It's very slow to scan - a 'free scan' of 400-470MHz in 12.5kHz steps would take around 10 minutes to complete a cycle. But you can create individual scan lists of up to 16 frequencies that will scan in a couple of seconds.
Amongst what others have mentioned, your 400-470 MHz range is way too wide.
Without any doubt, unless it's a $30k+ special type product, the best of all commercial receivers, scanners and SDR's will take some time to cover that range.
Try narrowing down to these ranges: 72-85MHz, 159-174MHz, 403-428MHz, 466-470 MHz, 476-478MHz.
Depending on where you are, use below websites as an early warning that your normal minimal traffic could increase as events occur.
Big events like shows, rally's, NYE... when you know of something coming up, start searching and log any and all freqs.
Lock out any Transformer squiggly type sounds as they are probably encrypted or a mode you can't listen to.
If you take your device on holidays, the above and below can be used for every state and territory in OZ.
