Metal detections

So i just started buying a little bit of silver from reading the silver thread on this forum, it got me thinking about buying a metal detector for something fun to do with my son. Was wondering if anyone is into it and has any advice as far as what kind to buy and what to stay away from, dont wanna go crazy but have a few hundred to spend. Also if anyone has found anything cool i would like to hear some stories...thanks Phone Post 3.0

I use them at work to find the old brass sprinkler heads to backtrack to the valve Phone Post 3.0

I tried the beach but no luck it's not a very good one though Phone Post 3.0
