Try to cover the whole water column, usually 50' to 180' is what I target with most fish being taken at 60' to 90'. Important when you hook - up to know the depth you 're at to duplicate it. Some trips they will come thru at the same depths and at other times it can vary. If you 're using spectra you can mark it yourself with a sharpie, mark mine every 50' to a depth of 200'. Am starting to beleive you don 't have to kill yourself working the jig like a madman all night. If they come thru at the depth your jig is at they 'll hit it even if its barely moving . Have seen tuna caught on jigs off of stationary outriggers, telling me something ? Feel one of the reasons the butterfly method works is because you cover the whole water column . They invented the jig not the common sense to work the whole water column . Yes I dropped a bundle on them also but my favorite jigs are the older raiders in tuna candy . Anything with a slender profile that flutters is what I look for. Hammered diamonds in 6 and 8 oz. work great also as a lot of pers. will attest to. Good luck .
