I’ve never heard of any approx. Footage… I’ve also never used a laser other then in a classroom for 5sec. When the trigger is pulled it gives you speed and distance from what I remember… I’m sure it gives more info and has more features… I just don’t know them.
As far as radar… I wait till someone is pretty much on top of me before I give a ticket… I really don’t do radar to often…I would rather just write a Bullshit ticket that will he dropped or reduced…
