I have a 1022 dedicated to livescope on the bow. No complaints. I paid $825 for it used and it is much clearer than the 93sv model due to more pixels.
The 1042 has a transducer option if you want to go that route. I would like to have maps at the bow occasionally. I have a Force with di/si built in and have never used it once for sonar! Livescope is that easy.
There are several garmin groups on Facebook with a wealth of knowledge!
