| 摘要 |
A lighted survey rod of the present invention comprises an extended member having measurement indicia included thereon, a series of light emanating sources positioned along the member so that the light emanating therefrom provides a surveyor with the ability to observe and record surveying measurements in low light and/or night time surveying conditions. In a preferred embodiment, a battery source powers light emanating elements evenly spaced along the extent of a survey rod, illuminating measurement markings along such rod. Different intensities and/or colors of lights, luminescent material, etc. can be used to indicate measurements along the rod. Mirrored surfaces can be used to further enhance the visual characteristics of light emanating from the lighted surveying rod of the present invention. Still further embodiments comprise multi-sided surveying rods having a central cavity through which a lighted insert can be provided which illuminates desired portions of such rod, thereby facilitating night time and/or low light surveying operations.
