This is almost like being called on unprepared in class. So here goes.
Got a laser ticket after years of no tickets at all and want to learn more.
Long ago, I purchased a new whiz bang BEL detector when they were
a start up shop. It worked well enough for several years and just wore out.
Looked for a replacement for it. Used a Cobra that was pretty annoying and
unhelpful for a while. Looking now to learn as the revenue enhancement
focus in traffic enforcement was expensive. So, I will learn and adapt.
