    After opening up the thermometer, I found water in the battery chamber and the battery corroded from the water... not so submersible after all...

    They are cheap and quite accurate. The fist one is quite fancy in that you can setup the variance. So I take a thermometer that I know is accurate and calibrated properly and use it to calibrate this one. Just one tip, keep the probe as far as possible from the heater and make sure the heater is in a water flow to make sure that the heated water is distributed equally around the tank, that way you get a good reading of the overall water temp. Specifically in large tanks. Smaller ones might not make that much difference.

    I use the cheap glass thermometers from the LFS simply as a guide to get an idea and make sure the water is not below 25 and not over 30.

    @David Kusner thats the type I would probably get next, probe only in the water.
