I have an X320 and I like it as a spotter.
Which is all it ever can be, because the design incorporates packaging features that render it very difficult to use otherwise.
Things I really like:
A child can learn to run it in two minutes. This is a unit you can hand off to anyone, and he will be able to use it.
The close focus range is about 2 or 3 feet. That makes the device useful for many tasks unrelated to spotting critters. This is a valuable thing.
The device runs on cheap batteries but can be loaded with lithium when desireable.
Things to plan for:
The waterproofing relies upon an O ring on the battery door, and the thumbscrew engages an insert that is molded into plastic. Get a spare door and pin and be prepared to use it.
Same for the control side cover.
If either gets damaged, stay out of the rain.
It is hard to find a dealer who can alter the standard on screen symbology. This symbology includes a worthless battery meter, an IRP logo, and maybe other stuff in the 50. They take up valuable pixels, and, in the case of the battery meter, can change and trigger offboard video processing software (seems like motion) if you try to use the device for fixed surveillance.
The LCD display is tough to see on bright days. You will dang near need a hood over your head on some days.
I kept my X320 after getting far better gear. The thing is perfect for loaning and for keeping in the car at all times.
It works.
