The Wettie Snapper & Kingi floats are tested to 300m. These floats are designed with gamefish in mind. You can rest assured if you nail a big fish and your float gets towed down this float will not collapse like others. These would also make great back up floats for marlin or tuna or buy 3 and stagger them at intervals on a float line to stop your big fish getting away. The Snapper float is the smaller size
