What equipment is used to measure ice thickness?

An ice thickness gauge is specifically designed to measure the thickness of ice accurately and efficiently. This instrument often features a probe that can pierce the ice surface to take precise measurements. Its construction allows for quick assessments and is particularly useful in ensuring safety on ice surfaces, such as rinks or natural bodies of water.

While a measuring tape can theoretically measure ice thickness if placed correctly, it is not designed for this specific purpose and may not provide the precise readings required in many situations. A digital thermometer measures temperature rather than thickness, making it irrelevant to this question. A hockey stick, despite being a common tool on the ice, serves no function in determining ice thickness. Therefore, the ice thickness gauge is the most suitable and reliable choice for measuring ice thickness.
