I am pretty sure the dive chart is in the
Precision trolling Big water addition. it is at the Marina or I would post the chart.

Found this on Greatlakesfisherman.com forum.


Heres what my Precision Trolling 8th addition says for an HJ-12

Feet back/Feet Down
5/1
9/2
13/3
20/4
26/5
40/6
60/7
90/8
A deep down will be different.
