I'm not sure how big the lakes are you fish on..
but for a few bucks more, up grade to the egale with
the GPS unit... Eagle FishElite 480 Fishfinder/Mapping GPS
these units allow you to map out and put in waypoints to
good spots so you can get right back on them... '
I can't tell you how many guys wish they had spent only
about 60.00 more for this feature......
also check out this site for units as they have replaceable
transducers and units for very cheap.....
also another plus for gps is that you can run in the dark
without worrying about the banks....
