I AM CONSIDERING GETTING A CORTES FOR MOSTLY COINSHOOTING. ANY COMMENTS WOULD BE APPRECIATED. SEEMS LIKE A PRETTY EASY TO USE MACHINE WITH SOME COOL FEATURES. WHAT KIND OF DEPTH IS IT GETTING AND HOW DOES IT DO AROUND POWER LINES OR ELECTRICAL INTERFERENCE? I LIVE IN SOUTHEAST MICHIGAN,GENERALLY SPEAKING WE HAVE LOW MINERALIZATION. THANKYOU.
