Flotation has only been brought up a few times throughout this guide but it is a feature that you may want to take very seriously. It is also one that is not mandatory, though. Basically, if a model is equipped with flotation features then it is going to help you gain some additional buoyancy if you accidentally fall through the ice. No one wants to be the one to fall through the ice but having this additional buoyancy can actually end up saving your life (in extreme cases).
