thanks for the info!
i wanted to use one in my kayak. it is part of the marcum lx9 and needs a way to hold on to it at least, but aiming will be needed too. in a kayak, the winds are calm and so is the water when i take it out.
i was thinking maybe a rod holder with an ice panner might work, but was hoping some one designed one for open water. sounds like marcum should consider it being they designed the lx9 for open water and ice. the camera is designed to point forward in a current. they call it the manta camera and has side and rear fins.
the camera has a ballast, it's weighs 2.5 pounds.
i do use double anchors on trolly's on both sides on the yak when there's a wind.
i have never seen any thing made for this application, but that doesn't mean it doesn't exist.
