Howdy brothers, on my boat I have Lowrance LMS-350A GPS 200x320 Black/White 192kHz it has the optional speed and temp sensor on it also. I was just wondering if its a good fish finder or not? I know back in the day it was a good one. I am guessing those are pretty low pixels 200x320. I don't know how to read a fish finder yet so its all new to me. I was just wondering if I should upgrade or if this one is good enough to pick up those cats laying on the bottom?
