i dont know of any fishing forums that dont take less then a year to reply, so i thought since it wasnt sledding season, if one of you that goes bass fishing could tell me how to find the thermocline with your fish finder?? *and what will it look like?

If your interested in Ont/Michigan Forums, I can give you a large list of good forums.
However, not all fishfinders will find the thermocline. *It depends on lots of things, but you can try this.
Turn your finder to the manual mode, then turn your sensitivity up to the max. *If the screen is all black, then slowly turn it down some. *You should get to a spot, that shows sort of a line somewhere in the water column. *This is most likely the thermocline.
but again, I have had some finders that will find it, and some that won't. *It also depends on the temp difference at the thermocline. *Some are drastic, and show up fairly well, due to the density differences in the water. *Some are not to drastic, and cannot be detected.

Isn't it around 40'. I know when I took my scuba lessons you could float at that level and be in nice warm 68C and if you stuck your arm into the thermolayer the temp would drop down to about 55C or so. I don't know if it is the same depth in all lakes or not. Obviously the temps would vary.

It can be at any depth. *Infact many lakes can get two separate thermoclines.
Wind can really move them around, even blow them to shore. *Sometimes on the Great Lakes, you can be swimming in 75 deg water one day, and the right wind, can blow 50 deg water to shore. *Always shocks alot of people when they jump in.

FishHog is right to a point. You want your sonar on manual (most of the time) This can also be done with a 'ringer'. In fact a ringer is the way to go most of the time for finding the thermocline. *With a 'ringer' you just turn the sesitivity up until you get what looks like an echo. (another set of marks up from the bottom marks) That set of marks is usually the 'cline. In shallow water you have be aware of echos though. The thermocline is a line between different densities of water caused by temperature differences and that difference in density can be seen on sonar, but what you pick up most of the time is algae and other micro-organisms that prefer the warmer water and they stack up on the thermocline. Sometimes the thermocline can look up to 5 feet thick depending on the number of micro-organisms present. Many game fish will also stack up along this line. So... unless you are on a dead lake, almost any fishfinder should doo.

Yeah, I'll buy that.
Thanks for clarifying.
