Available in 10" or 12" Versions

Bringing 4-color storm cell tracking to your compatible Garmin GMX200, MX20, G600, G900X or G1000, the GWX68 digital radar is a powerful weather avoidance tool.

It combines excellent range and adjustable scanning profiles with high-definition target display — for reliable, easy-to-interpret, real-time weather analysis. Available with either a 10-inch or 12-inch phased array antenna, the GWX68 fits a wide variety of aircraft radome configurations. The compact, all-in-one antenna/receiver/transmitter unit saves space and simplifies installation. Also, to keep your weather picture tracking smoothly during climbs or turns, the system offers full radar stabilization to 30 degrees of pitch and roll (when interfaced with your aircraft’s analog gyro or AHRS system.)

To focus radar scanning on the areas you want to watch, the GWX68 offers pilot-adjustable horizontal scan angles from 20 to 90 degrees. What’s more, the system also includes a vertical scanning function to help you analyze storm tops, gradients and cell buildup activity at various altitudes.

Other helpful technologies include:

  • Extended Sensitivity Time Control (or STC) logic that digitally integrates weather attenuation and distance compensation, so cells don’t suddenly appear to loom larger as they get closer.
  • Garmin’s new WATCH™ (Weather Attenuated Color Highlight) feature (G1000 installations only) identifies the “shadowing” effects of short-range cell activity — highlighting areas where radar signals are weakened, or attenuated, by intense precipitation (or large areas of lesser precipitation) and may not fully reflect the “storm behind the storm.”
Automatic Target Alert feature (G1000 installations only) that looks ahead for intense cell activity in the 80 to 320 nm range, whether you’re monitoring those range displays on screen or not.

With 6,500 watts of pure magnetron muscle, this unit has more than enough power output to penetrate serious weather. So, as a pilot, you’re equipped to make smarter decisions sooner.

The Garmin GWX68: When it comes to weather avoidance, this is the “see and avoid” system you want.
