iBobber can now display fish detection and depth info on your Apple Watch!

Love at first cast. The fishfinder that 
syncs with your iPhone or iPad.

There’s a lot to love about iBobber™. It syncs via Bluetooth® Smart (Bluetooth Low Energy Technology) with your iOS device up to 100’ away from a boat, shore, kayak, or pier, so you have a fishfinder with a solid connection, that won't deplete your phone's battery like wi-fi does, a fishfinder that goes up to 8hrs on a charge, that's half the size and weight— a fishfinder that’s as mobile as you are.

The Bluetooth Smart standard is different from the Bluetooth® used in other fishfinders.
Bluetooth Smart is designed for short messages from nearby devices such as temperature sensors, proximity sensors, and medical devices such as heart monitors, and now sonar signals.

The iBobber app in conjunction with the iBobber bobber (sold separately) enables you to locate fish up to 135’ under water, GPS Tag favorite hotspots, map the contour o waterbeds, and measure water temperature.

You’ll love that you can save all your fishing adventures with the Trip Log, and share them all on social media. You’ll also love the Lunar Calendar, Fish Alarm, Strike Alarm, Bobber Beacon, Weather sync, and the app’s stunning graphics.

iBobber is for anyone who loves to find fish, and wants to catch more of them.
 Just cast the bobber (sold separately) and Ping! the iBobber app syncs via Bluetooth Smart and displays where the fish are.

The iBobber app is designed for one-handed use, and can help make fishing more fun 
than it's ever been. Even if you have a boat-mounted fishfinder, iBobber can free
 you from seeing fish only under your boat.  And finding more fish is always a lot
 more fun than just fishing!

Customer Reviews

Works but requires a profile

Ok seriously, it's not too bad although it does run down your phone battery. My biggest complaint is that the app requires you to create a profile. So if you wait until you are out on the lake in the middle of nowhere with no cell reception then it's worthless. How about a "maybe next time option" or "skip this step". I know the whole reason for the profile is about data mining but seriously! There are other products like this now that don't require a profile so how about?
