If you are a beginning Orr a master diagnostic tech, this is all you need to do 90% of your repair diagnostics. The 4channel scope with built in presets is sipper. I've been using and teaching scope classes since the days of simutech and this is it. Not as good as a interro 4 channel scope but much better than any other automotive style scopes. Better than my pico,, my AES, and my fluke 88, full color traces and does ignition, injectors, current, frequency. Then you can talk to any truck, car tractor , but no marine or bikes diagnostics like Texa. It generates nice looking reports, a decent camera, and wireless connectivity with wifi or p p9blue tooth all for less than $6000.....
