The amount of money they want for a reasonably simple mount mechanism is amazing.
At $189, if I really needed a chrono setup that bad I'd just forgo the gymnastics and buy the garmin, lol!
But from the looks of it, with a bit of ingenuity, some bar stock, bolts, nuts, washers and drill bits, I can mimic the important parts and attach it with an existing scope ring mount.
thanks for the help, guys!
