nothing was cut off with software. this only affects certain clearvu transducers that are packaged with a unit. same court case thats been going on for 3 years. they rotated the down element 20 degrees the first time to get around the patent. that didnt hold up in court so they simply removed it from all new transducers that are packaged with a unit. this doesn't affect you at all unless your purchasing a new unit that has a clearvu transducer in the box
