My first post to this newsgroup and it is because I recently purchased a
18' Ranger that has a Lowrance LMS-350A fish finder on it that does not
work.

The seller told me that it did not work thus it was not a surprise to
me. I have not had the boat in water but the screen is just random
lines, dots, etc. As the transducer is already installed I would like to
purchase another unit of the same make and model so I can just plug in
the my current transducer and go.

I also want GPS but I am not familiar with what info a marine GPS
provides especially on older units like the above mentioned one. I have
noticed that they must be still quite popular as they bring a pretty
penny on e-bay. If I purchase the one at http://tinyurl.com/2fs46pu on
e-bay what can I expect to see as far as GPS goes? If I am on a river
will it show towns along the way and nearby roads like the GPS units in
our vehicles do?

Another alternative would be to simply purchase a new Humminbird 161 GPS
Fishfinder from Amazon for approximately $190. This brings me to another
question. Why are individuals paying more for old used LMS-350A's than
they can purchase a new unit like the 161 for?

If you would educate me it would be appreciated.

Cheers,

Don
