patroller formaly X1, 3 antenas, very quick, range i think was 130ft, quite quick, good box for good money. quicker than the first DSP, but there were some newer softwares so i wouldn t say better tha DSP ( much cheaper) DSP Advanced was reply to S1 and Pulse. Buy the way i do not know why BF did not switch to DSP Advanced and still use the old DSP box. ( it was first 3 antenas box). i ve got pattroler in orange color and sold it to my friend who is really satisfied.
to write more about S1, i ve got 2 boxes, the first models, very good box, really fast. what i do not like is V style and you
