so,are there any real deal breaker type of reviews on this unit?i finally have the money saved up,but need to be sure im making the right choice between this and the pulsar.

Quoted:
NUC stands for non-uniformity compensation. Long story short, the heat emanating from the lens itself has to be "subtracted out" of the total amount of heat hitting the sensor. To do that a shutter closes for a moment so that the device can get a picture of just the lens and then compensate for it. As the lens changes temperature the units will automatically trigger a NUC correction. Because it closes a shutter the image freezes for a second. Because of that, most devices will have a manual mode where you can do it yourself so that you don't get a NUC at a critically inopportune time. -Stooxie View Quote |

Quoted: How often do you have to manually do this during a hunt? View Quote As for how often it "should" be done, the unit will determine that. Up to the user to decide when the least inopportune time is though. Stooxie's explanation is mostly accurate. NUC (Non Uniformity Correction/Compensation/Calibration) is also referred to as Flat Field Compensation/correction (FFC). The "clicking" that is heard is actually a shutter that is closing and opening. This shutter is located between the core and the lens so the shuttered NUC process (referred to as an internal FFC/NUC) cannot compensate for non-unifiormities introduced by the lens. It basically corrects for variation in pixel values, primarily due to changes in temperature across the array. Other calibration processes actually compensate for lens non-uniformities. The Trijicon/BAE scopes don't have a shutter, which is why the lens cap or some other uniform source needs to be placed in front of the lens before calibrating (referred to as an external FFC/NUC). This is both good and bad. Good in that it actually compensates for array and lens non-uniformities at the same time. Bad in that the user must manually initiate the procedure and provide the uniform source. Using a source that is not uniform may even cause the image to get worse. When performed properly though, it usually produces a better image. |

Ahhh, I stand clarified! Thank you!
Fascinating stuff! -Stooxie |

All FLIR BOSON models have Non-uniformity Correction (NUC): Factory calibrated; updated FFCs with FLIR’s Silent Shutterless NUC (SSN™).
User-Controlled Manual Non-Uniformity Correction/Flat-Field Correction (UCMNUC/FFC) - There is a mechanical shutter between the camera sensor and the lens. This shutter is used to perform a non-uniformity correction (NUC) also known as flat-field correction (FFC). During FFC, the shutter presents a uniform temperature source to each detector element in the array. While imaging the flat-field source, the camera updates the offset correction coefficients, resulting in a more uniform image after the process is complete. All models allow for user to manually trigger or interrupt scheduled UCMNUC/FFC function. Silent Shutterless NUC ™ (SSN) – In addition to user controlled manual NUC/FFC all models employ a digital supplemental non-mechanical flat-field correction that allows to extend the periods between mechanical shutter events and to further reduce image noise. SSN is always ON enhancement. |

I may not be the expert, but once again we have to point out how your copy-and-paste reflexes present us with more "not quite truths."
Sounds like you can force an FFC any time but it's it not accurate to call it "User controlled" which is what folks are asking for above. A simple firmware update would fix that in a jiffy, but it ain't here yet. -Stooxie |

No worries, it’s simply better than anything else out there and exclusive only to the 12 micron Boson cores.

Except for the Quark and Tau2 cores. 10 year old technology.
Seriously, WTF is wrong with you? -Stooxie |
|

SSN is a scene-based NUC algorithm that relies on motion to isolate fixed pattern noise (imagine looking through a screen door) and then removes it from the image. It is triggered off of the amount of motion the core sees relative to the scene. For hand-held applications like hunting, there is usually plenty of scene motion. SSN basically reduces the reliance on the mechanical shutter to make a pretty picture.

Don't know much about uploading to YouTube, but it does look like compression artifacts. You also have a bad spot next to the color palette icon. I'd contact FLIR about that. Maybe a re-calibration is in order.

The manual on the Q14 mentions it but I have never seen an auto nuc. I am playing with mine in the woods right now.
I usually need to manually nuc my Q14 (640 30hz) 3 or 4 times in the first 5 minutes then the image stabilizes. |

Quoted: The PTS233 does it automatically. It will NUC several times at start-up, but the interval should increase as the internal temp approaches thermal equilibrium. There is both a time and a temperature interval so even if internal temp doesn't change, it should NUC every 5 minutes or so. The old R-Series had a manual mode where the auto NUC could be disabled. PTS233 does not currently have this feature though. Best practice is to force a NUC (by pressing the Up and Down arrow keys simultaneously) before taking the shot. As for how often it "should" be done, the unit will determine that. Up to the user to decide when the least inopportune time is though. Stooxie's explanation is mostly accurate.

Don't know really. I've used an IRPatrol for short times, but never a MKII (don't own either). The IRP seemed to be fairly stable after the first 5 minutes or so, not needing a flat field for 15 min or more. I'm always trying to improve image quality so I tend to FFC more frequently than I probably need to. It has been my experience that over time the PTS233 falls back on the time interval for FFC rather than temp so that tends to indicate temp stability is good inside the unit. I wonder how it would compare to the Trij models if the Boson was set to External. Might have to test that out.

im on the fence between the pt233 and the rxq30..any advice on either?i will only hunt 2 weeks a yr with it,then probably just do yards op's!!!lool

It's the new kid on the block. They're both great units for the money. |

Anyone start dialing in any nice/custom enhancement settings?
Or have you just been using factory settings? |
|
Lately I've been turning gain down and contrast up. Lowering gain seems to allow a higher sharpness setting without introducing too much FP noise. The PTS233 can connect to FLIR's Boson App so you can change some settings not available in the internal menus. I've been playing around with External FFC, just to see how image quality compares with the Auto/Internal setting. Be advised, by using the Boson App you can hose your system up if you don't know what you're doing. Not sure if Armasight customer service is up to speed on the Boson App so tech support in this area may be difficult to obtain.

I think I'm going to hold out for the 640 Model. Just hope the release goes quicker and smoother than the 320. Hope I don't have to wait until mid-2018 to see it.

Just received this from FLIR.
Dear valued customer: We would like to notify you that the FLIR ThermoSight PRO PTS233 displays an image that renders at 60Hz, as opposed to the originally stated 30Hz. The recorded files from the unit still output at 30Hz. As a result, note that FLIR’s product description for this unit will change as follows: From: FLIR ThermoSight PRO PTS233 1.5-6x19 (30Hz) To: FLIR ThermoSight PRO PTS233 1.5-6x19 (60Hz) There will be no change in Part # or UPC. |

This applies to all PTS-233 released BTW. Still records (record file is 30hz). Real time display is 60hz.

You must calibrate the recoil-activated video before using it.

Nice pics QP031, obviously the pics are not doing justice how much better the real time image is. Thanks for sharing those.

I was wondering why it wasn't recording my shots.
Thanks for the tip and nice pics. |

Everyone that got one of these still happy? Torn between grabbing this or waiting for the 640 version, but given how rarely i'll be able to actually use it, the 320 is probably the better buy for me.
