Radar Tacho RDS II

Sports enthusiasts, especially runners and joggers will find that having a pedometer is crucial to marking their progress in their training schedule, but here’s one for those who want nothing but the best – the Radar Tacho RDS II. This device was developed by Siemensm where it emits microwaves and measures the echos bouncing back from every surface around you to gauge your current, maximum and average speeds – now how about that. In addition, it will also use the same method to keep track of your daily mileage count. Too bad this $205 device isn’t able to perform to the best of its ability when you use it on mirrored or reflecting surfaces, including jogging across a frozen lake.
