| how can you see on your depthfinder where the thermocline is (suppose it's no state of the art depthfinder, just a regular one without a thermometer)? |
|

|
| The better/more sensitive the depth finder, and the more sharply demarcated the thermocline, the more you will see it. I think you need your gain cranked up pretty good, and be on a body of water that sets up a real distinct stratification. To be honest I have never seen it show up on my electronics & lakes. |

| It will come across your depthfinder as a straight line. I see it sometimes, usually at around 20 feet deep. It is not always at the same depth in the same lake. My depthfinder is a low end portable (Humminbird Wide 100 portable) that I've been using for about 7 years now. The more I use it, the better I get at it. However, I plan on upgrading when I get a better boat & trailer, hopefully in the next year or so (my present to myself for retiring after 30 yrs. on the police dept.). |

| is this with fish-ID on or off? That gives a totaaly different view. As you can tell, I'm fairly unexperienced with depthfinders but I'm trying to learn more. |

| Divani,
Turn the fish I.D. off, if the thermocline is distinct the unit may interpret it as alot of little fish symbols. Set your gain in the manual mode and adjust gain up until you see the band on your screen. Shallow windswept lakes will be less likely to stratify than deeper more sheltered basins, also the clearer the H2O the deeper the thermocline.
later,

| Like Todd, I do not use the fish ID |

Somewhere in the archives is a thread on thermoclines and viewing them on sonars. I think from sometime last fall???
I replied in length to this, it is a subject I am very familiar with...Possible to find it for flashback Fri?
Don't remember if it was on general discussion or ask a pro. I don't have time to reply right now in that length again but will check later to see if you found it if not I'll go over it again...
One thing I'll quickly mention if your sonar is less than 2,500 watts your chances of defining the thermocline are very slim.
