I can tell you my 2015 1st gen Terrova does not have the accurate spotlock. It’s fine for big water away from obstacles, but when I’m in a creek, close to structure, it is more trouble than it’s worth. I’ve been told by people that have the newer version, when they are fishing in my boat that the new generation spotlock is light years ahead of mine. I’m going to start saving for the new one, but will stay with this one in the meantime. My advice would be to get a gen one if the price is good enough that you can get your money back out of it after you save the difference up for the new one. At least then you can get some of the benefit while working toward the ultimate goal. Just my two cent...
