I am very confused. What is the difference between downvision and sonar. I see sometimes chirp sonar. I want to replace my depth
gauge and might want a a series raymarine depth
gauge. My deppth guage transducer
has a 2" in diameter thru hull
. I would like to stay with that.
has an a series A68 that uses a CPT110 or CPT120 transducer
and plastic. I think they are Chirp sonar with a 2 inch thru hull
. what would that look like on the screen
? Would I see the bottom in real detail. I don't care about the fish
, I am in a sailboat and am more concerned about the bottom.
If pictres could be posted of both that would make it perfectly clear.
