External display unit for use in combination with a FLARM basic unit. Will show all FLARM equiped planes on a radar like screen. It is possible to select the plane on the screen and get more info regarding it's sink or lift (compensated) and, in combination with Flarmnet, about the plane and it's pilot.
When a plane is on a possible collision course, the unit will switch into alarm mode and will show the direction and distance of the thread.
It can even show multiple threads at the same time! (big plus i.o. V2, V3 and V4 displays).

The screen has a very good visibility in poor and full sunlight conditions.

Because of the standard 57mm instrument casing installation is a simple bolt in.

The 2nd generation display has the following extra benefits:
-a sturdy metal enclosure.
-central rotary switch for easier installation and higher torque for better use in turbulent situations.
-certifiable, DO160F ready Hardware (esp. vibration and temperature).

When installed in combination with a second display a Y-Splitter is necesary. De Butterfly can not be connected to the extention port in this case. In combination with a connection of a PDA to the Flarm we advise to use a special Y-Splitter with a switch on the dataport to prevent a conflict in the communication.
