Sportline HRM

cnartker

Anyone else use the Sportline HRM ? I have been using it for about a month and seem to like it well enough for the 40.00 it cost. My question is accuracy. It has a chest strap and you do input ht., wt, age....It saysI burn way more calories than my treadmill or MFP fitness . I thought most people found the opposite to be true?
Example: I just ran three miles. My HRM said I burned 501 kcal. MFP said 345. I am a 154 lb. 41 year old female. Any thoughts???
