one thing that i've found to be very helpful to me is to go by word of mouth. a lot of people research just one or two small areas and set all their hopes in getting permission to hunt those areas. when permission is denied, some of them seem to fall to pieces. living in central virginia, there's still large tracts of land available to hunt. it doesn't matter one bit to me if it's been detected before - no one man or machine gets it all anyway. i've rarely lacked for a place to go in my nearly thirty years of detecting. i know there's a lot more no trespassing signs going up. that doesn't deter me in the least. most are up for a good reason. there's still plenty of land out there to hunt - so let me offer you some tips.
everyone [and i mean everyone!] that i know or meet within the first two minutes of our conversation will know for certain that i like to detect and would be interested in any land they might have or would know about. i've gotten so many good spots like that. people i know at work, the cashier ringing up my purchases, people in line with me, cops, family members, etc. are all given the "gg spiel". i'm quick to add that i'll probably never get rich detecting [true] and enjoy doing it to uncover and preserve history, and that i don't leave open holes. try saying all that in one breath! it works well for me. i always have a pen and small notebook handy and follow up on as many leads as i can. it stays in the dash of the car too.
as long as you come across as interested, respectful and genuine, you shouldn't have much problem getting permission. people talk, don't forget, so i know if i do a lousy job of covering my holes, letting the cows out, or some other dumb mistake, my chances of going back to that new spot are slim to none. doing a good job on one piece of land can often lead to other places to go. word of mouth is the most powerful tool in my arsenal, and it has to be cultivated and groomed. sure, i get rejected once in a while, but that doesn't deter me in the least either. there's plenty of other places to go to.
those who don't cover their holes, let the man's cows out, conceal their finds from the owner, and generally disrespect the landowner - and consequently, the hobby itself - are in for a long, bumpy ride. like i said, word gets around, and people talk. word of mouth is the way to go, my friend. we often don't know if the place has been detected before or not, so instead of targeting an area or two, and pinning all my hopes on those, i get permission for as many acres as possible. it works out better that way. good luck, fellas, i hope this helps you. hh,
