myfs_91650 Posted May 5, 2015 Share Posted May 5, 2015 We are building a new home and since the walls and roof are up, I wanted to take a reading from the front door. My dilemma is that standing inside the front door, I get a reading of 154 South, taking one step out of the front door, onto the outside landing, I get a reading of 132 SE. The actual door is not in yet and no tiles have been placed on the outside steps - would adding these really make a difference to the reading? I would think the front door is still in the same place, so why am I getting such a large difference in readings? Link to post Share on other sites More sharing options...
Staff Cecil Lee Posted May 6, 2015 Staff Share Posted May 6, 2015 These are some considerations:- Part 1: Hopefully, the home has a properly drawn architect/draftman's plan. If so, there should be a North marking on it. Most of the time, this North marking is accurate. However, in some instances, it may not be accurate.

Staff Cecil Lee Posted May 6, 2015 Staff Share Posted May 6, 2015 Part II: Yes, it is very common when using an ordinary compass to get mixed compass readings. Often, this is due to things like re-enforced steel rebar embedded into the concrete structure i.e. flooring or walls etc... In modern times; if one can get hold of a printed streetdirectory or an electronic one (as shown in the sample) One will notice that all street directories have the North 0/360 degrees on the top of the page. Even google maps have this geographical north marking in this format. At the equator; the geographical north and magnetic north is very close and are nearly identical. In Canada, the geographical north and magnetic north varies a few degrees. But, this is better than having wide fluctuations in compass readings. A professional compass like the Suunto brand makes compass for different regions. For example: countries in the equator; they sell one for "region 3" that is for Singapore, Malaysia, Thailand and all countries at the equator. For Canada, should be region 1 and most parts of USA is also within region or zone 1. Anyway, I don't think you do have or would need such a compass if one needs it for just one instance. Thus, you should try to use the streetdirectory or if googlemap captures the outline of your home's building, print it and use a protractor to get the compass direction.

myfs_91650 Posted May 6, 2015 Share Posted May 6, 2015 Thank you Cecil, we purchased an old home and demolished it & rebuilt, therefore, google shows the old home not the one we just built.....I suppose I can wait until more of the house is finished but I wanted to get a proper reading to help me choose colors and even materials of the finishings depending on the stars....

Staff Cecil Lee Posted May 6, 2015 Staff Share Posted May 6, 2015 Yes, if google map does show the outline of your new home; you can use the method I mentioned earlier via a protractor to determine the correct facing direction of a home.Even if one is standing on an empty land try to take a few readings as sometimes there may be metal objects embedded in the hidden ground. Things like a manhole cover can give off false reading. Or a concrete path which often has a metal mesh to strengthen it. Anything with metal is detrimental to the compass reading.Alternatively, as mentioned previously; you couldseek help from the architectural firm to provide you with the blueprint of your home. Mostof such blueprint should actually have a North marking on it. Or the sales brochure listing the entire estate may also have such a marking.

Staff Cecil Lee Posted July 30, 2018 Staff Share Posted July 30, 2018 Standing on these road tiles also no guarantee of correct compass readings. As often below the sand, there are also reinforced metal rods. And in this case taking a reading above a manhole cover or even a few feet away also may yield mixed compass readings. The workmen managed to cover the spot in an hour or so.... Link to post Share on other sites More sharing options...
