The Fusion Thermal Boarmaster 40E Thermal Weapon Sight features our premium WAVE12 sensor with 384x288 resolution and delivers performance way above its class; often outperforming units that cost thousands more.

Our original Boarmaster 40 set the standard for compactness, performance, simplicity, and affordability. Always striving for improvement, we are now introducing  the Boarmaster 40E, where E = Enhanced. This new variant features our WAVE12 (12-Micron) thermal sensor for a higher level of performance that’s sure to please even the most demanding operators.

Immediately you’ll notice a serious uptick in target resolution so expect to see things in an entirely different way. It also features a new higher 3X optical magnification which many believe to be the perfect balance between target resolution and field-of-view. You’re going to notice that your detection range just got a lot longer too up by a whopping 27%, now 1900 yards. However, everything else is the same as we held true to the Boarmaster build philosophy of keeping things simple and your wallet happy. Expect top-shelf performance and rock-solid durability as all our benchmark technology is there, including our Arclight Ultra HD Germanium Lens, WAVE12 Thermal Sensor, Micro Click Focus, XGEN Armored Housing, T3 – Three Button Control System, and our exclusive KISS (Keep it Simple Stupid) operator’s menu, the menu that’s so easy to operate you might never read the instructions.

Many thought the Boarmaster 40 was shear perfection and we did too. Then we remembered our calling, the single statement that defines us, “Perfecting the Vision of Heat” and suddenly great was no longer good enough. For those who demand more we offer the Boarmaster 40E, the new standard in compact thermal scopes!


T3 Control System – Your Fingers Won’t Get Lost in the Dark. The only thing cooler than the way our T3 – Three Button Control System looks is how easy it is to use. Our highly intuitive three button design with its center tower makes using your thermal scope simple and easy. Every command you need is right at your fingertips, and the Center Tower evenly splits the button control panel, so you always know where your fingers are. We thought this a particularly good thing since you’ll be using it in the dark most of the time. Besides simpler is better, and the T3, well it’s as easy as 1-2-3.

KISS (Keep It Simple Stupid) Menu – You Might Never Read the Manual. You know the phrase, Keep It Simple Stupid, and at Fusion Thermal it’s the reason we can make the industries boldest statement: Our operating menu is so easy to use you’ll likely never read the instructions. Yep, that’s right. Finally, a highly advanced electronic device that doesn’t require a PHD to use. How’d we, do it? It was simple. We don’t care about making our products usable by someone on the other side of the planet, so or menu uses words and not confusing icons. Words that are in English, with instructions that are written for Americans by Americans. Wow, the happiness you find by keeping things simple.

Micro Click Focus – Forget the Dog Collar. Getting your target into focus quickly and easily is a must, and you won’t find a better system than our Micro Click Focus. Our tall tactile focus knob is conveniently located on top of the front lens assembly so it’s easy to reach and easy to find, even in complete darkness. This is critical if you want to keep your eye in the scope and on target, and unlike the dog collar design used by most of our competitors you won’t need to perform a circus act or trash your shoulder just to focus your scope. Plus, you’ll always get your best shot as the micro click adjustments put you exactly on top of the perfect focus point every time. This feature is such a big advancement over the competitive design its often touted as this thing our customers love most about our scopes.

XGEN Alloy Housing – Plastic is for toys. Metal is for tools. It’s a fact, operational heat is the enemy of all thermal devices, and if your thermal can’t get rid of the heat it generates your image quality will suffer. Worse yet is the long-term damage this heat will cause to everything in the device. Your thermal was expensive, and you’ve got to get the heat out to keep it operating properly. This is why we never use plastic or other polymer housings. Plastics and polymers are insulators and aluminum alloys are conductors, one traps heat, and one gets rid of it. It’s that simple. Sure, plastic is ridiculously cheap but it’s a shortcut we refuse to take, and it’s something nearly all our competitors do. Our XGEN (Next Generation Alloy Body) shields your expensive investment in a clad of armor, and our high-end 6082 Structural Aluminum Alloy displaces heat 71,900% better than plastic*. This is a huge difference and reason alone why you should buy one of our products. Think about it, if our competitors are taking a shortcut on something this obvious, what else are they skimping on? It’s your money buy something of value with it.

WAVE Sensor Technology – Spend Less, Get More. Is it possible for one 384 sensor to outperform all other 384s, and even some 640s? Is it possible for one 640 sensor to clearly outperform all other 640s? The answer to these questions is yes, a resounding yes. Don’t be fooled into thinking a sensor resolution specification is the definitive guide to quality, performance and longevity. The difference in what you get from one thermal to the next can be HUGE! Our WAVE sensor technology sets the standard for the industry, and delivers performance that consistently exceeds expectations. The WAVE, Wavelength Area Variation Expansion, is a technology born from our obsession about thermal technology, and why we live by the slogan Perfecting the Vision of Heat. It’s the reason our products outperform others that cost more, sometimes thousands more. Every single pixel on a WAVE sensor is carefully optimized to increase its temperature variation uniformity and sensitivity. This results in an increasingly more precise electrical signal being sent to the display, and why you’ll discover a visual experience that you simply were not expecting.

Its true, you usually get what you pay for, but you don’t always have to pay more to get more. Fusion Thermal’s WAVE technology is an industry game changer, and our products are why people are spending a lot less to get the performance they want. Yes, it can happen, you can get more for your money, and Fusion Thermal is here to make it happen.

Arclight Ultra HD Germanium Lens – Seeing is Believing. The single most expensive and important component of a thermal optic is its germanium objective lens. If you go cheap here it doesn’t matter how good the rest of your components are, the unit will never perform to potential. Arclight Ultra HD Germanium Lenses are not cheap, but they are key to making everything else perform exceptionally well. The purity of the Arclight Lens pushes the limits of technology and perfects the task of funneling infrared rays into the thermal sensor unhindered by distortion. This infrared energy dump unleashes the full potential of our supercharged WAVE sensor. The resulting image quality is exactly as expected, perfection!
Perfecting the Vision of Heat. It’s what we do, it’s who we are.

Fusion Thermal Premium QD Mount - Fast & Secure. To anchor the Boarmaster to your rig we teamed up with defense contractor UNITY Tactical to offer what we think is the most stable and versatile thermal scope mount on the market. Our unique riser features the interface for the UNITY FAST™ Offset Mount Base. This platform gives the operator the option to easily connect a reflex red dot directly to the mount riser. Something that might prove useful if a charging swine has you on his list. To complete the package we wanted an attachment system that had a proven track record of durability and precise return to zero, so we decided on none other than ADM.
