TrailLeader 1Find yourself way off the mapLooks like a watch, works like the ultimate survival tool. The new TraiLeader packs everything you need to navigate the wildest of wild places into a compact, rugged stainless steel case. Equipped with rugged ventilated polymer band. A barometer watch and an accelerometer watch for the trail leader.How It WorksThe key to the accuracy of Tech4o watches lies within their accelerometer sensor. The accelerometer sensor works by first detecting changes in the user's movement (acceleration) that are translated into varying degrees of electric current within the sensor. These electric currents are instantly decoded by the Tech4o watches into highly accurate measurements of speed and distance and displayed on the watch face.Accelerometer sensors are commonly found within a diverse range of industrial products in which accuracy is critical to performance, including automobile air bags and tilt meters. Now, thanks to Tech4o engineering, you can experience the same highly accurate measurement of your outdoor performance by using Accelerator and Traileader watches to track your own speed and distance!FeaturesSpeed & Distance Mode:SpeedDistancePace (min/mile)CaloriesStepsExercise/moving timeFully Adjustable Personal Profile10 day memoryDigital Compass Mode:1 increment resolutionAdjustable declinationBearing LockReverse BearingDistortion warningAltimeter Mode:Current AltitudeAltimeter LockReference AltitudeAltitude Alarms48hr Altitude Graph24hr max min altitudeAltitude Difference CalculatorTotal AscentTotal DescentBa
