What is the cone on JVD's front deck?

We've gotten several questions today about the orange cone sitting on Jonathon VanDam's front deck. See the photo.This is not a traffic cone, it's a Flogger Underwater Viewer, made by LureCraft. Place it in the water and, by blocking out the sun's reflection, the Flogger gives anglers a clear view of what's under the surface. It is typically used in clear, shallow water, and is particularly useful durning spawn. Mark Zona talked about it on Bassmaster LIVE today. And JVD told Steve Wright he caught a spawner using it today.
