My current riggers have the positive ion control function and yes I do use it. Does it work any better than non ion control...honestly I do not know. There are days when I say "yes absolutely" and there are days when I say "what a bunch of BS"!
I have spoken to some excellent fishing guides on Lake Ontario who swear by it and they have more experience with them than I do.
I guess my final thought would be...while they might not help, they certainly can't hurt!
Love to hear what others think on this also!
I THINK positive ion control is standard for all Canon electric downriggers. I bought my first electric last year (Mag5) and am adding my second this year so this year will be my first running PIC on both DRs. It MIGHT be making a difference. Its hard to tell because catch rates vary from day to day as best lures, depths, speeds all change and have as much or more important than PIC.
I think the difference with the black box is you can "dial in" variances in ion control for specific species, conditions etc. Whereas the electric DRs are static in their setting. I guess I'm saying...if properly "tuned" the black box MAY have greater impact on fishing success than DR PIC. I'm skeptical enough to suggest that I'm happy with whatever the DRs provide and if I want to "up" my catch rate, I would consider other options first like a downjigger/skijigger, better fish finder, kicker motor and my investment for next year which will be an iTroll. http://www.headlightplugs.com/itroll.buy.html
Most important consideration's your boat wired correctly. Faulty wired boat will send fish the other way. Remember that if you're not catching. Capt. Bobby
IM STILL SOO CONFUSED ABOUT ALL OF THIS .
Pro-Troll Downrigger Fishing Techniques explains it fairly well. I'm a master carpenter, so never was very excited about electronics. But sure know that when your boats wired right, the positive ions attract fish. The book explains how to check w/volt meter. Get the book. Cabbalas has them, cheap. Capt. Bobby
Thanks Guys for the great replies!
I'm hoping the Gray Ghost chimes in here also. He seems to have an extensive engineering background.
Considering his past posts running cameras on his DR's and his extensive write ups on trolling LC.
Mike, you made excellent points as did Dan & Capt Bobby. Its hard to tell because catch rates vary from day to day as best lures, depths, speeds all change and have as much or more important than PIC.
I brought this topic up because I'm adding manual DR's and didn't think that PIC would be a consideration.
However I was wrong and think I may have a better understanding now after some research.
Whether you are using electric or manual down riggers the electrical fields are still present due to electrolysis / galvanic reaction caused by dissimilar metals in water. With the aluminum boat hull, stainless steel cables on the DR and the lead DR ball. The key I think is isolation between them.
The only way I'll know for sure is to hook up a voltmeter and test it. Then after taking measurements would I consider maybe adding a blackbox. Or maybe adding a snubber from the cable to the DR ball.
Some additional info.
Sigh whatever happened to tossing out just a worm & bobber? :-)
