This is a Polar Pacer Pro with a heart rate sensor. I purchased it about two years ago, and have used it on and off. It has a moderate amount of wear and tear. Everything in the photos is included. I forgot to include the charging cable in the first photo, so I've shown it separately. It has been ultrasonically cleaned. A protective film is applied, and I've left it on. You may want to consider removing it and applying a new one. - Brand: Polar - Model Name: Pacer Pro - Included: Box, instruction manual, charging cable - Sensor: Heart rate sensor Thank you for looking.
