How can one effectively identify the hot spots that can be brought back to life by the winds and dropping humidity before they can flare up? Before they can grow into another rapid-moving fire that launches aerial assaults on new fronts?

Thermal imaging technology in the form of the Scion PTM (Personal Thermal Monocular) from FLIR is the answer to those questions.

Into The Fire

Chad Costa, a battalion chief with the Petaluma (Calif.) Fire Department was deployed for 18 days on the Walbridge Fire in Sonoma County, California, and had the opportunity to put the Scion PTM-366 Thermal Imaging Camera (TIC) through its paces.

TIC is helpful at night because you can scan a large area and pinpoint hot spots

I found that the Scion’s Hot Black color palette was most useful for checking the fire line for hot spots. When the fire is burning, you don’t need this tool. However, when the fire is out and you are searching the line for hot spots, it is extremely helpful,” said Costa. “This tool is also helpful at night because you can scan a large area and pinpoint hot spots.”

According to Costa, he was able to drive around in his truck and scan large areas of the burned-out area once without having to walk around and grid the area using personnel on foot. “Plus, in the dark, you are able to make out personnel working on the fire line,” he said. “It may not seem like a big deal, but it is, and that’s another use for the tool.”

The FLIR Scion Line of PTMs

The Scion PTM-366 is one of four models in FLIR’s line of personal thermal monoculars, along with the PTM-166 and PTM466 (The PTM-366 comes in two models offering 320 × 240 or 640 × 480 detector resolution).

Live Encrypted Video Streaming

PTM from Scion line enables secure streaming of real-time thermal video to the command center

With a PTM from the Scion line, one can have the capability to securely stream real-time thermal video to the command center via networked devices.

The Scion line also has high-performance thermal lenses (ranging from 14-36 mm) that give the option of quick, close proximity detection, and the capability for more fine-tuned, long-range surveillance when needed. And one does not lose their real-time picture on the screen while recording a video.

Versatile Lens Options

Needing reliable vision from a distance? The premium Scion lenses can detect targets up to 854 yards (780 m) away for the PTM-366 with a 25 mm lens, and 1225 yards (1120 m) away for the PTM-366 equipped with a 36 mm lens.

When combined with Scion’s manual focus ring, one can achieve a level of clarity not found in other PTMs.

Superior Thermal Detection

The PTMs in the Scion line also provide optimal performance at any time of day. Their thermal imaging can pierce complete darkness, glaring light, and lingering haze (e.g., smoke in a burned-out area of fire) to give superior awareness when operating in difficult visual conditions.

FLIR’s Boson thermal core, paired with a 60 Hz image refresh rate, gives the Scion PTM advanced image processing that provides smooth, unwavering vision in the most challenging environments.

With the Scion PTM-366, one gets all that capability, and more, in a PTM that weighs only 1 ½ pound and has an IP67-rating (for dust and water penetration). So, one knows it can stand up to the rigors of wildland firefighting. The PTM-366’s power supply can come from either six CR123A 3V Lithium Batteries providing up to 4 ½-hours of service 68° F (20°C) or a rechargeable battery pack that provides up to 10-hours of operation at 68° F (20°C).
