This video explores various rangefinding methods for long-range shooting, from BDC reticles and MIL/MOA calculations to modern laser rangefinders and low-tech tools like the Range-R Card. While laser rangefinders offer the highest precision, low-tech options provide viable alternatives for less demanding scenarios. The speaker emphasizes that practical field testing is crucial for understanding the limitations and strengths of each method.
This video demonstrates how to repurpose common mouse and rat traps into effective DIY perimeter alarms for SHTF scenarios. Two distinct alarms are built: a visual alarm using a glow stick activated by a larger trap, and an audible alarm using pistol primers for a loud alert triggered by a smaller trap. Both utilize simple tripwire mechanisms and offer low-cost, high-impact security enhancements for preppers.
