Lowrance Elite 4 HDI – GPS Tips I purchased from Amazon – http://amzn.to/1q4vJRq In this video I show off the Lowrance Elite 4 HDI GPS and give some times on how it’s helped me fishing in big water. In open water, you can’t always tell what direction you’re going or how far you’ve gone. So the GPS helps you navigate in big water. You can also pre-set waypoints to fish later. The GPS is also great for helping you see a “pattern” when fishing… as it did when I fished the King of the Island tournament in Pensacola Florida. I was getting the most action in the 32-40 feet of water range. Had I not had the GPS feature of the lowrance, I would not have picked up on this trend. The pattern on the GPS trail says it all.
