A non sal****er doesn't work in salt water?? I don't know who told you
that,
but its bull. Go with the Garmin 240. I have one (not the blue) on my
bass
boat and a 23 footer I use for flounder fishing. No problems whatsoever!
In
fact, there is a setting on them where you can specify water type. Fresh
or
salt. I used to have a cheap Huminbird on the 23 footer and it worked
fine
until it died of old age.


Thanks Bill!

Whats the "blue" for anyways? When looking at the spec it has more
power and goes to deeper depth... is that all the difference?
