Its great...when its connected
I use this with my iPhone 5s and iPad 2 both updated and un-jailbroken. The Deeper will connect to my iPhone, but constantly looses connection. It will not connect to my iPad at all. I fish lakes and inlets where waves are minimal so that isnt the issue. The Deeper just isnt very connectable. I havent caught anything using it, yet.
