You'll have to do better than that, a tank with the Tamiya system will pop you from 100 feet!
I guess the Tamiya range is more like modern ranges.
A 100 ft. Wow pretty impressive. I am pretty sure I can get a 100 ft with the lens, but you would have to be extremely accurate. More focus means less spread of the IR beam.
I will be equipping my Sherman with the Tamiya system, as I thought I better have a standard to compare my other tanks to. I'll be putting your Tamiya comments to the test.
