New to Bass University and had a question about mapping a reservoir. Is it possible to actually map an entire body of water? Like actually save it and then say take it over my grandfather's and we can scroll through the whole thing? Study it? The elite7ti is my first ever sonar and I just bought it a week ago. Lol..so I'm clueless when it comes to any of this. Thank you in advance

Awesome! Way to go with your gut. BTW I'm addicted to top water!!!!! Lol
