Traditional life jackets typically use puffy and stuffy materials which would keep you instantly afloat when you reach the water surface. However, they are not quite user friendly for swimming, let alone diving. Havospark wearable water safety products are designed to be used for you to fully exploit the fun of diving and swimming with minimized hindrance in range of motion either above, on or under the water. They are lightweight, comfortable for wearing and you can hardly feel their existence when enjoying your time on or under the water. During any emergency, simply hit the button or pull the lever and it will bring you to the water surface and keep you afloat.
Common equipment carried by lifeguards are a whistle for attraction the attention of the public, rescue buoy, rescue blankets, and they typically have sufficient first aid items such as AED and hip-packs containing gloves and resuscitation mask(s).
Learn to swim. Also some life-saving skills such as CPR and rescue techniques.
Wear personal flotation devices or life jacket/vest of proper size and comfort.
Drink plenty of water to avoid dehydration under the sun, and dizziness.
Swim in safe areas only. Keep away from strange waters. It is always good to swim in places supervised by a lifeguard.
Don't get too cool. People lose body heat faster in the water than on land, so watch out and get out of water right away when you body start to shiver.
