ReelSonar is a small company based in Seattle, WA. Developing iBobber sonar from the medical ultrasound, ReelSonar's founder Alex Lebedev and engineers were able to develop a powerful and much smaller sonar and, perhaps most importantly, a much less expensive one.

ReelSonar's mission is to ensure that the tradition of fishing and all of its tools are available to everyone, regardless of income or boat ownership. Over half of the world's anglers do not use boats, leaving them at a disadvantage compared to those that can afford both a boat and a boat mounted fish finder.

iBobber is available at retail locations worldwide, including Cabela's, Dick's Sporting Goods, Academy Sports and Outdoors, Decathlon, Argos, Marks and Spencer, as well as smaller retailers.

Folks can also find us online at a variety of sites, including Amazon, Walmart, and In addition to iBobber (SRP is $99.99), ReelSonar also makes two accessories: the unique and utilitarian pliers/multi-tool and an easy to use digital scale with built-in tape measure. These ReelSonar accessories retail for $19.99 each.
