Re: Cobalt 2005 220 depth finder
You must not have clicked on the thread I linked. Your answer is there. But being an old thread, "Mike 250" may not get your message. You will need to send him a PM. The last time he posted on iBoats was July of 2010. In case it's still unclear, here is the part of the linked thread that has what you are looking for.
My guess is you have the same depth finder I have on my 2005 250. Pushing down on the toggle moves through the menu options. Once you get to the setting you want to change you toggle the switch up to change set-points.
You probably know this much already but as you toggle down through the menu you'll see something like "Un". Once you see this stop and wait a few seconds and it will show the actual depth.
I have the manual at home if you need details. Let me know.
As I also said, you can call customer service at Cobalt, or your dealer, that is what your manual recommends.
