iBobber™ is the easiest to use, most dynamic mobile fish finder and app. The iBobber™ was designed for portability and flexibility—anglers of any skill level and budget can now use our patented technology to see what's below the surface wherever they fish! The iBobber™ uses sophisticated sonar technology to locate and identify fish down to 135 feet deep, depth-tagged and color coded by size. With the trip log you can save GPS tagged favorite hotspots, mapped waterbed contours, water temperature, fish species, photos, and more. You can even get weather, sunrise, and moon-phase information! All on smart devices you already own using Bluetooth Smart® for amazing battery life.
