I use the Moultrie 4.3 inch Picture & Video Viewer. I have been well satisfied with it. My main use is to check to make sure my trail cameras are functioning proper and set at the proper height, angle etc. I swap out my cards and random check the batteries with a digital meter. All my SD cards are then viewed on the computer. Some animals etc. may not display proper on the Viewer due to their size. This is where the computer viewing comes in. This viewer cost $140.00 plus tax Canadian. Good luck in whatever you choose.
