Mopeka Pro Check Universal Bundle - 2 Pro Universal Sensors, 1 LED Display, 2 Tank Halos - Wireless Propane Gauge for Your Dual RV Tanks - Monitor Propane Levels in Your RV on The LED Display or App

Why it's worth it

This bundle pairs the same two Pro Check Universal sensors with an LED display that mounts in a dash or cabinet and shows both tanks wirelessly. If you'd rather not unlock your phone every time you wonder, buy this one instead.

Picture the camper at night with the furnace cycling. You want a number, not a phone, not an app, not a Bluetooth handshake. The LED display sits in your control panel and reads both tanks at once, so anyone in the rig can glance at it — including the people who never installed the app in the first place.

Everything good about the top pick carries over unchanged. Same patented ultrasonic sensors, same magnetic mount and Tank Halo rings, same three-to-five-year battery rating, same free app with unlimited tanks and programmable alarms. You're not trading accuracy for the display. You're just adding a second way to see the same reading.
