I've updated the scanner. It will now save your last selection of checkboxes, avoiding having to re-check everything after a browser refresh.
(* with exceptions. I was following one of these ghosts which was becoming steadily stronger and more regular, then suddenly disappeared. When I rolled back a few metres, the signal came back; forward again and it disappeared. Either that's a bug, or some POI failed to spawn, or the ghost contacts don't always lead to something useful).
I was going to post a thread with screenshots, but this is sooooo much better. Well done.
Only thing arguably missing - the "finger" style ghost contacts. Initially I thought these meant nothing, but some Cmdr (sorry, don't have the name) suggested they're very distant contacts. And after following many of them I think he's right. The best way of finding something on the surface is by following those contacts until they resolve into one of the above.*
It might also be useful to add early or long distance variants of the above. For instance you show the barnacle signature, but by the time it appears that well defined in your scanner you can probably already see it yourself. If searching for "high band" contacts, I always look out for any tiny horizontal dashes in the mid-to-top of the scanner, they're often the first sign of the ghost signals resolving into a POI.

Nicely done Cmdr! <oo7>
Still no sound through the iPad (i.e. Safari). Any idea what the problem might be? (let me know if I can help test any theories).
So, I finally managed to do a bit of hacky-hack to make the audio play on mobiles!
I've so far tested on a Nexus 6, an Xperia Tablet Z and an iPhone (got knows what model.... 5...?) and they all seem to play along nicely.
Please test it and tell me if you find any issues.
