Thread: Humminbird sensitivity

You are correct on the water conditions contributing to the setting numbers of the contrast and sensitivity of the helix unit.
I’m normally around 50% on both and will adjust according to the water conditions. Dirty water, agitated(wind blown) water and hard water(still/clear water) all have factors that effect the return picture. It seems I’m always messing with the settings to get the pic to “pop” and more understandable. Don’t worry about the settings but rely on the screen to show the best pic available. Also the depth of the water has a factor that will change the view on screen.
Most of my experience is fresh water and I’m sure brackish or tidal water has its on influences.
Here’s a screen shot from this weekend that had high winds and really had the water soft and full of air(agitated). You can see the air bubbles in the pic.

Were you asking about any equipment in particular Joey? SI, DI, ML, or 360?
To me, I don't changes settings much on my side imaging or 360 when going between Lake Eufaula and the Mobile Delta. For Mega Live there is a much more significant change. I could see my lure at 60' in cleaner water at Eufaula. Last week I fished Tensaw, Raft River and the head of McReynolds and it was 30' before I could see my lure.

I was mainly talking about SI and DI. I only fish the Tensaw and Mobile River area and was just curious if others in cleaner water use more of their sensitivity range. The water I fish stays dirty year round.

“Dynamic Contrast” was added in newer units for cleaning up the screen in dirty water situations ...

Rickie I’ll turn it on Saturday and see how it works. I saw it but wasn’t sure exactly what it was for.
Thanks for the tip
