Smart watches are now also able to carry out the job through a similar design to armbands. However, it is difficult for this type to deliver the highest accuracy.
Heart rate monitors are designed with a wide range of shapes and sizes, each comes with different functions and efficient features. In overall, monitors that can be used by placing to the chest through strap are regarded to generate the highest level of accuracy thanks to the proximity to the heart. Other types include optical sensors, which can stack up your heart rate through skin analysis. This type is often worn on the arm so that the result may be less correct than chest monitors. However, if you are a person who feels uncomfortable when there is something strapped around your chest, optical sensors are what you should go with. Smart watches are now also able to carry out the job through a similar design to armbands. However, it is difficult for this type to deliver the highest accuracy.
Currently, a lot of heart rate monitors can do more than just measuring heart rate. Some of them are even able to excel with a lot of fitness metrics such as cadence, vertical oscillation or HRV. Other monitors can also monitor sleep, steps take and the number of calories burnt, according to the users’ preferences, accurately.
Apart from being designed with high quality sensors and electrodes used to measure fitness metrics, a lot of products are also capable of working as pedometers. Some can also measure sleep quality while smart watches are even more functional, enabling users to read and save text messages, play music and even games.
Water proofing and water resistance
There are a lot of things to consider when it comes to this capability. If you are seeking for a device which can work despite a sweat or a quick trip in the rain, water-resistance IP67 or IP68 rating is okay as these devices can be submerged in about a meter of depth for up to a half hour. However, if you want to wear the device when going swimming or you tend to have a sweaty wrist, you should seek for devices with waterproof.
