Great posts and info. Thank you.
I would like to add this quote from the fishfinder city link.
(You don’t have to worry about the sonar unit spooking the fish - they can’t hear it.)
I would be worried about the fish feeling the sound wave.
I am looking for merino wool top and bottom. Clam corp makes a set i just have to find out where i can buy it.
I have a pair of merino wool socks and they are the best.
