Anything fishing

[Drew]

Yes Navionics.
As my old sounder on the boat had no GPS so it was a god send, know it's just for GPS marks when on someone else's boat. Clever.
Considering its a very expensive app.

I reckon it does more than my gps certainly handy. I wish I had some marks for you to "borrow"

I was checking out sonar charts looks nice but not sure if it's needed.
