FLIR First Mate BHM-3X+ NTSC Bi-Ocular Thermal Scope Review

The ocular is just an eyepiece and nothing else. In the surveillance and tactical field, ocular devices are extensively used to occur better performance.

In this line, Thermal Bi-oculars are trending in current days due to its heat-detecting technology.

A variety of ocular gears are used for various tactical applications, in security organizations such as the military, police, law enforcement, and recreational activities such as scouting, shooting, and hiking.

You can evidently find the difference between monoculars and binoculars by its straightforward mechanism.

Optical devices with a single objective lens and one eyepiece are classified as monoculars and vice versa binoculars with a dual objective lens and double eyepiece.

First Mate BHM-3X+ NTSC Bi-Ocular

BIOCULAR is a newly developed optical device with the mechanism and features of both devices to alleviate some of the significant shortcomings of the monocular and binoculars.

Wait, I’ll lucidly explain. It has a single objective lens such as a monocular and two eyelids like a binocular.

Now we are going to analyze the features and performance of First Mate BHM-3X+ NTSC Waterproof Bi-Ocular Thermal Scope which is engineered by the FLIR manufacturer.

Let’s dive into the detailed review.

Thermal Detector

Thermal bi-oculars with thermal imaging technology have been used by more users than ordinary bi-oculars.

The device can clearly provide quality vision even if there is no ambient light. One fine thermal detector is the core technology of any ocular devices.

Like most thermal imaging devices, First Mate BHM-3X+ is configured with the uncooled microbolometer type detector to drastically increase the operation of the device in any temperature conditions.

And another benefit of this uncooled detector is that you can precisely capture fast-moving targets.

Objective Lens System

The lens system is a clever move by the designer to solve the size problem in binoculars and the price problem of monoculars.

To be more clear, using only one objective lens allows the user to see the quality of the scene with the help of two eyelids.

FLIR is the only company that started to use a Germanium lens with coating in the optical devices.

After the development of technologies nowadays approximately 90% of optical devices are configured with a coated Germanium lens.

Field of View

When you use the device in 35mm focal length then you receive 13°x10° of Field of View.

If you use the bi-ocular in 65mm focal length then it provides 7°x5° of Field of View. And the device grants 5°x3° Field of View while you’re utilizing 100mm focal length.

It has a fixed e-zoom feature to view the target closer, meaning it’s configured with 2X zooming capability.

Range of Detection

We know that the FLIR Bi-ocular System working in three different focal lengths. So each length has a different detection range.

First of all, I wish to clarify one thing, First-Mate II Bi-Ocular detects both humans and objects such as wildlife, ships, vessels, and so on.

FLIR First Mate BHM-6XR+ NTSC Bi-Ocular

Thus it has two sets of ranges of detection for humans and other objects.

Here is the first set of detection range for humans, with 35mm focal length you can detect target up to 2,550ft, and 65mm focal length gives you 4,200ft of detection range, thirdly you can get the 1M detection range when using 100mm focal length.

Now we come to the second set of detection range for other objects like a ship.

The highest detection range of 2.7M will be provided when you utilize 100mm focal length, and by using 35mm focal length you can view the target up to 1.1M, at last, you can catch the target even at 2M with the help of 65mm focal length.

Attachments

The device comes with 3 different sizes depending on the focal length.

The 35 mm has comes with the size of 10.5″ x 6.5″ x 2.6″, the 65mm is equipped with 11.5″ x 6.5″ x 2.6″, and the 100mm configured with the size of 13.0″ x 6.5″ x 2.6″.

Moreover, to provide vivid images with high the FLIR Bi-ocular system consists of three thermal imaging color palettes as White Hot, Black Hot, and InstAlert.

You need to use 4 AA Batteries in this device that has the ability to provide ample power to more than 5 hours of continuous operation.

The outer body of the device is equipped with the IPX67 waterproof aspects to protect the bi-ocular from corrosion and rust caused by bad weather/water.

With the aid of RCA jack, you can download or transfer the videos you recorded in NTSC or PAL formats.

Conclusion

The FLIR-designed heat-seeking maritime camera provides all the features you need to keep track of whether your home or ship is safe.

So you can strongly believe your purchase of FLIR First Mate BHM-3X+ NTSC Waterproof Bi-Ocular Thermal Scope will definitely provide great performance in all manner.

I hope this review revealed the complete detail about the product and it should lead you to choose the right one.
