Out of the 4, which would you purchase and why? Obviously, I want ballistic ability within the package. I am new to this, so I don’t know what I don’t know, but would prefer not to have to purchase another one because I’m disappointed in the performance of the device, or the image sucks. Would you also need to still purchase a Kestrel to pair to work with them? Make Recommendations like you were talking to a functional idiot, because I’ve been led to believe I am. Please let me know the pros and cons of your recommendations. Thanks
