Hi eric, quite a few years ago my wife and i came down to your home and bought a goldquest v2 , due to work commitments and many other distractions it has layed dormant for longer than i care to remember, but due to a renewed interest in my once all consuming hobby i would like to know if it would be possible for you to give it a service and if it is possible to convert this machine into a shallow water detector suitable for up to about 5 meteres snorkeling and shallow scuba , thanks mike.
