There really is no info on how far out a dipsey runs.That would depend on lead and speed.We run dipseys a lot once the spoon bite starts catching.But we only run 2 dipseys per side and usually are running them with a #1 and #3 settings.That gives you enough room between them to prevent tangles.A lot of guys run 3 dipseys per side and you have to be A lot more carefully because they are closer together.
A couple of rules when running dipseys to prevent tangles.Weigh your dipseys.Sometimes there can be a difference of .6oz between them.Put heaviest dipseys on inside.That is because when you turn and the inside turn slows down,the heaviest dipsey sink faster.
Male sure your outside lead,#3 setting is always longer than your inside lead,or #1 setting.When letting out your dipsey,make sure clicker on.If dipsey let out too fast will rotate and cause line to wrap around the release.If putting a #3 setting line out over a #1 setting that is already out,move to opposite side of boat so the dipsey has room to clear the line of the #1 setting.If attempting to put that #3 setting over the #1,make sure there is no fish on #1 setting or you will tangle almost for sure.
We also have colored 8" snubbers on our dipseys with color indicating starboard or port side.I think snubbers also help prevent dipsey rotating when putting out due to added weight pulling lure back.I super glued all our rings too since they can separate if tough on them.
I also keep a Phillips screw driver in my pocket to adjust tension on the releases.I want the tension to be just tight enough to hold when running.So speed and choppiness of water affect the amount of tension on the release.I'm often adjusting a lot initially or when rocking of boat causes false releases.
We use #30 hi vis yellow power pro braid on our dipsey rods.Leaders 7ft seaguar 20# flourocarbon.Have been using more spoon harnesses past two seasons too.Takes some time and practice to fishing successfully with dipseys.But they can really catch fish and you can check and reset them pretty fast.Good luck.
