Is there a 4 inch or small coil option available on the AT Pro? Does it do very well at gold nugget hunting? I may need a waterproof nugget detector for stream crevice hunting when I go to Maine this summer. Might be kinda handy other places too. Can't afford to buy an AT Gold. Also, was wondering if it is possible to use headphones other than Garrets on the AT Pro? And is a plug available to block off the headphone jack when using the speaker, to prevent rain from getting in there?
Thanks.
