Getting into thermal imaging usually means expensive, bulky gear, but that seems to be changing. YouTuber Texas Plinking recently reviewed the Infitac Fast Mini FMP13, a small, versatile thermal sight. His review looks at whether this tiny optic can actually deliver surprising results, especially considering its compact size and more accessible price point. Texas Plinking investigated if the FMP13 really makes useful thermal technology more reachable for the average person.
Texas Plinking's First Impression: Surprisingly Small with Plenty of Mounting Options
When Texas Plinking saw the Infitac Fast Mini FMP13 for the first time, they thought it was very small. He said it looks a lot like a normal red dot sight and that from some angles it's about the size of a "postage stamp." He also said it's very light, weighing only four ounces.

He also said right away that it was flexible because the thermal comes with an RMR footprint adapter plate, which is a popular way to mount things. Other adapters, such as those for the Leupold Delta Point Pro, 45-degree canted mounts, and piggyback options, made it even more flexible for different guns and user tastes, which is a theme he returns to.
The FMP13 in Action: Texas Plinking's Multi-Platform Testing
A big part of Texas Plinking's review was trying and mounting the Infitac Fast Mini FMP13 on a variety of guns to show how flexible it is.
On a Pistol
A Stealth Arms Platypus (a 2011-style pistol) with a Leupold Delta Point Pro footprint adapter was used to place the FMP13. It was then mounted on a Springfield Armory Kuna with a Picatinny rail adapter. He thought this use was very interesting, saying, "running it on a pistol because it's so small... I just haven't seen that done," and then adding, "hell yeah it's cool." While it's fun to use for fun or as a range toy, he said that for self-defense, the time it takes to set up (turn on, cover the lens for an update, and then get the reticle) makes it less useful than a regular weapon-mounted light for quickly engaging a threat.

As a Canted Optic on a Rifle
The FMP13 was also tried as a canted optic, which means it was attached to a PSA Mark12 Mod S rifle at a 45-degree angle along with a 1-10x LPVO. Its function changes to that of a quick scanning tool in this setup. A shooter can quickly switch from the main magnified optic to the thermal optic to find heat signatures or find their way when visibility is low. Texas Plinking pointed out that a simple reticle, or even none at all if it's only used for scans, could be useful for this task. "I could see this being the most popular use case for sure," he said, because it added little weight and made people more aware of their surroundings.
As a Standalone Optic
The possibility of using the FMP13 as a primary, standalone optic on a rifle or large format pistol was also explored. While its compact size makes for an exceptionally lightweight setup, particularly for activities like hog hunting, Texas Plinking acknowledged that there are "mega compromises" compared to larger, dedicated thermal scopes like AGM or DNT models, which would offer superior range and image detail for such tasks. However, he conceded that "could you get it done with one of these? I think so."
As a Handheld Pocket Scanner
Beyond firearm mounting, the FMP13's diminutive size allows it to serve effectively as a handheld thermal monocular. Texas Plinking emphasized this, stating, "just have it in your pocket and use it as a scanner that's big too without like lugging out a whole lot of equipment that's the real world use where I could actually see it as an advantage." This off-gun utility adds another layer to its versatility.
Fun Factor on a .22 Pistol
To round out the testing and showcase its recreational appeal, the FMP13 was even mounted on a Ruger Mark IV .22 pistol. This demonstrated its potential as an enjoyable accessory for range days or informal night shooting, adding a unique thermal perspective to casual plinking.

Performance Deep Dive: Image, Zeroing, and Usability
Texas Plinking detailed the FMP13's field performance, covering its user experience, zeroing process, and thermal image quality.
User Experience
Startup requires holding the power button. Texas Plinking advised covering the lens for the initial, immediate refresh. Once on, the touchscreen was straightforward: swipes controlled reticles, color palettes, and zoom. Accessing the main menu (for brightness, contrast, calibration) was also simple by holding the bottom button.
Zeroing the FMP13
Zeroing was relatively uncomplicated. After initial shots, Texas Plinking used the zeroing menu to adjust the Y-axis (elevation), aided by an on-screen original reference point. A few adjustments allowed him to hit progressively smaller targets. He concluded the process, exited by holding the bottom button, and summarized it as "pretty easy to zero."
Thermal Image Quality & Detection
The review highlighted the FMP13's ability to clearly detect heat signatures, such as steel targets against cooler backgrounds. Texas Plinking noted his truck's "warmer" brakes, a still-warm burn pile, and even a "bunny for a split second," showcasing its wildlife detection. Different color palettes (White Hot, Black Hot, multi-color) were demonstrated for optimal viewing in various conditions. The 0.5x base magnification proved useful for scanning, while the 1x digital zoom provided a closer view for identification. For instance, when shooting a Ruger Mark IV at closer targets, he found 0.5x "a little far" and switched to 1x, which "helps me out a little bit."
