I fished out of a Garmin sponsored boat last season during the Governors Cup and I can tell you that Garmin is the real deal. At that point they hadn't partnered with Navionics yet so the mapping wasn't the greatest but the sonar was incredible. Their side/down imaging quality was better than anything I've ever seen on the water and I've fished both lowrance and bird units with my boat running lowrance. The boat was also equipped with panoptix and it was awesome watching down or back and seeing in real time what was about to happen. In my opinion Garmin is top notch and will definitely be on my next boat.
