Flex Smart RV Levelling Navigator

Short Product Summary

The Flex Smart RV Levelling Navigator is a wireless sensor that pairs with a smartphone app to show your caravan or trailer's pitch and roll in real time. It suits single axle, dual axle, motorhome and fifth-wheel setups, and lets you level from the driver's seat instead of walking back and forth to check blocks.

Why This Product

Levelling a caravan by eye usually means climbing in and out to check a spirit level, or standing behind the trailer directing whoever's driving. This sensor puts the pitch and roll reading on your phone screen instead, so you can see how much ramping each wheel still needs and get it right without a spotter or repeated trips back to the hitch.

Key Features

• One-person levelling – see how far off level your rig is without anyone standing outside to guide you
• Bluetooth app control – dual-axis pitch and roll readings sent straight to your phone
• Calculated ramp height – the app works out how many centimetres or millimetres of ramping each wheel needs
• Red and green indicators – guide you to a 0-degree level without guesswork
• Internal mounting – the compact sensor body mounts inside the caravan, away from the elements
• Flexible power source – runs on its own battery, or can be wired to a 12V supply

Ideal For

• Owners who tow and set up alone who want to level the trailer without a second person outside directing them.
• Dual axle caravan and trailer owners since the sensor covers single axle, dual axle, motorhome and fifth-wheel setups.
• Weekend campers who want less setup time who'd rather read pitch and roll on a phone than shuffle blocks under each wheel by trial and error.
