Roughly a year after the first Argus was released, we now we have the Argus 2. What makes it any better than the original Argus? Well, the Argus 2 combined with the optional solar panel is a real game-changer. Any concerns with battery replacement are simply gone. Even without the solar panel, the rechargeable battery by itself adds life to the camera. If the charge gets a little low, then plug in a charger and you are back in business. We aren't talking about a huge hit in the wallet to add the solar panel, either. For somewhere in the $30 range, the solar panel, to me, is a must-have that puts the camera out in front of the competition.
