This TSO'd Transponder is the world's smallest and lightest of its kind, weighing in at 600 gms (21.1oz). The T2000SFL has very low power consumption and many new innovative safety features only found in much larger and expensive Transponders. The T2000SFL has attracted so much attention around the world, that we have had to build another factory to double production. JTSO Approval has been issued by the LBA for our T2000SFL mode A/C Transponder which is now on sale in Germany - Europe
