I like to see a clean transom on boats, meaning that I don't really like cabling running all over the transom.
These would add cabling to the transom as well as a transom mounted X-ducer.
But they are pretty neat and you can adjust the tabs to change how deep the light would go.
That's a freakin bad setup man.........after i get my tabs
That is a Bennett tab that they are bolted to in the pix.
You get a pair of these for $895, which is not that bad considering how much these type lights cost. That's 2 brackets and 4 lights.
This patent pending revolutionary "rock-like" lighting system is
designed to easily attach to the top-side of your trim tabs, and like no other underwater lights these are fully adjustable using your trim controls. Fits Bennett or Instatrim Trim Tabs and is easily adaptable to other leveling systems. In addition to the control of beam direction there is no penetration to the hull below the waterline.
You could make a template and have a shop with a Waterjet cut the stainless mounting plate for you.
