At ToySplash we want to help you spend more time playing in your pool and less time maintaining it. That's why we're excited to offer the AccuWeigh Chemical Scoop. This scoop weighs dry chemicals so you know just how much you're adding to the water. More accurate measurements means less time tinkering with your chemicals and more time enjoying water fun. And water fun is what it's all about at ToySplash! The AccuWeigh measures ounces and grams up to 17 ounces. It features on/off and reset buttons with an easy-to-read display. Requires one (1) CR2032 battery (included).
