Hammond's sells it. They sell Bass ProShops brand too. $$ well spent. Takes a little getting used to, but (from what I understand), it's easier than using downriggers (less to deal with).
I'm always happy to share what is working for me. I'm not one of those fishermen who hide what they are doing (when/where/how), so if you ever need any tips, feel free to ask.
I enjoy helping others catch fish ALMOST as much as I like catching them myself! Boating (fishing or just cruising), I think is a community affair. The more the merrier, I say!
Also, if you go by Hammonds, pick you up some Chipmunk's white bucktail jigs... either 1 oz or 1 1/2 oz. They say 1 oz. is working 9 colors out doing 3mph, but I've gotten the 1 1/2 oz. ones as sometimes it's hard for me to idle at 3mph unless I've got a little headwind. 3.5 seems to be the speed for me, so the heavier jig helps get it to depth, I think.
I've been marking fish around 35' deep on average. Running the jigs just above the fish is producing for me. I'm still learning the leadline/depth/speed think now. I've only been doing this for 4 weeks now, but I must say, I'm not doing THAT bad! :lol: 8)
