When it comes to competitive swimming, the AquaPlus Heart Rate Monitor is a great device to have when you’re trying to keep track of your performance.
FINIS is the company behind the AquaPlus Heart Rate Monitor. This is an underwater cardio tracker that will measure how fast your heart is beating. It uses infrared sensors to monitor the number of beats and it’ll let you know audibly with Bone Conduction Technology. The best part of this is that you just have to attach this light device to your earlobe and you’re good to go. This means you don’t deal with the hassles of earbuds that have the potential of falling off. You can swim as rigorously as you want and do your best without worry about the device slipping off.
