Thread: 798 Left side screen issues

I get the exact same line on mine. It looks to be clear but I think mine is maybe blocked a little. I was going to try to angle the transducr down a bit to see if it helps. Your pic looks sharper than mine what other setting sre you using.

Not Much else on the settings. Been keeping My SI range around 75 feet. That helps with the sharpness. Mostly fool around with SI enhance when I am messing with settings. The pic with the Amber color that has the Menu at the bottom, that is how I keep it when searching structure. Turn sharpness up to low or medium when looking for fish. That sharpness will sure make the pic look grainy when turned up too high but sure makes the fish pop out at You.

make sure Your boat speed is matched close to Your screen speed. Other than That, I don't know.CF

Is this issue always on the left side...??

Odd that it clears up occassionally...

You might try temporarily monting the xducer to a pole or broom handle and stick it farther down in the water to test if it is the jackplate for sure...

Yeah, It is always on the left side. I pretty sure I am getting some blockage from the jackplate. When I do a line of site from the ducer to the jack plate, it is so close that I can't say for sure if it is getting a clear line or not and if it is that close, then I would think that that is what it is. Planning on grinding a little of the jackplate off to help. It won't hurt the plate as there is plenty of meat there to get rid of. Just need to shave a quarter to a half inch off and there will be clear line of site. BUT, the thing does come in clear on that side from time to time. Might need to try the ducer on a piece of pvc pipe. Don't know which route to take exactly yet.CF

Just a note to say mine started doing same thing on my new boat after dealer lowered the outboard one hole...I thought it was motor...After trying it with motor completely up and out of the water and moving the transducer...someone mentioned try re downloading the current Humminbird update and it cleared up.....don't ask me why but it worked and might be worth a try.

Thanks C&C. I have not updated mine since I got it. It still has the 5.4 version on it. have been planning on doing the update to 5.8 and that will be the one that I can save. Have any idea what the difference between the two versions are?CF

I've got an 898 and it's currently running update 6.18...here is the page link explaining the revisions that Humminbird puts out with the 6.18 update.....Worth a shot

Oh Yeah, I forgot that I also have my settings set for shallow water and salt water because I fish mostly at 20 feet and shallower. Might help if You get a crisper picture if You are fishing shallower water like I am.CF
