A few more code breakdown
RRF ....ripplin redfin
RR ... reef runner
NK......northern king
SS .. ...silver streak
Dipsy
Size s 0 , 1 , mag......larger # = larger size and capable yo go deeper
Setting...1 , 2, 3.....higher # ...shallower running ....but furthest away from boat
Distance back.....amount of line from rod tip to dipsy......on a size 1 deep diver or dipsy with ring on.... can generally go with a 1/3 depth - line amount, for running guestament ......ie 90 back should be close to 30 ' down
Many variables ....line diameter , trolling speed etc...
Riggers .......25 back, down 40, over 58
Breakdown...lure has 25' leaď from release, rigger set at 40 ' down in 58 FOW ...feet of water .....realistic your lure would be around 30 -35'.....exspect 3-5' of blow back on your cannon ball......depending on lure type espect some float up....with spoons, worm harnesses, floating rapelas..... any none floating lure with a lip ...wont have float up...but dive down.
So longer leads will change running depths of lure.
It's all best guess ....take info from posts as starting points ....experminent and change regularly.....and repeat once successful
