I have discovered that the Bell cyclcomputer sold by Walmart for only $7 makes an excellent electronic counter. Programming is remarkable simple through a single large button, and wheel circumference can be set to 5000 mm for easy operation with one or two magnets. Initially, I noticed what appeared to be a single spurious impulse on some rides, but I was able to track down the source and devise a simple operational procedure to avoid it. It has since performed flawlessly on course measurement.
A full report will appear in the next MN.
