Question:

Can you explain the accuracy? The provided description mentioned +/- 5 of full scale weight.inch Does that mean plus/minus 5 of the 2000 lb max scale weight? If so, that would equal +/- 100lb which is a significant margin when measuring only 400 lb of tongue weight on a small travel trailer. Please explain. Thank you.

Hey Marc!

The +/-5% accuracy specification refers to the scale's measurement tolerance. On a 2,000-lb capacity scale, that works out to about +/-100 lbs. at full capacity. As you pointed out, if you were measuring a much lighter tongue weight, such as around 400 lbs., a +/-100-lb tolerance would be much more significant.

That's why this type of mechanical tongue weight scale is best used as a general setup tool rather than a precision measuring instrument. It's designed to help you verify that your tongue weight is within the recommended 10-15% of your trailer's loaded weight, which is the safe operating range for most trailers.

If you're trying to dial in your tongue weight as precisely as possible—for example, after moving cargo or adjusting a weight distribution hitch—a digital tongue weight scale like the B&W Digital Tongue Weight Scale w/ LED Screen # BW34KR would provide a more precise reading. This scale provides accuracy +/-0.5%, so this is a more reliable option for you.

What trailer are you planning to use the scale with? I'd be happy to help you determine what tongue weight you should be aiming for.
