I've said this before but why do all these read down to 30 deg, and up to 120?, some even read down to below 0 deg, really lame in my op. A quality one that reads from 60 deg to 110 would be perfect for the pool or hot tub and the graduations would be easier to read. I guess they just take their normal thermometers and put a float around them to save money, why bother with something better if people buy their junk. I just look at the easy-touch to see the temp but I would gladly pay $30.00+ for a GOOD one to put in the skimmer. I had a couple digital floaters but they both leaked and died. I think they need some better design engineers.
