How to choose a fitness bracelet for the sea or the pool

Cardiofrequency meter, GPS and training modes are some of the functions to check before buying a wearable for the pool or the sea

Ready for a summer between sea and pool? If we are interested in monitoring our performance while swimming, however, we will need a fitness tracker that records all activities in the water. Choosing the right wearable for the sea and the pool is not easy.

Unlike many people think, not all fitness trackers are waterproof. Many have protections for bumps and drops, as well as sweat and dust. But not all sports activity wearables can be used in water. The important thing is not only the water resistance but also the depth to which the device can go. This is an element that should not be underestimated especially if you like scuba diving or plan to try a freediving course.

ATM depth

As far as depth is concerned, fitness trackers have a rating of 5ATM, which means you can dive up to 50 meters underwater, although some wearables are only rated for 3ATM (30 meters). Before buying a new activity tracker for the sea or the pool, it is essential to understand what we will use it for. Obviously, the greater the depth reached, the greater the cost. If we are going to use the wearable only for snorkeling or swimming on the water then we can buy a cheaper 3ATM device.


During a swim in the open sea the risk is around the corner. That's why using a fitness tracker that records our location via GPS is always advisable. The device, as well as guide us during the activity, could also save our lives in case of illness or sudden changes in sea currents. Without forgetting that in this way, once back home, we can monitor the distances covered.

Heart rate monitor

Most wearables for sea and pool now have heart rate monitors installed by default. If we are interested in monitoring our performance and constantly checking our physical exertion, the heart rate monitor is essential. In addition, the data on heartbeats, will give us a more complete picture of our workouts.

Functions to monitor training

Some fitness trackers already have training modes designed specifically for the sea and the pool. Attention, however, usually these systems increase the cost of the wearable. For this reason, if we are newbies, it is advisable to avoid starting immediately with these devices.

Messages and calls

An excellent waterproof wearable could also have a function for the notification of messages and calls. Beware, however, the devices, such as smartwatches, which consento the automatic response of calls and messages cost enough. Otherwise the solution is to use a smartphone. Which of course must be tied in a waterproof bag. And it remains an uncomfortable solution.
