For measuring your pool water temperature, Poolmaster's Mallard Duck Floating Water Thermometer adds fun and pizazz to your pool, hot tub, spa or pond. The feather-molded detailing and authentic coloration help bring this little mallard to life on the water. The Mallard Duck Swimming Pool Thermometer sits on top of a 1 in. Dia tube-style thermometer body that features an alcohol-based indicator with large, easy-to-read display all housed in a 360° shatterproof lens and includes cord for tethering. The base of this cute character thermometer is lightly weighted to ensure that ducky is sitting upright in the water. Want even more fun in you pool.
