02Pros and cons

From the published specs, not owner reports.

For it
  • Smooth 60 Hz picture on a running animal
  • 10 h of battery, 33rd-longest of 344 here
  • ~$799, well under the ~$1,995 typical for handhelds here
Against it
  • Sensitivity (NETD) not published
  • Built-in battery, so no swapping in the field
  • Heavy at 19.8 oz, 23rd-heaviest of the 112 handhelds here
  • No rangefinder, so you judge distance by eye
  • Does not record video
  • Entry-level 160×120 sensor, with less detail than a 640
