You can also add all the detail from,Google earth on the lakes you fish to the new units now. Just make sure you only add the detail around the lake. There's instructions online for that. I read it but figured it was over my head.
And as Canepole posted I love the History bottom left on mine. It allows me to see some of the drawdown lakes. With and with out lots of water. Nice to see all the stuff when the lakes are drown down say 30 ft in winter time.. Now to be able to get Google earth in real time. That way you can get a fishing report from home any time anywhere.
