Garmin HRM Swim (010-12342-00)

Swimmers' Choice

Already by the name of the HRM Swim, it is clear that it is intended for swimming. So, the heart rate monitor itself is characterized by a high level of water protection (WR50M), and with it comes a non-removable silicone strap. It is not slippery and fits snugly to the body, therefore, unlike analogues, it should not move even during jumps into the water.

The manufacturer also assures that the Garmin HRM Swim is protected from chemicals that are used to purify water in aqua arenas. As a result, the model is perfect for use both in open water and in pools. It will also come in handy for triathlon, but purely for running it is better to consider analogues, like the HRM Run. Its strap will not sweat a lot and rub the skin when jogging, unlike silicone.

Operating principle

The wireless technology used in heart rate monitors today is not capable of transmitting data underwater. To solve the problem, the sensor was equipped with built-in memory. During a swim, all heart rate information and summary statistics for intervals are saved on it, and after the activity is completed, it is transferred to compatible devices.

The Garmin HRM Swim memory is quite large — up to 20 hours, which allows you to do without synchronization for several weeks and not worry about the safety of information about long workouts, for example, marathon swims.

ANT+ technology

The heart rate monitor is powered by a battery, the capacity of which should be enough for 1.5 years when swimming up to 3 hours a week. The model together with the strap weighs a little more than analogues (72 grams), but in water, of course, the difference is not felt.

The sensor uses the ANT + protocol, which means that it cannot be connected directly to most mobile devices. Yes, and compatibility is not available with all Garmin wearable gadgets. Although the most running lines, including Fenix watches and most Forerunner models with a heart rate monitor, “make friends”.

The best choice Garmin HRM Swim will be for swimmers who have a compatible branded watch.
