The fox whistle is the ultimate low cost tool you can use for measuring depth to water. Our fox whistle is made from stainless steel, is 20mm in diameter and 200mm long. Air is pushed through the hole in the fox whistle and when it comes into contact with water, it makes a whistling sound.
A 30m tape on a windup reel is also available to order as well.
Please Note – Maximum depth recommended is approximately 20m, otherwise you may not hear the whistle. Also, not recommended for use in noisy environments such as a busy road or noisy site, as again you may not hear the whistle.
