I think they go shallower the faster you go because dipseys will sink so they are speed dependent as well as a diving device.I know running colorado blades on harnesses at 1.5mph and slower on a 2 setting cannot let out much more than 150' or we will drag bottom in 72'fow.Also the slower you go the less separation you get between the dipseys running them 3 to a side.
They dive based upon resistance. The luhr jensen depth chart is based upon a 2.5 mph troll and the depth will increase by 10% for each mph faster troll. Will post the reference link shortly. I have a printed copy in hand.
They drop like an anchor when the boat stops because of the lead. But the lead is for the direction.

They absolutely run deeper the slower you go...shallower the faster you go. At rest, they will be straight down, because of the lack of water resistance...just like anything you pull through water, the faster you go, the more resistance. There's really not much difference between a bottom bouncer and a dipsey except the dipsey's ability to plane out.
Thanks guys i have some good input to go off of tomorrow i was told i need to go deeper so i think i will drop my 3 setting to 180ft. instead of 150ft. and see what happens!! Last time i couldn't pick any up until i picked my speed up to 1.9-2.1 mph gps speed but i think i was above them most of the day!! Thanks again!!
[QUOTE=Papascott;1475566]Trolling depths will increase/decrease by 10% for each 1 m.p.h. faster or slower. Line diameter and lure or attractor drag can also affect depth reached
Papascott, here is a question for ya. How much drag does a 8" spin doctor add to a #1 dipsy. I was wondering that when we were in ollcott. What percentage should I add to my lead lengths to reach the acquired depth on the chart.
When I was running a dipsy spoon next to a dipsy spin doc and fly combo, the combos line angle was a lot higher than the spoon.
