Decided to buy my first Whistler(XTR693SE).
But their are so many different setting combinations. ka norm & ka max, 3 different filter settings, filter,filter 1 and filter 2. And 3 different city modes city,c1 lo x and c2 no x.
Not sure how the different filters work in relation to each other.
Example: is ka max with filter 2= to ka norm?
What works for you hardcore Whistler users?
