I have a Minnkota that I got from Basspro or Cabela's for $20. It comes with a 20 foot long wire (10 feet more than I need to get to the bottom) with the temp probe on the end. It also measures the air temp at the display and the time.

I regularly measure surface temp and temp at 3' (that's the depth at the end of my dock). A couple times last Summer I took it out in the canoe end measured the water temp at other depths, just for curiosity.
