Getting more accurate on your longlining

Have any of you tried turning your transducer facing out away from the boat to try to get a reading on what level your jigs are traveling at. In thought it seems like it might work but not sure.

Sonar only measures distance to the reflective object (by a time equation)...and echo strength (by how much of the sound pulse is returned to the xducer)...

It would show how far the jig is from the xducer (measured laterally-but displayed as depth on the display)...but not how far the jig is from the surface or the bottom (vertically in the water column)...

Now...if you can figure out a way to get the xducer to ride directly above the jig...this would show you how far down in the water column (depth) the jig is traveling...(because then the distance from the xducer to the jig would be equal to the water depth of the jig...minus how deep the xducer is in the water)...

It would only tell you how far from the transducer the jig is. That is also true if a fish is not directly under the boat. If you pick up a signal that is out at the perimeter of the cone, especially in deeper water with a wide cone, it might tell you the fish is 40 ft deep when in fact he could be 25 ft deep, but 40 feet from your transducer.
You might get a buddy to run behind you and his DF might pick up your jigs under him. Then you woudl know how deep they are.

Yea I thOught of that after I posted , wasn't thinking. Maybe get somebody to ride over the jigs with their df

This would work...

Before the Trollers Bible came out we would find sand flats, using line counter reels we would make passes with different lures and different depths taking notes at what lengths lures would touch bottom.
