Welcome to Radioreference, let's help get you started, first, check the state database for Currituck County, North Carolina & Powhatan County, Virginia to familiarize yourself with the type of communications frequencies & systems available to monitor, then check the WIKI section on scanner types to evaluate the type of scanner you would like & what would best suit your listening needs, also check the North Carolina & Virginia State forums to familiarize yourself with actual members postings which may answer some of your area and/or agency specific needs. Always feel free to ask any questions you may have, and again, welcome to Radioreference.
