Is it possible to mount a second screen to my Gen 2 mount?Updated a year ago
Yes sir, you will need the cradle though. It looks like you purchased the bottom only portion of the gen 2 graph.
Here is a link to the product page - https://tbnation.net/products/double-graph-mount-for-large-fish-finders
Once there, select the drop-down for ""Graph Cradle Mount Only.
