A large majority of GRBs exhibit X-ray emission. In addition, a dedicated separate groupof GRB, the XRFs, exists which emission dominates in the X-ray spectral range. And thethird group of GRB related objects (yet hypothetical) are the group of off-axis observedGRBs (orphan afterglows). These facts justify the consideration of an independentexperiment for monitoring, detection and analyses of GRBs and others fast X-ray transientsin X-rays. We will present and discuss such experiment based on wide-field X-raytelescopes of Lobster Eye type. We show that the wide field and fine sensitivity ofLobster Eye X-ray All-Sky Monitor make such instruments important tools in study ofGRBs.
