So I finally broke down and booked a trip with Slade on Lake Fork to go over my electronics. MAN, WHY DID I WAIT SO LONG! I enjoyed every aspect of this trip. I now can see if fish are on piles, size of different species on humps, updated screen and graphics, the list goes on and on. I am now ready to smash some fish. I would highly recommend this trip to everyone, it will definitely give you a better of understanding of how to use and read your unit. Give him a call or pm. It is well worth it.
