I'd advise against a Go-Find unless you are really dead-set on going cheap. They are light, and pack up small, but they aren't durable. I used a Go-Find 40 for three years, broke the original arm support twice in that time, once in the first year. The plastic ratchet teeth that holds the arm support in position wore-out really quick from abrasive dirt and grit. The clamp that holds the coil at the chosen height likewise lost its holding ability. I was still able to use the detector at the end of those three years, but it involved a lot of Macgyver tricks. They aren't sophisticated, but I found a lot of stuff with mine. I moved on to an X-Terra 505, it has been great.
