I was about to pull the trigger on a new Lowrance Gen 2 HDS unit when it struck me that it's possible that a Gen 3 is coming soon which would save me some money on the " obsolete" Gen 2. Does anybody know about plans to introduce this product soon? I won't be back in the USA until February 2015 but I'm looking to move on this for my kid's sake, hoping they will figure it out and be ready to tutor me when I get back. If you can steer me to the least expensive place to buy that would be a bonus. Thanks guys.
