Measure temperature?

Hi Out There- apologies if this should attach to another thread, but I am wondering what people use to measure temperature in their preferred bodies of water. I have used suunto, timex, and alterra watches over the years and it is an ongoing challenge to find something reliable and somewhat accurate - I had have 2 aquarium-type thermometers die in the last month, by the way, so clearly I am not getting the right ones! Thoughts? Thanks!

    I have one that is used to take pool temperatures. It's housed in a sturdy case. Got it at Wal-Mart for something like $6.00. BTW, it's your basic analog thermometer.

    We use @uss_lenning's big toe around here. Those big toes are amazingly accurate. Someone's pool thermometer tried to tell me it was 51 degrees the other day. I promise it was closer to 54. I don't trust all that silly technology.

    Yea but the 51 did give me greater bragging rights

    Definitely the toemometer. Mine is accurate to within one degree. But it needs callibrating again this year.

    We use one of these floating cheapies at the pool:

    I used to have an aquarium thermometer, until I left it in the car on a warm day. The Toemometer won't explode in a hot car.

    It's always a bad hair day when you work at a pool.

    Yes you are preaching to the choir about the toemometer, but 1. I have been in a pool all winter, so need some calibration AND 2.temp is a constant debate here (amongst my co-swimmers) and sometimes you need a number to settle things (and yes I know there are bigger problems out there)!

    I have a Nixon watch that shows temperature and it appears to be fairly accurate. The only problem is that it takes about 10 minutes to fully adjust.

    I've had a few thermometers like the ones linked and have found the quality on them to be poor.

    Whatever we're using in SF right now , IT"S TOOO DARN HOT!!
    Aquatic Park has 3, ( THREE) thermometers in various places in the cove.
    On any one day, we will come up w THREE ( 3!!) different temperatures over the course of one swim of about 25 min. Since we can't change the temp, I'd go w the "toemometer'

    Looking for the next big thing.. ... @suzieswimcoach

    I use a digital waterproof thermometer, accurate to the 0.1oC. You can actually calibrate it yourself by stirring it in an "ice slurry":

    An "ice slurry"... is that secret code for "blended margarita"? :)

    That looks like the meat thermometer I use when barbecuing meat. When do you stick it in? At the start of the swim, or do you use it to decide when it's time to get out?
