver ring in addition to all the coins. I have been using the CTX 3030 with the CTX 17 Smart Coil with excellent results. Most coins found in my area are clad.
I do this for the exercise as I can no long run and do cardio type exercises. I can mosey along with the metal detector for hours though. The exercise and the finds have turned this into my new hobby. It is hard to believe the amount of change we walk over every day.
I was also excited to find my first dollar size Ike coin 2 weeks ago. I missed silver by one year. One last note, I have lost 25 lbs.
