DeepCore is a part of IceCube that enhances IceCube's sensitivity in the low energy range enabling the search for astrophysical transient sources, e.g., choked gamma-ray bursts (GRBs). We present sensitivities to transient timescales between 100 seconds and 1 week in an energy range from 10 to 200 GeV. A dataset that is obtained from a newly developed low energy event selection is used in our analysis. We show that the DeepCore can be reliably used to search for transients between a declination range from -30° and +30°
