Yay, headfirst into the water! 3 seconds later: Brrr, way too cold! Maybe it would have been better to just dip in my little toe first? This digital solar pool thermometer prevents chilly surprises. At a glance, you can read on the display whether you can dive right in or if a slow entry might feel better. The thermometer harnesses the sun's energy and measures the water temperature using eco-friendly solar power. Its light turquoise design fits perfectly into any pool and harmoniously blends into the water and bathing landscape. The attachment line is 1 meter long and keeps the thermometer in place.
