Deep Trolling?

[costalsteel]

Randy at Tahoe Rod works here . with couple of suggestions :
Can get a gunnel mount rod holder. That will work with scotty small dowrigger with 3 lb balls . It is the same as the rod holders .

Another good way light sinker releases and use ball sizes 6 oz to one lb. This works good for kings on most places easy control to a specific depth . As you would in the ocean king fishing .

Long lining with lead core is not a good way in most places because of most people fish straight down with downriggers.
Does not work very well in areas with a lot of boats . But you will loose the balls

I build a lot of specialty downrigger or the guys at Tahoe & in Northern California . Rods for Inland Kings & Kokanee for smaller sit down boats bigger boats as well as larger / longer for stacking . I have look at this kind of fishing in great detail over the years .
