We have taken delivery of the shielded cases which we're putting on the site for sale shortly. The price will be £9.99 for the case, screws, and buttons.
We've not tested the new shielded cases ourselves yet but we gave one to a customer that was having interference issues and the results look good so far, with very little interference. The cases don't actually look any different and there are no signs that there's any shielding in the plastic. All new Mobius cameras come with these cases as standard now.
