Big coil for sure...set-up depending, but like dirtdoctor said, you WANT to hear it all...what you find will tell you if you are in the right place that has had some traffic and not been hunted in a while...little foil, pulltabs, is what you want to be finding...the high sand gets overlooked by most detectorists...they generally head right for the towel line and onto the wet sand or right into the water...theres good loot to be had on the high sand!
Stop and have a look at the beach, I typically head downwind, (as most people do not like to walk with the wind in their face) and look for a semi-private location on the high sand, off to the side...if its really private and gets some night traffic, you are stone cold golden! If you find a foil condom wrapper, you are in the right area!
You are hunting the travel patterns/habits/vices of people...so even small things like cigarette butts/bottlecaps tell a story of what transpired in a certain location, and who this person was, how long they were there, etc.
You want to hear and find those metal tent stakes, 'cause somebody was there for the whole day! but the BEST locations are where folks have had a little to drink and go down there at night for a skinny-dip...all sorts of stuff gets lost under those circumstances! I found THIS on the high sands...in such a place I described...as well as all sorts of other things of the silver and goldy sort,
I will hunt the water if conditions are favorable, but if they are not, I hunt the high sands! Good Luck, report back as to your adventure please!
