My own [External] RPM/WPM Radar is working pretty good and undetected. Shows players, vehicles, tents, current weapons and has options for changing fog distance, no-grass, night vision without having night vision, and no fatigue.
There was a thread here about making your own and it's pretty in depth.
Currently trying my hand at an Internal ESP but I think that is a bit out of my league. External Radar does the job.
