Sports Watches for Swimming and Running

What about battery life

GPS is known for its delicacy and its propensity to drain a battery in a few hours. Battery life varies from model to model and only a rigorous test under the same conditions used to evaluate performance in the field. Failing to go running with all models in the arm (which will be too short), know that several solutions available to you. Above all, we will not offend you by reminding you to recharge especially if you plan to run for long hours or if you are planning a hike. Manufacturers have also devised solutions like that Garmin offers UltraTrac. This technology is supposed to save the battery by following a trail instead of a GPS point every second. An intelligent mode is also integrated that switches the accelerometer GPS to save a few precious watts. This is ideal for long trails limiting research satellites. Garmin and a battery life up to 50 hours mode UltraTrac with the Fénix 3 which is intended primarily to the trail.

For the hackers, you can if the urge takes the bike has to bear the recharging base between watch and wrist. Surely this is not what is more comfortable or more elegant, but desperate times call for desperate measures. Connect the charging port to an external battery and voila for ultra-trail or hike along the course. However, keep in mind that this is a very specific case and that most models will accompany you for many hours. If the battery life in GPS mode is your primary purchase criteria, the Garmin Forerunner 920XT is the best of our selection. However if your budget allows you not, you can throw your heart on her little sister, the Foreunner 235 which displays a theoretical life of 15 hours in GPS mode.

How the watches inside or the pool?

If it is fairly simple to understand how outdoor running watch with GPS, how do they do to measure the activity inside or pool? Simply by using other sensors such as the accelerometer which also equips most smartphones. It is he who will be put to use for the race on carpet for example. Need it be said that the watch will be fully waterproof and withstand immersion for use in the pool or at sea as part of a triathlon for example? As such, Garmin recently launched Forerunrer 735XT is waterproof to 50 meters, more than enough for swimming. Moreover, certain watch models have a heart rate monitor as the TomTom Runner 2 or the Garmin Forerunner 235 .

How is measured the heart rate?

So far, the most advanced watches were compatible with accessories such as belts with heart rate monitor to monitor heart activity. This is particularly the case of Polar V800 and M400, or Suunto Ambit3 Run. Now these sensors are integrated directly into the most sophisticated LED watches featured by Centralledwatch. More convenient and comfortable, these sensors use the same technology as the connected watches such as the Apple Watch or the Samsung Gear S2 for example. An LED sends a light signal through the skin to detect the amount of blood flowing through the wrist at a given time. When the heart beats faster, blood flow increases, which results in the acceleration of the rate of absorption of light. To function correctly it is essential to tighten the watch to ensure the contact between the sensor and the skin. If the integration of heart rate is the main buying criterion, orient you to the Garmin Forerunner 235, theSurge Fitbit or TomTom Runner 2 in its version HR.

Integrated Heart Is more reliable than the belt?

It depends on the type of exercise. As part of a split belt is more reactive than the integrated heart rate monitor wrist. Indeed, its electromagnetic sensor does not suffer latency induced by the analysis of blood flow. However, as part of a normal race more or less constant speed, heart rate monitor wrist meets the expectations of riders who may well use it in conjunction with a belt during certain exercises.
