Need some help. Tried a search - not what I'm looking for - on this site. Can anyone tell me about GPS receivers. Can you get a longitude/lattitude readout from these units. Having property line dispute with a neighbor and not even his line but another neighbor's. Am concerned about liability when this person and family members tresspass and possible injury. Seems like the type that would utilize the legal system if the occassion arrised. Short of GPS would need the property resurveyed. Any help. Thanks in advance.
