How deep of water are you going to be fishing? I have a Lowrance elite 7TI and it works really well. I swapped out the transducer for a 50/200, Low/High CHIRP because we often fish in pretty deep water. It also has downscan which is pretty cool but I honestly don't use that feature that much.
Do you know what the previous owner had for a sounder? I made the mistake of buying the wrong transducer the first time, now I have a $200+ transducer with nothing to use it on. Oops.
Fishing in that 8-15 foot range. Do you have any suggestions? I don't know what the previous owner had for a sounder. But I had a bit of installation experience from a friend, so I think it will be fine.
