Fitting in the tightest panel space the innovative design saves weight and space. Trig is ‘better by design’ with Mode S technology that makes you visible to commercial, military and GA traffic, as a result transiting busy airspace becomes more predictable and stress free. Trig transponders are future proof too – the growing use of ADS-B further enhances your visibility and flight safety.
Designed to be easier to use, with a clear bright display the controller even comes with a built in altitude encoder!
The TT21 is a 130 watt Class 2 transponder, ideally suited to higher performance and/or high altitude performance types.
Join other pilots who have made Trig their compact transponder of choice – you’ll be in great company.
