Sportline DUO 1025 Heart Rate Monitor$69.95
3 stars based on 3 reviews 
I would recommend to a friend
Works Great 5 I have had Sportline Duo for almost 3 years. I got it after open heart. I like the option of chest strap while exercising and touch any time I want get my heart rate. I have replaced the batteries a couple of times. I use the starp about 5 hours a week and have had to replace the battery only a couple of times.

like mine so far 5 mine works great but i have only had it a little while. sounds like the guy above needs to change his battery. i think the battery life is short on these because they do a lot of processing and that takes power. need to read the manual because you won't figure it out on your own. the chest strap/monitor is spot on

Sportsline Duo 1 worked for about 3 months. Now it changes from 12 hr mode to 24 hr mode and clears the month and date. This is the second sportsline monitor i purchased. I need a good heart rate monitor as i have an internal DEFIBULATOR and want to know what my rate is when im active....NEVER AGAIN will i purchase this brand.......
