Dear Mr. Late,
Very good advice. I also am just a "Fitness Rider" I like riding but there is no place to ride here with out some SOB running over me. So I just ride in a circle for 30 minutes but I enjoy being out and doing it. The back of the 2 mile circle is in elephant grass and I keep waiting for a Tiger to jump out and have me for lunch.
So my old low tect HRM is fine with a very old Cateye.
