Safety Wearables – Article 5

Continuing from the previous articles on swim safety wearables…

As I have said before, different technology enabled swim safety devices cannot necessarily prevent drowning; they can assist with early detection of a swimmer in distress and draw attention of otherwise distracted parents/guards. The technological advances have evolved over the years, but they still have a long way to go.

One of the recent innovations in drowning detection systems is SEAL System. It essentially creates a virtual wireless network between the SealBands (worn by swimmers), GuardBands (worn by lifeguards and/or parents), and a compact, portable, centralized monitoring Hub. One Hub can monitor dozens of SealBands.

When operational, each swimmer band continuously reports its status to the central hub and to the guard/parent bands using radio signals. The hub registers any interruption in signal and if the interruption is over a certain pre-determined time, it sets the alarm in the Hub, the particular SealBand and the GuardBands. The pre-determined time limit is set for each SealBand. When the SealBand is submerged in water, the radio signal to the hub is interrupted. The alarm is highly audible and visual, and it also makes the bands vibrate.


One of the perceived downside of this system could be – it does not provide the location of the swimmer in distress. However, once the alarm is triggered the band provides a visual ‘glow’ to easily locate the distressed swimmer. But, it may not be easy in the open turbulent waters.

This drowning detection system runs on rechargeable batteries. You don’t have to throw away the system (or it’s components) once it runs out of battery – that’s good!

As an added safety feature, the alarm goes off when the SealBand is unclasped in the water. And just based on how the system works, the alarm also goes off when a SealBand gets out of range (since the hub would not get any signal) – this can serve to alert the parents when a child wanders away.

As always, ensure the system is in operating condition before you let you child wear the band and jump in the water.

Around water bodies, any time you can’t find your child, it’s best to begin your search in the water before anywhere else.
