I had an iBobber which was pretty similar and honestly never used it. Too much fumbling to keep the connection to my phone and the features were basic. Deeper is a nicer version but for half the price you can pick up a Garmin Striker 4

Seems kind of gimmicky to me, but it has pretty decent reviews on Amazon, so it must be working well for some people...
