RideRecon Icons - Work in Progress

Working on the icons for RideRecon. The stopwatch's outer ring was originally the same width (3px) as the radar's outer ring, but it looked odd, so beefed it up a bit. Might still tweak the stopwatch one but the rest I'm happy with.

I'd be interested in seeing what you think each icon does...

Edit: The attachment includes a small fix to some errant pixels on the 'settings' icon.

Edit 2: Some further ideas on the 'settings' icon.
