We scan your band when you enter and exit the lake hence the band is a ‘safety tracker’, whilst you are in the water . Most importantly it is your own personal ‘medical ID’ band for any activity you chose. The wristband is not limited to swimming only, anything – running, cycling, walking, supermarket shopping! There is a ‘one-off’ cost for the wristband, but no annual subscription or membership fees – the band is yours and will only need replacing if it is lost or damaged.
