Trying out my new iBobber by ReelSonar today at a nearby pond (at 8 months pregnant I try not to venture too far...lol). The sonar feature is extremely useful and ...more accurately shows the depths and vegetation. I was able to catch a large amount of Bluegills, Pumpkin Seeds and Perch that were tagged using this awesome feature. Looking forward to getting back out there & trying out the waterbed mapping in a larger body of water. So far I am extremely impressed by this product!
