Hey Mel, try doing a zig zag patrol pattern in your designated area. I included this rough sketch in paint to help you visualize what to do. Run in a direction at the most fuel efficient speed which is around 7 or 8 knots I think. Go for 1 or 2 hours in that direction and then stop and descend to 30 meters or so and do a hydrophone check. Then pick a course at an angle to that one and run for the same amount of time and do another check. Continue on the same course and do another check. Then switch back to the original course and do the same thing. Rinse and repeat. I hope this helps, check out THEBERBSTERS tutorial page for more help.
