Setup perfect for a sonar shot. Kept updating range, must have pinged the ship 2 dozen times, had angle of the bow set - knew the course and set up via tdc, took speed measurements - 4 times via mark, wait 3 min and mark again then measure distance. It was night and pitch black outside so sonar was the only way.
As you can see from the pic the range was way off, the speed was way off... I don't understand. :hmm: :hmm: :hmm:
When I saw this happen I thought there might have been two ships so I went back to the sonar and tuned around the dial but only picked up one contact.
