I am looking at the Raymarine Element 9's and really like the hypervision shots. With that said, I would like to run one on the front of the boat and one at the console. Can these units be networked together to share waypoints. Also, does anyone have the model number for their GPS antenna so I can see position of the boat. This is essential when fishing in deep water. Is the puck the Raymarine RS150 (E70310)? I am pretty familiar with lowrance electronics and thinking about making the switch. Thanks for the replies in advance.
