Q: Should I choose the "Dry" or "Glycerine-Filled" option?
A: The standard "Dry" gauge works well for general setups with low vibration. If mounted directly on high-vibration equipment or near an engine block, we recommend the "Glycerine-Filled" option to dampen needle movement, prevent internal component wear, and ensure clear readability.
