Caldwell Boxfindr, a reader of this site explains this device: <br /><br />Another name for the boxfinder is "<a href="http://physics.kenyon.edu/EarlyApparatus/Electricity/Dip_Needle/Dip_Needle.html">dip needle</a>" since it gives an<br />indication of the angle at which the earth's magnetic field "lines of<br />force" intersect the horizontal surface, thus the instruction to align the instrument in the N-S plane. The dip angle is affected by the presence of magnetic materials used in valve boxes and/or survey marker bars. This instrument often comes as a rectangular 3x3x2 inch box suspended from a shoulder strap and having an angled mirror to allow the needle and scale to be viewed from above and may be found as part of the equipment carried by most land surveyors.<br /> <br /><img src="http://img.photobucket.com/albums/v80/harnett65/Album%205/pic813a.jpg"><br /><br />The full text on the lower face reads:<br />"Hold vertical with needle<br />in north and south line<br />move steadily near<br />surface over the<br />suspected area"<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />814. <a href="http://museums.leics.gov.uk/collections-on-line/GetObjectAction.do?objectKey=172784">Anemometer</a>, used by miner's to measure the flow or velocity of air at the entrance to a mine.<br /><img src="http://img.photobucket.com/albums/v80/harnett65/Album%205/pic814ca.jpg"><br /><br /><img src="http://img.photobucket.com/albums/v80/harnett65/Album%205/pic814m.jpg"><br /><br /><img src="http://img.photobucket.com/albums/v80/harnett65/Album%205/pic814n.jpg"><br /><br /><img src="http://img.photobucket.com/albums/v80/harnett65/Album%205/pic814b.jpg"><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />815.
