The next time you go fishing, you won’t have to guess where the best spots are if you have an iBobber. The iBobber is a small castable fish finder that works with your iOS device to show you where the fish are, how big they are, how deep they are (up to to 135ft) and even map the bottom of the waterbed. The iBobber uses sonar and Bluetooth Smart which allows you to cast it up to 100 feet away and still see a live view from your iPhone or iPad. The free app will allow you to keep track of your favorite fishing spots using GPS and make notes in a trip log so you can remember your adventures. The iBobber runs for about 10 hours on a rechargeable battery and comes with a special USB charging dock. The iBobber has a list price of $99.99, but is available at a lower price from retailers like Amazon. For more info visit reelsonar.com.
