Thank you so much for so much helpful information. I really really appreciate it. I am in Northern California and hunting with a Minelab SE Pro. Stock coil but have access to a 10x12 SEF if I need it. You guys requested this info to fine tune the advise. Any more info??? Anyone hunting the Santa Cruz area want a side kick?? I can use my Buddy's tiger shark detector, but wading at chest level sounds like bait to me. I have personally had a few close encounters with the sharks in the area (usually whites). And don't care to have any more. Thanks again guys for any help you can give.
