Need help deciphering please

Hi. I have a Polar H7 that I just got so I'm trying to figure it out.

I have been using Map My Walk when I go walking. I go around my neighborhood and there's lots of hills. Lots of ups and downs. Distance is spot on with my car when I drive the route to verify it. I mean it's within .03 miles within each other so it's pretty accurate.

I've used the Polar H7 three times now. All of the times I've used the dang thing it says I'm only doing about a quarter of distance that I really am doing. Not a huge biggie I guess cause I know what I'm really walking distance wise


Here's my big problem. They're WAYYYYYYY off in calories. Example one says I burned 500 and the other says 130. It's that big of difference. When I'm doing 4 miles at a time it really adds up in the different amount burned.

I have map my walk synced with my fitness pal. Can't figure the Polar out to sync to anything yet lol.


Thoughts? Feel free to friend me if you want.
