Hi all...I've been thinking about it the last few days and came to the conclusion I'm way behind the times when it comes to this electronic stuff. Can anyone tell me if there is an affordable way to get into the Lake Master/Navionics chips with out selling one of my kids. I have a small 14' alumium with a 15HP Evinrude so I'm not running and gunning big lakes and I'm not fishing dozens of lakes around the state. There are several lakes around the city here I like to fish so I'm wondering if these products would even be helpful. Can anyone give me some advise on the type of unit I should look at for a resonable price and then I can decide on what type of chip I'd want to go with.
