The Harmony SlideTrax Nano Liberator is a transducer deployment arm that flips up and rotates to quickly raise your depth finder transducer up and safely out of your way. Twin anchor/pivot points allow you to fine tune the extension and provide consistent positioning of the transducer arm in use. The Nano Liberator installs and removes in seconds. It's compatible with Wilderness Systems Slidetrax and YakAttack Geartracs as well as many other ¼" tracks. Attaches with a wide range ofquick release hardware including YakAttack Screwballs (sold separately).
The Nano-Liberator works pretty good if you would like the option of easily raising and lowering your transducer. I'm not a fan of mounting it in the hull but also don't want to damage the unit so this works well for me. In my opinion, it could benefit from a slightly larger plate so that 2 screws can be used to attach it to the track systems but I didn't really have that much of a problem with it turning sideways on me.
