Lowrance GlobalNav 310,(old) and a Garmin E-trex, the camo one with
the sun/moon calculator in it. I mainly use the 310 fishing, when I see
something of interest, or get hung up, I mark it. Also mark when I catch
fish, after awhile doing this in one spot, I started to see some curious
patterns develop, like fish catches strung out along a line across what
looks like a featureless flat on the depthfinder - maybe a subtle depth
change or old silted in creek channel that doesn't show up easily or at all?
Go by it for my trolling speed, too.
