Sigma iD.GO

EKG on arm

The Sigma ID.GO is famous for being one of the easiest ECG heart rate monitors to use. All information is displayed on a rectangular monochrome display in large, readable numbers. The watch itself sits comfortably on the hand, its case is made of durable aluminium, and the rubber strap with a variety of fixation options for almost any brush.

Perfection in simplicity

This device has only 3 functions and one key to control them. ID.GO with the help of a chest sensor measures the pulse very accurately, and thanks to the analogue data transmission format, information about your heart rate can be displayed directly on the cardio machine. Without connecting a chest strap, the heart rate monitor can be used as a regular sports watch and a high-precision stopwatch (accuracy up to 0.1 second). The device runs on a standard CR2032 battery, which can be purchased and replaced almost anywhere. The heart rate monitor also has IPX8 type water protection, which allows it to stay in water for less than 30 minutes at a depth of up to one metre. In this case, being under water, it is important not to press the function key, as moisture may enter the device. It is clear that you can’t swim much with such protection, but it’s very possible to wash off the dirt after a workout.

Affordable and accurate

In operation, Sigma ID.GO behaves more than worthy, the interface is simple to the point of impossibility, and all the information that is displayed on the screen is readable. There is only a remark to the strap — it is quite hard and during intensive, long-term training, the skin sweats a little. Other than that, the Sigma ID.GO is the perfect heart rate monitor for those looking for ease of use and a great price.
