Fish finder advice

[dubob]

finally have my decision on a fishfinder for my boat. A fellow co-worker gave me a lowrance elite 7x finder that he had taken off of his boat.  Couldn't beat the price.  Just ordered a transducer and a power cord for it. We'll see how it goes.  Thanks for all of the advice.

I have the same unit on my ThunderJet.  Bought it at a Cabela's Bargain Cave in Texas for under $500.  The previous owner had mounted the transducer on top of the mounting bracket (pointing up) and brought it back to them.  Been working great ever since I installed it with the transducer pointing down.  ?
