TILO-Challenge (4): The TILO with specialized forces

The group of testers consisted of Army Special Forces soldiers with advanced basic skills who use various optical and optronic devices in multiple spectrums in both normal operations and missions. These reconnaissance and observation devices are used in harsh conditions, which is why there was great anticipation for the TILO3Z+ from Andres Industries. The testing period lasted from August 15 to October 17, during which the device was thoroughly tested in every aspect.

Upon unpacking the package from Andres Industries, the waterproof, shock-absorbing Pelicase-like case with pressure relief valve came as a pleasant surprise, giving a highly professional and high-quality impression.

As expected, the transport container was equipped with pre-perforated foam inserts, allowing customization according to personal preferences.

The included accessories for the test were more than generous and consisted of:

• Head mount
• Helm mount
• Eye cup
• Shutter eye cup
• Battery compartment extension
• External power supply + cable
• Mini video recorder + cable
• Tripod adapter
• Camera adapter 30mm
• Camera adapter 40mm
• Battery (Type 16650) + charger
• Optics cleaning cloth
• Manual
• 3 x Cr123A battery

What stood out was the high-quality craftsmanship and the fact that each accessory was provided with the appropriate Allen and Torx keys. The impression given by the accessories seamlessly transferred to the core of the package, the TILO3Z+.

Surprised and intrigued by the dimensions and weight of the WBG (Wearable Goggle System), one wondered if the device was robust and powerful enough for the rough demands of military life. The initial critical evaluation of the basic unit revealed that the small device, measuring Length: 50mm, Width: 64mm, Height: 67mm, weighing 100 grams, was indeed very sturdy. After a rudimentary familiarization with the very thorough user manual provided in paper form and also downloadable as a PDF, it was time to insert the battery and start.

It should be noted that the TILO can be operated with either one CR123A, two CR123A, a 16650 battery, or an external power pack. The operating times in thermal imaging mode are as follows:

• Approximately 3.25 hours with one CR123A
• Over 7 hours with two CR123A
• About 7 hours with the 16650 battery
• Up to 8 hours with an external battery pack (at 20°C)

The built-in LEDs in white, red, and infrared are adjustable in brightness and can be used in three modes: constant on, blinking, and SOS. An interesting feature is that all three LEDs can be individually deactivated in the device's menu to prevent unintentional activation and avoid revealing one's position to the enemy. This is a very practical feature for tactical end users or hunters.

Once the LEDs were turned off, it was time to explore the heart of the TILO, the thermal imaging mode. In the 3Z+ model, this is made possible by a microbolometer with a sensor resolution of 320x256 pixels, 60Hz, and a temperature resolution of less than 40mK. The image is displayed on a screen with 873x500 pixels.

What may sound like theoretical jargon on paper is easily noticeable in practice and can be better explained with the following model comparison.

Unlike the newer TILO3Z+, the TILO3Z has a microbolometer with a 9Hz frame rate, which causes the displayed image to appear very choppy and "stuttering". The 60Hz of the TILO3Z+ display the image almost in real-time, making it possible to navigate in complete darkness and smoothly recognize all movements in an observation field.

The difference in temperature resolution, which is less than 60mK for the TILO3Z and less than 40mK for the TILO3Z+, means that the smaller the value, the finer temperature differences can be detected.

Having mentioned that the 60Hz TILO enables movement in complete darkness, this was put to the test. The tactical filters of the WBG, such as Red Hot, Cold Red, and Cold Green, were mainly used during this test. All unused filters, like the LEDs, can be deactivated in the corresponding submenu to make operation more intuitive.

When the device is kept in its factory settings, it can be turned on by opening the protective cover, which springs open after being pulled out, making the uncooled device ready for use in one to two seconds. Turning the device off is simply done by closing the protective cover, which securely latches shut.

After a short period of adjustment, moving with the TILO was very easy. In contrast to a residual light intensifier, stealthy shooters could be detected very well during both day and night. These individuals would not have been noticed otherwise, even at distances of over 400 meters. This improvement in identifying sources of danger significantly enhances the survival chances of tactical end users. It is recommended, however, to use the TILO simultaneously with a monocular residual light intensifier to maintain situational awareness in the multispectral range.
