What's it all about?

[bob clenton]

I''m fairly new to TVR''s and thought I might invest in a little licence preservation, but what''s it all about? I know I could read the whole forum but could somebody give a brief run down on what''s on the market to detect speed cameras, how they work, how effective are they and are they leagal. The whole jargon thing is very confusing, whats a SPECS?
