The Kongsberg SSBL Positioning Transponder is rated for deep water use at 3000 meters. The medium frequency SPT 33x and MPT 33x transponders are the Subsea and Seabed elements of the Kongsberg Marine underwater positioning and navigation systems. The transponder models have 56 channels for use with the HiPAP and the HPR 400 systems. Common for all models are that they, on interrogation will reply with a single or multi pulse response.

The transponders are supplied with different transponder heads. The last digit in the model identifies the width of the pattern beam. The electronics with the software is modular for all the models. The Housing length is defined by the transponder model.
