I have two Dub-L-Seat Livescope/Active Target/Humminbird Mega 360 mounts that are specifically for use with the Minn Kota Ulterra for sale. Due to some confusion when filling my order, I have three of these mounts. I only need one.
I use this mount to deploy my Livescope as the Ulterra deploys. This mount eliminates the need for a separate deck mounted unit that would require me to drill more holes in my boat and have more loose wires around the decking. I use the mount with The Livescanner that allows me to mechanically turn the Livescope without turning my trolling motor. The mount is so well balanced that the trolling motor doesn't even know it is there. I have been using mine for several months and I love it.
If you have the Ulterra and use Livescope or Active Target, I believe you would really like this mount. Below is a link to the Dub-L-Seat website.
