The Speed Angle APEX GPS Lap timer is an essential accessory for any racer or trackday rider, the data it collects helps riders to analyze their riding style easily, and provide an efficient way to improve the riding skill. You can easily overlay your logs and GPS tracking data onto Google Earth and have your rides replayed 3-dimensionally on the satellite photo images of the track. There is no limit to the tracks that can be overlaid onto (as long as they are available on Google Earth). You can see your riding lines against the track border, and a 3D model bike lean and accelerate just as you did. This feature allows you to compare your rides or compare with your friendsâ€™ rides as if you are in a virtual race or back to back against your own lap data to help find you the quickest way around!
