TIGRE is designed to overcome many of the limitations of Compton telescopes.
Due to the relatively low density of silicon, TIGRE is an effective pair detector in the energy range 10-100 MeV, allowing low energy pairs to propagate through several layers of the detector.
In addition, TIGRE may be able to make MeV detections of AGN of the Seyfert type, which have been seen by OSSE in hard X-rays, but to date have not been detected by COMPTEL.
