Advanced Radar Technology Reveals Where Fish Are Biting
Furuno’s Bird Mode on traditional X-Class and NXT Solid-State Doppler Radars gives you the inside scoop on where the fish are biting. Designed to reveal shallow marine life by detecting birds gathering near fish at the surface, Bird Mode automatically adjusts the Radar’s gain and sea clutter suppression to render bird echoes with optimal visibility, helping you spot promising fishing hot spots.
What Bird Mode Is
Bird Mode fine-tunes your Radar’s sensitivity by adjusting gain and sea state filters automatically for small, repeating targets, making them stand out without cluttering the screen and helping you spot birds effortlessly from up to 4–6 nautical miles away. Bird Mode is available in MFDs (Multi Function Displays) like NavNet TZtouch3 and NavNet TZtouchXL, and is also available on Furuno’s standalone modes like the FR10 and FR12.
How Bird Mode Works
The Radar optimizes gain and sea filters automatically when Bird Mode is engaged, simplifying detection by highlighting bird echoes. Built on Furuno’s mastery of Radar, Bird Mode works alongside features like RezBoost™ for beam sharpening, Target Analyzer™ for color-coded echoes, Fast Target Tracking™, and Auto Target Acquire. While these are navigation-oriented features, they complement Furuno’s bird detection capabilities perfectly, providing a comprehensive suite of tools for any angler.
Furuno’s legacy with bird detection goes back decades, with anglers tracking fish-hunting flocks on their Radars through manual adjustments and plenty of trial-and-error. Bird Mode brings this advanced trick of the trade to recreational X-band Radars everywhere, empowering any angler with instant, automatic tuning for bird detection.

Using Bird Mode: The Basics
Here’s how to get going with Bird Mode:
Enable Bird Mode
On NavNet TZtouch, Edge swipe up to show the Layers menu, then tap Bird Mode.
Turn On Echo Trails
Turning on Echo Trails makes it even easier to distinguish bird targets from stationary vessels in the distance.
Let It Tune
Bird Mode instantly sets gain and sea filter – no manual tweaking required.
Scan the Screen
Flocks of birds often mark active fish feeding zones. Look for distinct, repeating targets (bird echoes). On calm days or with close birds, they may display as small speckles or distinct echo trails.
Toggle Off When Done
For normal navigation without bird-highlighting tuning, turn off Bird Mode.
