1906: Sonar technology first developed to 'see' underwater
1962: Researchers discover predatory fish can be called with certain frequencies
2016: ReelSonar combines the two technologies for an unbeatable fish finding tool: iBobber Pulse™ with FishSiren™

Watch out, Fish, it's our turn!

iBobber's newest feature is called FishSiren™ for a reason; named after the mythical Sea Siren, FishSiren™ taps into the 'ears' of predatory/game fish by mimicking the vibrations of prey, luring them in.

iBobber Pulse with FishSiren

This 'ear' is called the lateral line and is present in most predatory game fish, including bass, crappie, trout, catfish, red fish, stripers, flounder, drum, snook and bluegill.* Though the idea itself of calling fish is not new (around since the late 1950's/early 60's) we knew we had a way to maximize its potential as well iBobber's. Now you can call fish with the tap of your finger, as well as see them, waterbed contours and depth, and everything else the original iBobber™ can do.** Now there's no need to spend money on a separate fish attractor unit, or different fish calling lures anymore! As with any of iBobber's features, you don't have to use it, but it sure is nice when you want it.

Whether you are a conservationist, kayak, shore, or river angler, travel for fishing, or just want to be the first on the dock with the coolest gadget, the iBobber Pulse™ with FishSiren™ is for you. We hope iBobber Pulse™ will also engage new and young anglers by speeding up the process of learning the many factors involved in catching fish.

*If you are interested in learning more about the use of the lateral line, there are many resources. Here are a few:

**The FishSiren™ cannot be used at the same time as the bite/strike alarm as the alarm relies on vibrations to identify a bite/strike.


Find more fish with sonar depth up to 135 ft, covering 243 feet diameter at the waterbed and the highest angle (42°) on the market. Choose from raw sonar or fish tagging modes.


A built-in vibration-based fish calling device at a frequency of approx 100Hz, 2 pulses per second.

Love at First Cast

The castable wireless fish finder that syncs with your smart phone or tablet

Designed with portability and ease of use in mind, iBobber is the best personal fish finder for fishing from shore, bank or dock, and is ideal for kayak, canoe and float tubes. It works in either saltwater or freshwater, and is very effective at locating fish and structures on ponds, lakes, streams, and rivers.

The free app syncs via Bluetooth Smart™ to map waterbeds, GPS mark spots, log water temps and depth, and allows you to document lures, species, and photos in the trip log. Fish are displayed by size and depth to get you on the lunkers fast. Great for finding smallmouth and largemouth bass, panfish (like crappie and perch), salmon, trout, walleye, pike, muskie and other game fish and edible species within 135' depth.

The built-in LED beacon, and the strike and fish alarms, are invaluable for ice fishing, carp, and night fishing. The high contrast design increases visibility in bright lighting, and the app includes an anti-glare setting for extra control.
