I'm looking at purchasing a fishfinder for my 17' Fiberglass boat... I have
looked at the Garmin 160 and the Hummingbird 300TX but I would like to get
some opinions...

Any recommendations? The main features I am looking for a

Accuracy
Depth
Fish
Waterproof
and preferably speed sensor...
I'm not looking to break the bank.

Any input would be great!

Thanks,
