I did a quick search and 0 members in this forum with a Minelab go find 20. I would recommend trying to sell the C-Scope 440XD and then buying a Minelab go find 20. I would make a offer of R500 after checking the prices on E-Bay and being non motion. Because i am looking for a cheap detector for my 9-year old daughter. But maybe some other members will offer you more.
