....I always wanted to do this thinking that a gold detector with a high frequency should excel at the salt water beach to find micro gold and other jewelry....in the pursuit of this I acquired a Minelab XT 17000 which has two frequencies....6.4 and 32.5....the 32.5 Frequency should excel at finding the diamond studded earrings and other jewelry....I have encountered a problem with the unit and will need to spend more money to get the problem fixed....I went to the beach last night and was finding small earring stud type jewelry with a Pulse induction unit.....so since the Pulse Induction detector can find this micro type gold jewelry am I just doing overkill with the XT 17000....is it worth the money to fix it ??.......Someone else told me to use the detector for what it was made for ...finding small natural gold nuggets ....using it for beach gold jewelry prospecting is using the detector for a purpose that it was not made for??....hopefully I am not setting myself up for a disappointment.....I would appreciate all comments....Thanks Joe
