Congratulations

Congratulations on the purchase of your new advanced Bullard T4MAX

Thermal Imager.
The new Bullard T4MAX combines advanced thermal imaging technology

with our expertise in high heat, impact resistant engineered polymers to

bring you the most durable thermal imager on the market. The T4MAX’s

innovative, compact design and logical, easy-to-use interface presents a truly

personalized thermal imaging tool to today’s firefighters.
The benefits of using thermal imaging technology as a firefighting tool

encompass nearly every aspect of a firefighter’s job. Thermal imaging is

better decisions. Some of the many uses for your Bullard T4MAX Thermal

Imager include:
• Search and rescue
• Scene assessment
• Locating the seat of the fire
• Determining the spread of the fire
• Locating hot spots
• Identifying potential flashover situations
• Determining ventilation points
• Determining entry and exit points
• Overhaul
• Hazmat
• Wildland firefighting
• Incident investigation
• Training
