I used it for the first time today and it was so easy to use and understand I explored some new fishing places all day without the worry of getting lost. I can also go back and catch fish in the same places I caught them today. I would recommend this unit to anyone who's serious about very good electronics on their boat.
It needs to put the hook in the fish's mouth for you to let you stay on shore. If it worked any better it would probably be illegal.
I have watched it mark fish and then see the same witch makes times when they just aren't biting very frustrating, it might be better not to know they are down there!
Some of the best spent money I have ever used. Now for better bait😀
