When it comes to thermal targeting, accuracy and visibility are everything. Many shooters have long relied on trusty aluminum duct tape for marking targets, but is there a better way? IR.Tools is here to explain why you might want to consider upgrading to Upright Thermal Film. It might just be worth the investment.
The Old Standby: Aluminum Duct Tape
Let’s face it: aluminum duct tape is inexpensive and generally effective. It’s been a staple in the thermal targeting community for years. But, it has limitations. The biggest issue? Its contrast varies significantly depending on your position, the target’s position, and the angle at which you’re viewing it. So, what happens when you need consistent visibility, no matter the circumstances?
Upright Thermal Film: A Step Up?
What exactly is Upright Thermal Film? It’s a specialized material covered in millions of tiny thermal mirrors, all facing in random directions. This unique design is the key to its superior performance.
So, what’s the big deal about these tiny mirrors? Because they face random directions, your target remains visible regardless of your position or the target’s orientation. That’s a huge advantage in dynamic shooting scenarios.
Seeing is Believing: A Visual Comparison


Let’s take a closer look at how Upright Thermal Film stacks up against aluminum duct tape in a real-world scenario.
In the photo above, the Upright Thermal Film sits at the bottom, surrounded by a blue ring. Above, you’ll find two targets: one made of aluminum tape and another using similar technology. In this scenario, the targets marked within the red circle are noticeably less visible than the Upright Thermal Film below. The difference is clear, right?
Now, notice those same targets moved to a different position. Suddenly, the targets in both the blue and red circles exhibit good contrast. This illustrates the core issue: aluminum duct tape’s effectiveness is heavily dependent on positioning.
The key takeaway here is that Upright Thermal Film provides consistent contrast, no matter where you’re standing. Aluminum duct tape? Not so much. Its contrast fluctuates wildly depending on various factors.
Why Upgrade to Upright Thermal Film?
So, why should you consider switching to Upright Thermal Film?
- Consistent Visibility: See your target clearly from any position.
- Orientation Doesn’t Matter: No matter how the target is oriented, it remains visible.
Is Upright Thermal FIlm worth the extra cost? If you need reliable targeting in any situation, the answer is likely yes.
While aluminum duct tape has served its purpose for many years, Upright Thermal Film offers superior and consistent visibility. Consider your specific needs and choose the targeting solution that will give you the edge.
