How old is my Gold Bug 2?

[hoochiemama]

Any way of determining the year my GB 2 was made? Bought it used and am just curious.
Also . . . will a new 6.5" coil work with an older GB 2?

You will most likely have to contact Fisher with the serial number to determine the manufacture date.

If the old GB2 works, what's the diff? TTC
