Starting to filter through my thoughts and options on external mics for the Canon G20. Not looking to spend over $200 to be honest. Options from experience on good ones, bad ones...?
I have a like new Rode VideoMic for sale right now that would be a killer option for you. I'd cut you a really good deal on it as well. https://forums.bowhunting.com/threads/rode-videomic-like-new.88370/
I have the canon DM-100 and its in your price range new. It comes with a wind cover too. No need for external wires as it hooks up to the hotshoe on the G20. It does a great job.
