Hey BC, The past 2 years on or trips to the core banks(The Greater Island) we have done it and done very well,we were there in Oct&nov, What I done was used a a small coolerwith a inner tube streched around it then aired it up to carry(float)the battery in(stays dry) bought to flounder lights(I like the ones with the globe with the white shield on it(12 volt) but they make some nice LED ones also. made my own SSteal gigs and went to town. My son loved it, he gigged a 7+ lb flounder and nurmous others now he's hooked.We even caught(by hand) and released a very large octopus,amazing animal and very strong. We were on the back side of the Island water usually very clear it is amazing what you see out there at night. gigged all levels of the tide and done well, at hi concentrate on up close to shore around the grass and in the mouth of creeks and coves, sandy bottom is the best,got some on hard bottom(shells) and not much in the real muddy stuff.
About the only other things I can tell you is don't look for the whole fish sometimes al you see is the head(Nose and eyes and a vague outline)once you see one you'll get the hang of spotting them. And if you see the imprint were one was(same shape as a flounder in the sand) slowly look around good most of the time he hasn't went far.Walk slowly & quietly they spook fairly easy. And only gig the ones that look pretty big, because they look bigger than they under water, so when they look like there 20" underwater there only 16-18", we seen plenty so you can pass on the ?? ones.
If you want some pics of lamps and such I can post some.
Good Luck
