ReelSonar iBobber Wireless Bluetooth Fish Finder

The ReelSonar iBobber Bluetooth fish finder casts up to 100 feet from shore and sends live depth, fish arches, and bottom structure data directly to your smartphone — a compact sonar unit that turns any rod and reel into a fish-finding setup without a fixed transducer or a boat mount.

ReelSonar iBobber Castable Bluetooth Fish Finder for Shore and Boat Anglers

The iBobber uses CHIRP sonar to display fish at depths to 135 feet, distinguishing fish from structure and showing their position relative to the bottom in the companion iOS and Android app. The cast-and-retrieve design works from a dock, bank, or kayak without installing mounting hardware — useful for shore fishers scouting a new body of water and anyone who wants fish location data without a permanently rigged transducer. Integrated GPS tracks depth changes as you retrieve, building a bottom contour map of the area you're working across multiple casts.

• Casts up to 100 feet on standard spinning or casting gear — no permanent mount required
• CHIRP sonar reads fish and structure to 135 feet with fish arch display in the app
• Pairs with iOS and Android via Bluetooth — live sonar data on your phone screen
• Integrated GPS maps depth contours and logs fish strike locations during each retrieve
• Up to 10 hours of battery life per USB charge for a full day of fishing

At $128.99, the iBobber gives shore fishers and kayak anglers electronic fish-finding capability without a $500 fixed transducer. An effective tool for locating depth changes and fish-holding structure on unfamiliar water from the bank.
