WHAT IS A TRACKLOG AND WHY IS IT IMPORTANT?
While following a ‘route’ takes you from one designated waypoint to another, a ‘tracklog’ records and measures the points in between (similar to leaving a trail of breadcrumbs in your wake). Because you are often not moving in a straight line, the GPS unit will continuously measure your travel at specified intervals in order to calculate an accurate distance. Some units will measure at time intervals and other units will measure at distance intervals. Most units will give the user the ability to set the tracklog interval. Keep in mind that the tighter the interval, the more battery power the unit will use and vice versa. If accuracy and not battery power is your primary concern, select the smalllest time or distance interval.
