CP,
This is the same device that another Humminbird owner asked me about more than two years ago. I did not know than and I don’t know now if it would work or not and asked him to let me know either way if he bought and tried one. I never heard back from him. I’ve had unconfirmed reports that it will: “my friend’s son-in-law says he knows someone who says it works”, sort of deal. Why not try it out for everyone here. I know you will give us feedback one way or another!
