When I ride with a heart rate monitor the calories I burn are approx. half the amount burned when I don't wear it ??? How is that possible?
SOURCE: Garmin Forerunner 305 miscalculating ascent and calories
Firstly, the ascent and descent are only approximate, and can be very approximate! This is because it's using GPS to calculate your height above sea level when GPS is really only accurate for position Lat and Long. When calculating height, a very, very small error can lead to a large variation in actual height. You should never use a GPS for height if needed for navigation (ie climbing walking etc) If you need accuaracy you will need to get a barometric altimeter.v
As for calories, I think you have identified your problem, it's calculating calories on running not cycling. Not sure what the answer is as I don't know what software you are using but if you are using Garmin TC, bin it and use SportTracks. Takes a bit of getting used to but to really get the best out of your 305 this is excellent software and it's free. Any anomolies like your calorie issue/wrong category import can be changed manually plus a whole host of other stuff. Garmin doesn't even let you edit activities - crazy.

yes the 305 will work with the 500, i use my 305 hrm with both
SOURCE: I want to use my 305 in my spinning class, problem
The heart rate monitor will work. However, the calorie counter will not work since you are not moving any distance for the GPS to pick up.
In most of the new exercise bikes there is a little computer with
a analogic display attached to it which gives you information about how many
calories you've burned, how many miles you've ridden, your heart rate, etc.
