The Curry grid: what geobiologists say about it
The Curry grid is said to be a diagonal grid rising from the ground, attributed to Manfred Curry, which dowsers overlay on Hartmann’s.

The Curry grid at a glance
For its supporters, the ground carries a second, diagonal grid on top of Hartmann’s; measuring instruments have never picked up anything.
A name you run into in geobiology books, with the story of its author and what can be verified.
An author’s name and a precise diagram do not make a measurement: no device has ever detected this grid.

What Manfred Curry described
Manfred Curry, born in Munich on December 11, 1899, and died in 1953, was a doctor, inventor, sailor, and author. In 1946 he published a two-volume work, Bioklimatik, with Oldenbourg in Munich, on the effect of the atmosphere on the body. The grid that bears his name comes from a 1952 article in the journal Hippokrates.
According to the dowsers who refer to it, it forms a diagonal grid, oriented northeast/southwest and northwest/southeast, regular across the whole Earth, with lines spaced about 3.6 meters (about 12 feet) apart. These are their figures, which no measurement has confirmed.
According to Manfred Curry
- a diagonal grid, running northeast–southwest and northwest–southeast
- lines about 3.6 m apart
How geobiologists say they detect it
Practitioners say they find this grid with a pendulum, rods, or a Lecher rod, walking the room step by step. No device detects it. When these tools were tried without the dowser knowing where the target was, successes stayed at the level of chance: a pendulum moves because of micro-contractions that the hand does not notice.
What research knows
As with the Hartmann grid, no instrumental measurement and no blind test has detected this grid.
A reported belief, not an established fact: nothing here replaces a measurement or a professional’s advice.
Differences between authors
Curry is not the only name attached to this grid: the engineer Siegfried Wittmann is said to have described it first, between 1945 and 1951, and Curry’s 1952 article does not name it; people sometimes speak of Wittmann lines. Geobiologists often overlay the two grids, one straight, the other diagonal.
In 2012, a researcher from the University of Oulu in Finland and two coauthors suggested in the journal Pathophysiology that the reactions of the rods might come from standing radio waves, those of radio and television transmitters. This is a hypothesis, not proof.
The Curry grid: your questions
What is the Curry grid?
A supposed grid in the ground, oriented diagonally, attributed to Manfred Curry. According to dowsers, its lines would be spaced about 3.6 meters (12 feet) apart. It has never been recorded by an instrument: it is a belief of geobiologists, reported here with its authors.
What is the difference between Hartmann and Curry?
According to geobiologists, the Hartmann grid follows the cardinal points and the Curry grid follows the diagonals. Some overlay them, others keep one of the two. Both grids belong to the same current of thought, and to the same tool, the pendulum.
How do you detect the Curry grid?
No device detects it. Practitioners use a pendulum, rods, or a Lecher antenna, whose results, tested blind, do not go beyond chance. The real risks of a home are covered in the page devoted to measurements.
Is the Curry grid dangerous?
Nothing establishes it: no effect has been shown, and no device has detected this grid. For discomfort at home, follow the box that points to a professional; fear is not settled by a purchase.
