In one of my videos, I said that using a standard 10.5-inch coil, I made 80% of all significant finds, while using it only in 5% of cases. I myself can not understand such a paradox, but I will try to figure it out. This is a whole science. I&try to explain point by point. For simplicity, I will check the detection distance of 5 kopecks of the USSR on the table at home. The experiment is very controversial, but easy to understand and describe. Depth of target detection coil 15 inches and 10.5 inches. • The conditional detection depth of a 10.5 inch coil of 5 kopecks of the USSR is 35 centimeters • With a 15 inch coil, the detection depth is 38.1 cm. Increasing the coil diameter by 42% gives a 10% increase in depth (roughly). Showed data for general understanding. 1. If you...
