Is B and W Tongue Weight Scale Accurate Even with Lighter Weight Tongue Weights

Updated 02/26/2026 | Published 02/25/2026

Question:

Hello. I see that the digital tongue weight scale reads to a max of 4000 lbs. Do you know if the accuracy is linear across the entire range of measurement. I have a loaded trailer weight of 6800 lbs and would have a tongue weight considerably less than 4000 lbs.

Hey Gary, this is a great question but the B and W Tongue Weight Scale part # BW34KR that you referenced is totally accurate from it's max down to it's minimum so the accuracy would be considered linear. We tested it on a camper that only had around 150 lb of tongue weight and we found that it worked just fine. It would work great with your trailer that probably has a tongue weight rate around 700 lbs.
