Software, user interface, modes

Mode memoryyes
Ramping modeyes

Anduril software offers many output modes. These include different brightness levels, strobe modes, beacon modes, and more. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. The ramping mode has an advantage. It offers precise control over the light amount emitted by the flashlight. The EC01 SST40 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at, this makes it hard for them to concentrate. The EC01 SST40's SOS mode produces a specific sequence of long and short flashes.

I love bushcraft and flashlights. I find joy in mastering wilderness survival skills and exploring the realm of illuminating gadgets. Bushcraft isn't just fun, it's a learning journey. I form a strong bond with nature. It's more than a hobby, it enriches me in practical and spiritual ways.
