|Comments||This transponder is almost a slide-in replacement for the Terra TRT-250. It uses a different rack (about one inch deeper), but the backing plate and wiring can be transferred to the TRT-250D rack. The only wiring difference is the dimmer, which is not needed with the TRT-250D's self-dimming display.
We currently have both original Terra TRT-250D Transponders as well as the newer "Terra by Trimble". The Trimble units are available at extra cost.
Terra's TRT-250D transponder takes the all solid-state design of the TRT-250, and adds a more readable display and a number of convenience features. Like the TRT-250, the TRT-250D does not use a cavity tube. As a result, reliability is improved, and no warm-up time is needed before operation. This unit is small, lightweight, and has low power drain.
Other TRT-250D features include:
