If they cant be made while fishing, i doubt i could ever sacrifice the time to do it myself, i never stop. I go straight from fishing right into hunting. Man that sux because that is a really cool feature, i guess i will just never get to use it. Fished today, and realized just how much easier staying in a channel would be if i had a chip! Its not impossible to do tho, because I had an outstanding day, but sure would make things alot more pleasant! Maybe in my lifetime all the lakes in arkansas will be on it and i make the investment then. Or maybe they can make custom cards saying we have all these different lakes. Choose any 5 that you fish and we will put those on a card and send it to ya lol!
