Skypup.
Are you capable and willing to help answer that question above regarding the chart I requested? I want to know how far away the science tells us we should expect to be able to see that hog in David's example when it turns broadside to us? And ultimately I would like to know what I should expect to be able to see using my Flir vue pro 640/19 mm camera? So far, I don't think I've been able to see anything beyond about five or 600 yards with it. As an alternative, Could you please show me how to complete the chart for one size and then I could make my own chart? Thanks. |

I didn't ask you anything. But since were talking, how far down on that chart can you read at your eye doctors office under control to settings? I have 20/10 corrected vision. Quote HistoryQuoted:

Try mounting your FLIR Vue up higher and keep the terrestrial portion of the camera in the bottom 20% of the lens to keep the terrestrial debris out of the gain control adjustments. Then try making your own chart with the formulas and test them out with your gear to verify what you pick up with your equipment, be sure to do this under ideal atmospheric conditions and utilizing a target object with high thermal emissivity of an approximate value of 1.0. |

Take home message for novices is that what you think you are seeing, is not what someone else thinks are are seeing.

And if your one of the 10% of males with genetically X-linked color blindness, you might want to actually look through a GENII NVO device prior to dropping the coin on it, instead of just listening to the sales pitch.
A white phosphorous tube may be more to your liking. |

They would not matter that much except for the differing color contrasts for the casual user, but still would disqualify NVO use while flying planes and choppers, as well as failing most medical aviation certifications. The difference between utilizing rods vs cones for sight may also affect other situational awareness factors like balance, depth perception, contrast, etc. that the user may find discomforting. For the casual user, white phosphor would most likely be a better choice. |

By the way white phosphor tubes are not monochromatic, the spectrum is wide and it's spikes are wider than with a single spike green phosphor.

I was speaking colloquialy... the main peak for wp is still green. And color blind folks loose one minor peak in the spectrum. I actually find it amusing how most of wp spectrum is actually not visible to the human eye since it's in the UV range. Anyone checked for increases in eye cancer from users or are they filtered? Anyhow this is way off topic. |

DwayneHicks all of the Pulsar thermal units come with a bumper-to-bumper 3-year warranty. Sellmark Corp. out of Mansfield, Texas handles all of the warranty and repairs for Pulsar products in the USA. Rest assured that Sellmark is known for taking care of their customers and I can verify they have over the years I have worked with them. The Quantum units are IPX4 rated which is basically "splash-proof" and water "resistant". They are not submersible. If you seal a Quantum unit back up in a hard case after getting it wet that can cause moisture to get inside the unit. As long as you wipe the unit down after it gets rained on and leave it in a dry place for a few hours you shouldn't have any issues with water damage. Hope that helps.
