I have used a Hummingbird TCR portable for years and I couldn't tell you how old it is. It no longer beeps on fish but, it does allow me to watch the bottom of the lakes up here. Some lakes up here you need something to watch the bottom or it is good by lower unit. Some folks on one of these lakes have summer camps where they live on the lake all summer and still loses a lower unit once in a while. So any kind you get that allows you to watch the bottom is good to have up here.

Also as stated earlier that weeds or other debrie can look like fish on your depth finder.
