This is a simple compass and tape surveying system. To actually survey land, you will need a Silva Ranger compass. This does more than just tells you which way is north. It is the compass of choice for professional geologists, foresters, prospectors, and guides, as well as surveyors who need a preliminary survey. It has its own built-in protractor and ruler. I sell the Silva Ranger compass for $40. It is also the best compass for use with topographic maps, if you ignore Silva's instructions. I strongly suggest that you survey with an azimuth (360 degrees in a circle) compass. Quadrants may seem easier, but quadrants are an invitation to blunders. A quadrant Silva Ranger is available if you refuse to take my advice. You must be able to read the compass to one degree. A lensatic compass (Army marching compass) or a Boy Scout compass is not sufficient. If you think that you have a usable compass, ask. You will also need a tape measure. I sell a 200 foot Keson indestructable PVC coated fiberglass surveyor's tape measure for $28. If you are surveying small lots or in brushy areas, then a 100 foot tape is better, for $23. For open unobstructed areas, a 300 foot tape is available for $35. Metric tapes are also available, a 50 meter tape is $29 and a 100 meter tape is $46. A 300 foot roll of flagging ribbon is $2. The default color is orange. You might want a circular protractor and tenths ruler to draw pictures by hand, $1 each. A pad of graph paper is $2. Shipping [$5] is by US Postal "Service" for the disk & UPS for the instruments. Turnaround time is about two weeks [my clock speed is 1 microhertz]. Sometimes I'm only « fast and it takes a month.
