......Search patterns are determined by the range of your beacon. The path swept by your beacon should overlap slightly beyond the entire area to be searched to ensure total coverage.
Beacon Range
......When searching for the signal keep a constant orientation and make sure the range of your beacon covers the entire suspected burial area. Set your search parameters so they overlap as you cover the slide area starting at the last seen area. Use 2/3 the radius of your beacon's range to set your search limits to ensure complete coverage.
