This is an emergency marker float for diving. In case of an emergency, when you're drifting, or have become separated from the boat, you inflate it with air from your octopus and attach it to your foot to signal your location. Having one of these can dramatically increase your chances of survival. When you lose your guide, get swept away by the current, or suddenly encounter fog – unexpected accidents are bound to happen sooner or later, even multiple times, when you've been diving for a long time. After all, we're dealing with nature. In such situations, this float can seem like a godsend. Carrying this last resort is like having life insurance. The writing on the cover has been erased with a marker. The cover has a used feel to it, but the float itself is very clean. The float has a weight at the base, making it easy to stand upright. You often hear stories of people being saved and thinking, "I'm so glad I had this!" and it's absolutely true. Risk management awareness is a very important skill.
