Truth is .... you have to find'em before you can catch'em, but you can't always catch'em when you find'em !!
Electronics are just tools to help eliminate water where there are no fish, saving your valuable time ... so you can spend that time fishing in potentially more productive spots. The better you understand the cans & can'ts of your electronics, and the more familiar you become with it ... the more likely it will be a beneficial factor in your fishing experiences.
