How accurate is a commercial sonar down to 2400 ft.? Doesn't the accuracy
get effected by enviromental issues like: salinaty, water density, temperature,
inherent accuracy of equipment design (sonar), and calibration of sonar. With
all these factors how far off could they of been? 100ft? 200ft? Anyone have a
guess, I don't.
