Vexilars have do way to distinguish temp or oxygen levels. So they must be yanking your chain, or they are deducing this from where they are seeing the fish.

You can occasionally mark the thermocline on your electronics. But thermoclines develop in the summer, they don't exist in the winter, so I don't think there's anyone marking them while they're out there ice fishing.
One theory on being able to mark the thermocline is the cooler denser water below the thermocline is enough denser to reflect part of the signal (ie. mark it on the display), another theory is that particles and bugs collect along the thermocline and what you're really marking is that stuff.

Yep. definitely yanking your chain. The water temp is about 39F from a little below the ice all the way to the bottom, unless there is some sort of groundwater input. It's actually about 32-33 right under the ice, progressing to maybe 39 on the way down.
