YES!! Even if you do not spend the time to fine tune it
to spot fish it is well worth the $$$ just by the ability
to map the bottom. You find all kinds of rocks, trees,
cars etc... Also IMHO it is priceless because you can
find dropoffs, flats and river channels for staging
fish. I use mine everyday on the water and I usually
don't plan my day thinking I am going to go fish this
point or that point but rather I am going to go fish
that submerged rock or that submerged tree. Wonderful
tool!!

Good luck.
