Which LXNAV Variometer is right for you? Full S-Series Breakdown

The LXNAV S-series standalone variometer lineup is designed to provide glider pilots with a range of high-precision flight instruments, combining vertical speed indication, speed-to-fly guidance, and advanced situational awareness in a scalable platform. Engineered for VFR soaring operations, these instruments utilize high-frequency digital pressure sensors, ensuring fast and accurate response to changes in air mass and aircraft energy state. Across the lineup, pilots benefit from configurable displays, customizable audio vario feedback, and preloaded glider polar data to support efficient thermal centering and optimized cross-country performance. The S3 serves as the foundational instrument within the series, offering a compact 57 mm format with a mechanically driven needle and digital color display. It provides essential flight data including vertical speed, altitude, and speed-to-fly calculations, with a simplified single-knob interface designed to reduce cockpit workload. With integrated audio output, configurable data fields, and support for glider polar inputs, it delivers a focused and reliable standalone variometer solution suited for both primary and secondary installations. Expanding on this platform, the S8 and S80 introduce a fully digital interface with enhanced functionality and system integration. These variometers incorporate final glide calculation, thermal assistance, and the ability to display FLARM traffic when connected, along with optional GPS input for basic navigation and moving map capability. High-brightness color displays, multiple user inputs, and programmable data fields allow for flexible configuration, while CAN bus connectivity supports additional devices such as repeaters and remote controls in multi-seat gliders. The S10 builds further by integrating advanced onboard hardware, including a built-in GPS module, internal backup battery, Bluetooth connectivity, and an IGC-approved flight recorder. This enables independent operation and flight logging without reliance on external systems. Compatibility with HAWK software enhances performance analysis through real-time wind modeling and refined climb optimization, positioning the S10 as a combined variometer and flight computer solution within a single instrument. At the upper end of the standalone range, the SX Hawk focuses on high-performance variometer functionality, delivering advanced data processing and energy management through the HAWK software. This configuration is intended for pilots who already have a separate navigation system and want to add the supercharged SxHAWK to their cockpit. Across all models, the LXNAV S-series provides great variometer options for your glider. Features such as total energy compensation, customizable audio profiles, FLARM compatibility, GPS connectivity, and expandable system architecture provide flexibility for a wide range of cockpit configurations. This structured lineup allows pilots to select an instrument based on operational needs, from basic variometer functionality to fully integrated soaring instrumentation with navigation, flight recording, and advanced performance analytics.
