This is interesting before yesterday I had thought that if you wanted to scare off fish you'd be in the ultrasonic range or have a sudden noise. Instead it's down in the lower end of sound that we can hear.
I'll have to think of how, if at all, this affects equipment selection.
Juro, I know that sound
. The other sound that crossed my mind was those on the day after someone served beans and sauerkraut for dinner
while camping. For some reason Ive never caught much on those days.
