The RAC Geo II has an on board GPS receiver built into the unit Once it locks onto the GPS satellites it can track movement Power is provided by a cigarette lighter adapter which makes the unit completely portable from vehicle to vehicle Power can also come from any existing DMI power wiring if you already have this While the on board GPS receiver will track distance we recommend the use of the external GPS antenna for the best accuracy This screws into the top of the Geo II and comes with the unit Accuracy using GPS based distance measuring is approximately 1 foot per 1000 feet If you require greater accuracy an external distance sen sor such as a modular or magnetic sensor can be used with the unit to provide accuracy up to 1 foot per mile 5280 feet In addition to distance measuring the RAC Geo II also has the unique ability to track and store GPS coordinates using the on board GPS re ceiver The GPS coordinates of road features intersections bridges signs guardrails etc can then either be internally stored for download to the RACPro software or read directly off the RAC s display 14 Chapter 2 Installation Chapter 2 Installation RAC Geo II User s Manual Before You Begin The JAMAR RAC Geo II distance measuring instruments are very reliable However there can be some external variables that could affect proper op eration and the ability to accurately measure distance traveled By observing a
