now your just being babbling..... I am sorry you are so misled.
But I am not arguing with you anymore, you are incorrect in your statements.
Just because videos are posted by a MFG doesnt mean they were taken by the MFG. Obviously they are all different terrains, vehicles etc. Cherry pick videos....Hmmm seems all of K40 display great range. Yes V1 hold patient on front and rear in single housing, K40 holds patient on front and rear separate receivers ie why nobody else BUT k40 sell it except the V1 but that is a different design of which he holds the patient to hense why no other portable radar offers dual horns under a single housing. Show me a independent test from a established company that DOESNT SELL RADAR.
Like I said I am sorry you are misled.
