The 2nd, the contradiction of precision is read in magnetic declination and survey
Because the outwardness of magnetic declination, making compass sensing actually is magnetic north, rather than geographic geographical north, and higher big, the modium scale chart of precision nearly all is with the warp of geographical north as map, north arrow again all with these warps as benchmark; Because all there is magnetic declination in various places, some local drift angle can reach one, 20 degree, and this is with regard to being needed the field work of pinpoint to make troubles, and is directly perceived inadequately although some compass product can be adjusted magnetic declination, easily brings puzzlement to the user.
The 3rd, existing north arrow and map homework instrument nearly all can not directly be measured the gradient on the map.Therefore especially the topomap of different proportion chi has different contour intervals, wants to solve that directly to measure the gradient on map also be a difficult point always.
The objective of the invention is to attempt to solve above these contradictions, existing north arrow is structurally done some improvement with some simple methods; Provide a kind of and have higher survey and read precision, can adjust magnetic declination easily, again can be directly measure air line distance in different proportion chi topomap, the portable multifunctional vernier north arrow of the gradient etc. with it.
This multi-functional vernier north arrow, realize by following design proposal:
This multi-functional vernier north arrow that is made of orientation master, transparent shroud, dianegative, location snap ring, ripple shell fragment, hydraulic seal compass etc. is characterized in:
Be provided with a vernier indicator in the outer ring of orientation master, adopt cursor principle to make the north arrow survey read precision and reach more than 1 degree.

On the dianegative of this multi-functional vernier north arrow, be provided with can arbitrarily change, indicate the gradient and the map scale that principle makes by level line and measure combination ruler.
Mark 24 time-zone indicators on the multi-functional vernier north arrow dianegative back side, and the matching used geographic longitude dish of 24 time-zone indicators in the rear indicia of location snap ring.
According to the multi-functional vernier north arrow of above principle and structure fabrication, its advantage is:
1,, makes the survey of north arrow read precision and reach more than 1 °, and make its volume-diminished owing to adopt cursor principle;
2, owing to adopted adjustable magnetic drift angle structure, both make adjustment more convenient, shown magnetic declination again more intuitively;
3, reach one-object-many-purposes, can measure the usefulness in orientation, can also measure the gradient on the various topographic maps easily, can also carry out the world's 24 time zone conversion simultaneously.
