Hope you like it. I have a really old version of it and still use it, no HRM on mine. I use it in place of an odometer/speedometer and just being able to download the data is great. If I want grade I can get it by importing the data to one of the route mapping web sites. The only way to get good real time grade information IMHO is if the unit not only has a barametric altimeter but also a direct connect (non-GPS) odometer. Short of hanging a plumb line from your bars - grade is hard to measure.
