A method for improving visualization of at least a catheter in an organ of a patient, the method includes displaying a map of the organ, and at least a first visual marker overlaid on the map. A position, falling within the map, of a distal end of the catheter is received. Displayed on the map are (i) the distal end of the catheter in accordance with the received position, and (ii) instead of the first visual marker, at least a second visual marker, which increases visibility of at least one of the map and the distal end, relative to the first visual marker.
