Yes the seat is very comfortable. Old Town listened to the anglers and added some new designs that make the new sportsman 120 pdl a real performer.I am going to add my Garmin Stryker Plus 5 cv today and install the transducer.
The kayak has a universal mounting plate. My garmin transducer transom mount bolt pattern fits the plate and the cable runs up through a dedicated scupper hole. I will be drilling a hole to run the cable into the front hatch area and then another hole near the track to connect the power and transducer to the garmin. The fish finder will be mounted on a RAM track mount. I am using the hobie mounting kit for securing the cables and keeping the compartment somewhat dry.There are some good videos on you tube that show this type of install.
