HDR vortex

The key to success in an HDR is important to find a vortex. Actually a vortex will form where there is a grid point. What is a grid point, OK a grid point is where two grid lines cross. At that point a vortex will form.

There are two types (Hartmann & Curry)

Hartmann Grid

Discovered by Dr. Ernst Hartmann back in 1915 these geomagnetic lines run along the magnetic north - south pole. They are about five feet apart along the north - south axis and along the east - west direction eight feet apart. If you check you will see that where two grid lines cross they form a grid point vortex.


Curry Net

Another type of grid discovered by Dr. Manfred Curry that can be quite harmful with its double likes. This one does not form a magnetic vortex.

Steven Gibbs says that there is also a gravity vortex like in a famous anomaly spot known as the Oregon Vortex. This cannot be used with an HDR.
