I've got a Minelab 705 , Gold pack , Fisher F 70 , and a Tesoro Compadre , that may be able to detect gold . Which detector out of these would you use for gold detecting ? What size nugget could be detected with these detectors ? Could one of these detectors detect flower gold in small quantities to alert you to break out the sluice or Gold Cube ? And , in your opinion , What detector would you recommend for gold detecting , if none of the above ? Thanks all .
