Losing my jig in last few feet before bottom??
« on: Jan 29, 2021, 07:18 AM »
My flasher seems to be working fine, but the flasher appears to be showing the bottom roughly 2-3 feet above where it actually is..   My jig continues to drop after it ‘disappears into the bottom’ for a few feet. 

Any ideas??

Hummingbird Ice 35, roughly 45 ft of water...

Thanks in advance for any comments.

It could be a few things.  Bouncing off a nearby rock, could be on a drop off, or you could be above a really steep angle which would read only the shallower part of the angle.

VT - thanks for the reply.  Good thoughts. I will try moving the hut over a few feet to see it it improves.  I am located on rocky and steep drop off.   

Thanks,

K

Not sure if the Hummingbird has a "Gain" feature, but that could also be an issue.

If you can narrow your beam yo may pick up your jig ..narrow beam and deep water go hand and hand .

I have an Ice55 and Son has a 45, even though we don't have a 35, I think all Hummingbird flashers work the same.  Having said that, I would check the things noted above.  Mainly, is your transducer hanging level in the water.  I have had experiences where it wasn't reading correctly and I pulled it up and noticed that it wasn't level.  The two cords weren't level, making the transducer to sit cockeyed.  I have found sometimes just taking the ducer out of the water and putting it back in fixes the problem.  Another factor is the gain.  The more gain, the more it picks up.  That can be a double whammy, the more you turn the gain up, the better you see your jig, but the more interference you get from algae, plankton, and other things floating in the water.  Then there is the cone, as stated the smaller the cone the more power there is going to a smaller area, making the unit work better in that smaller area.  Making sure that your transducer is just below the ice will help it see better.  If you only put the transducer in the water and it isn't under the ice, it might not work properly.  Then of course is the jig itself.  I have found that tungsten jigs show up better then lead, obviously because they are more dense.  And, the bigger the jig, the better it shows up.  So, the next time you are having problems, try changing some of the above until you find what helps get a better picture.  Hopefully, this helps!  As Always, Take Care and Stay Safe.

Thanks to all for your suggestions.  Much appreciated.   

Will check to make sure transducer is hanging level etc. 

Sounds like my lure is in the dead zone ( great article - thx).  Right now hut is situated on a drop off.  Will be moving it tomorrow - so will see if this helps.  Might need to see if there is a narrow beam transducer available for this model. 

Thanks again for the comments.

Its a dual transducer I believe

Yes, you should be able to switch the transducer from wide angle to narrow, changing the cone size, using the "beam" button.

It is a false bottom. It is some form of structure that is higher in the column. Usually a boulder or a ledge. Sometimes a narrow cone will help, and sometimes a small move is in order.

It's a cone picture, just to the left of the depth #'s.  If you have it on wide, a big cone will be just below the top line, above the depth #'s.  If it is on narrow, there will be a little cone, just above the line that is just under the depth #'s.

 I can read through a dead zone with my marcum lx7 ,and my helix 5 takes a little getting use to and that’s on graph mode , I could never read through it with my vex nor my older lowrance

I tried changing the beam setting and it didn’t help.   

Moved the hut and the issue is gone.  Must have been a rock or something at the old location. 

Thanks for all the advice!!

A tiny bit of current can swing your jig out of the cone.

Ive noticed a deadzone on my helix 5 the last two times Ive been out. I doubt it was a large rockpile or something both times. Ive been i pretty flot areas. Fishing 15-18 FOW, my jig shows on bottom on the screen and then i feel bottom at least a foot or two lower. I tried changing the cone angle, but it only has 2 options and neither helped.

For anyone else with this problem, its definitely a ledge or rock or something. My humminbird in narrow 9deg beam showed bottom at 30' yesterday. I dropped my spoon down and decided to bounce bottom, it kept going.. and going... and going. and going. We grabbed the camera and dropped it down, we were on the edge of an old bridge.. Camera never did reach bottom, so it was more than 50 foot down off the edge and my screen said 30.
