Common Uses on a Boat:

• General Weather Awareness: Knowing the ambient air temperature is useful for planning your day, choosing clothing, and general comfort.

• Fishing: Water temperature is critical for finding certain fish species. While this measures air temperature, a quick correlation can often be made, especially when combined with a water temperature gauge.

• Aesthetics: These thermometers are often chosen for their classic, stylish look that complements the traditional appearance of many boats.

What to Look for When Buying One:

• Material Quality: Ensure it's made from 316-grade stainless steel or marine-grade brass for best corrosion resistance.

• Sealing: Look for mentions of being "waterproof" or "hermetically sealed."

• Size: Check the dimensions to make sure it fits your intended mounting location.

• Accuracy: Most are accurate enough for general marine use (±1-2 degrees).
