I really like my over the side transducer deployment arm. I used a Mad Frod Mini Liberator to mount my new Humminbird 385 ci DI. Due to the way I store my boat upside down, I needed to be able to pull my entire fishfinder setup out of the boat, so you can see that I have the extra power and tranducer cable coiled under the Liberator base (I had seen others do it this way). I'd love to be able to do something different with the cables, but I can't figure a way to do that with how the connections work on the Humminbird quick release base. Also, once I learned about the availablity of the 587 ci HD DI unit with the larger screen (this unit was mentioned in another post on this forum), I upgraded and just switched out the new 587 head unit. Works great!
I don't think the cables detract that bad. It looks like a setup that's easy to setup and take off completely when needed. I was out this morning and my 385cd DI works just fine with the thru-the-hull mounting kit.
Great to hear the 587 worked out for you.
