Have no experience with the 967, but I pretty sure the answer is going to lie in the sensitivity and noise rejection/clutter settings. Try running them up and down for the best combination - the more more sensitivity the more clutter.

Past that, try keeping your jig in the very center of your transducer beam. You might even try tilting the ducer slightly foward to project the beam in front of the trolling motor slightly to make it easier to get the jig into the beam.
