Got the Helix 5 for my Ocean Kayak Trident 13. Installation was a snap. Battery in battery holder, monitor installed in monitor compartment, transducer in transducer-ready scupper hole. Only needed to drill two one-inch holes for wiring, sealed with goop as recommend.
A great unit with multiple screen and viewing options in color views, with side by side GPS and depth/fish finder views available. Adds so much utility to my boat I can't believe I waited so long to install it.
