I understand Batman's interest. There's a personal satisfaction in finding it before the pro's with the right equipment do so.
Having found several first and one that PD gave up on, it's satifiying. Especially because I have no DF equipnment (like Batfreak, he's cheating). I can find 'em by "ear" using several different receivers that each exhibit a different level of sensitivity
I have a Vertex VHF that's very sensitive in the upper VHF band, a SPECTRA VHF that's that's a bit number there, an Alinco HAM rig that's downright numb at 173 (way off of center) and last but most importantly, just my BC250. The 250 being the worst receiver of the 4, will only 'hear' the blirps when you are in the same block as the target. So, by working down from the Vertex and a little moving around, i can quickly paint a picture in my head of generally where it is. Once narrowed down, it's just a matter of time until the 250 starts to chirp.
I've actually done some training with the Lojac rabbit.(training transmitter with a training code in a portable box). My record was 5 minutes.
The hits I've located were parked. I think a moving one would be much more difficult with my system.
If you chase 'em don't even consider any contact. Get a visual and split. It's just a hunk of metal and not worth getting hurt over. I'm pretty sure Batman would never make contact upon locating an occupied vehicle. I don't even bother to notify PD when I locate them. They'll find it soon enough. I just move on and smile......
