I have had a 2.0 for a couple of years and it saves my bacon all the time. I use it for checking holes and looking for fish. I use a 5.6 while fishing as I like the zoom. I sometimes blow a fuse and don't have a spare and the 2.0 works great (runs of AA batteries). Also when new folks come out and don't have a graph I let them use the 2.0 and are blow away. Last year I got a cradle for x-mas and really like how that works. Add a float to the transducer to keep it from dragging down the hole.
