The rods detect light of low intensity
WebbThe rods in your eyes, which are primarily responsible for night vision, take approximately 30 minutes to become fully adjusted to the darkness. It’s essential that you maintain your night vision so you can see what’s happening inside and outside your cockpit. 2. Do not use High intensity Runway lighting (HIRL).

With the added amplification, light sensitivity is far better on the phototransistors. However, it does not fair better in low-light detection than in photodiodes. Since both light sensor types share a similar working principle, do refer to the previous …
WebbThe alarms increase in intensity as the GP is moved closer to the metal-target. With a pinpointing tip plus a scraping blade with side-scan capability, the GP is very effective in easily detecting even the smallest of metallic objects.
