I used my 10 year old Whistler 1650 cause i don't have a radar gun. My detector was set on FILTER mode with pop off. I would turn my unit off and on to emit a signal to the Pro 78.
( Next video working on is X and K same sweep )

Whistler has one of the BEST response times in the industry and is great at sniffing out little blips of radar. Look at their models -- sure they don't have V1-style legendary sensitivity in lab but in the real world they can often match performance within a second or two! Mike B has a patent for locating short-burst signals by finding suspicious areas during the routine fast sweep to then go back and look more closely at during a slow-sweep. This algorithm, I believe, is the key to Whistler's abilities to detector short bursty signals.
It is also the ONLY detector on the market with selectable filtering duration -- how long do YOU want your detector to wait before alerting you that there is a false? With Whistler's new models YOU choose between 100ms to 300ms by the FILTER setting. Many Belscort units wait in excess of 700ms in their unchangeable filter options. Could this miss a blip of IO at a distance? It sure can. It's yet another filtering vs 100% detection tradeoff that IMO a user should be able to make for themselves.
Sure right now you'd like to keep your filter duration at a high value to weed out ancient Unidens still on the road which emit erroneous police-radar-frequency pulses for those periods of time, but what if all your local cops learn how to quick-trigger radar to get under that filter? Whistler lets you reduce the filtering time and decide where to draw the trade-off line yourself
