positive ions from the water

5 posts in this topic

Does anyone follow the concept put forth by one of the down rigger makers,that proposes that the electrical current picked up by the down rigging cable can be either too excessive ,or possibly not quite enough?In reading their booklet, It is said that the ideal voltage is .07 volts.Easy enough to check, but is it something that is a factor?Pheramones,chemicals, and various other things will effect fish,but this has me wondering what the heck?

The Pros say you cant pay enough attention to details and

the "little" things. To me this seems like one of those "little"

things. If I was buying riggers I would listen to what the

salesman had to say about positive Ion control, buy the rigger

and forget what he said by the time I got home.

Could it make a difference in a fish or two over the course

of the summer? Maybe.

Let us know if you find out something concrete.

If you get into the great lakes or saltwater fishing web sites you'll hear about this, an electronic box that controls the voltage between your rigger cable and your boat, keeping the cable at a certian voltage.

According to a trolling book I read:

You check this with a voltmeter, one probe on the rigger cable when its down, one on the engine ground.

You want to see between .55 and .7 volts. (Where did you get the .07 number?) This has been proven to have a positive effect on fish take.

If its lower, you would benefit from the black box bringing it up. If it higher, its driving fish away, use the box to bring it down, and something may be wrong with your electrical system.

This can also cause corrosion problems for your motor. Potential for problems is a lot higher on aluminum boats than fiberglass.

You'll find species specific voltages in trolling books. Most are geared for salmon or saltwater species but I gotta believe walleye are no different.

So, Id say the rigger mfg is not pullin your leg.

Honestly I believe in this technology. I have been downrigging this lake a long time and I have never used the black box or checked the votage in my cables. We catch some fish but I have to believe we could improve our catch by using pos ion contol. I will be bring my voltage meter this year to see what voltage I have on my rig.

The .07 was a brain hiccup! thanks for the correction 2

      It was a main lake break line that went from 18' and dropped into around 30'.  Just a sand transition into mud.   The fish we kept were loaded with small perch and crayfish.

      For winter jigging with Raps I cut off both front and rear hooks and upgrade one size on the middle treble hook. Cliff

      Another observation from the tournament and pre-fishing: On LOW I don't usually get very concerned about colors on cranks. However, Friday and Sat, the UV white with pink striped top shad rap was doing about 6 to 1 in the mornings. Afternoons, the gold foil rap was by far our best color. I'm a bit color blind, but pretty sure that UV rap has pink on the top. Wonder what fish actually see...........not much pink striped stuff swimming around the big lake.

      1/18 Day 4   Day for was exploration Day for the family.  Amanda, the kids, and my mother in law spent a good portion of the hanging out in town.  Shopping and visiting a few of the local attractions.   The father in law and myself decided to pull his boat and go explore a near by lake we have been thinking about.  This would give us s little change of pace.   Fishing actually exceeded our expectations, especially for starting in the early afternoon. Unsure where to start we motored around watching the graph if an area I thought might be good.  after a short while we noticed most marks showed themselves in 18-21 ft on steep breaks.  With the winds blowing we decided to try anchor on top and let the wind drift us over the and bobber fish.  This began to seem unproductive after about 45 mins with no bites, yet we were marking fish.  Out of bordem I decided to raise up 5 ft and cast as far as i could to the top of the break (15ft).  The first 3 casts produced 3 walleyes 15"-18". The bobber never settled before they went down!  The walleyes them slowed but the perch bit really picked up.  Most perch where 9" but a few went as big as 11".   After that spot slowed we hit a few similar spots until we settled on a spot bit deeper but with lots of marks.  This spot would give us pretty non stop action till dark.  With different species rotating through. By the end of the day we caught: 12 walleyes ranging from 11"-21". 5 Pike 20"-30" and one really big one that bit a 10" perch as it was being reeled in by the FIL. Countless Perch, not many under 9"or over 10". And a few dozen bluegills 7.5"-10".   Service here is giving me fits with photos. Hope to post some when i get home this weekend

      Perchy - Insured?  If so, the adjuster will have some recommendations, off the record, on places for repair.

      For all you jigging rap fans out there are you generally jigging those vertically or on the move.   I seen some discussion earlier on the front hook and one thing that I have heard about that hook is a lot of people do take it off in order to prevent snags. I have donated quite a few jigging raps in the past to rocks on the big V I have donated quite a few drinking wraps in the past to rocks on the big v

      Help! I need to get estimates to have the transom repaired/replaced on my 2002 Lund due to an accident and have no idea where to go? I live in Owatonna. Thanks in advance!

      Not on mine either!!

      Every store is different as to what they have in stock so if your looking for a specific thing in your size you might have to hit a couple. I went to the Duluth store for my bibs.   Yes a lot of the stuff is still too expensive for going out of business sale prices.
