Nike+ SportWatch

I was wondering if anyone else has this watch. I do use it for running quite often, but I also pair it with my Polar Wearlink heart rate monitor when I am doing circuit training and gym work. I noticed that the calories are way off mark - usually about double what they should be. Does anyone else have this issue? The device is set correctly for my weight/age, but I know that I am not burning as many calories as the watch says, even though my heart range is in the appropriate range to calculate the calories correctly. I have a feeling the watch itself is really only intended for running, so calorie counts for other activities don't add up correctly. This may mean I will have to invest in a more versatile HRM (like the Polar FT7).
