Way to many to post but you can check out real saltwater screen shots from my boat, here...

I have a B175m through hull transducer. The Axiom Pro has a built in 1kw chirp sounder built in. I have screen shots holding bottom at 1800". If you can operate a smart phone you will have no problem using an Axiom Pro.
I run Axiom Pros on my boat.
