Watch Estwing Hammer and Hand lens A hammer with a pick or chisel end is used for cleaning exposures, for digging, for breaking rocks, and for trimming samples. Standard geologists hammer have heads weighing 1.5 to 2 lb (0.68 to 0.9 kg) and are adequate for most geologic work. A small sledge--- for example a 2 or 3 lb head on a 14-in. handle may be needed to collect fresh  samples of especially hard rocks. While using hammer, it's far essential, 1. To put on safety goggles 2. Now not to strike heavy blows while humans are nearby three. In no way to strike one angular rock edges A cold chisel maybe used with a hammer to split rocks parallel to bedding or foliation and to free fossils or specific mineral samples from unfoliated rocks. A map holder must be large enough to carry 9*9 in. aerial photographs and should be made of masonite rather than metal( which in uncomfortable to carry) or plastic (which may break when cold). A scale , used for measuring features or laying off distances on maps and photographs, should have fine, distinct graduation marks that are equivalent to even increments at the map scale used. A protractor is used for plotting structural symbol maps and for measuring angles between structures in rocks. A camera , for, photo-geologic interpretation, is an important equipment for geological field work and should be compact and strong. All 35 mm cameras have a great depth of focus than cameras with longer focal length and this is a decided advantage in photographing irregular outcrops at closer range. Samples bags of cloth or plastic maybe obtained through most suppliers, or bags maybe of tambahanheavy paper, the variety often used as nail bags. Hydrochloric acid will be needed and should be diluted just to the strength that causes effervescence of calcite but not dolomite (except when powdered). Of the hand lenses , 10X and 14X lenses are used most widely. The depth of focus of the 14X lens, however, is only 0.8 mm, whereas that of 10X lens is 2.5 mm. Good satisfactory triplet lenses generally provide exquisite images. In testing a lens, and in all other viewing, the subsequent are essential: 1. Hold the pattern in order that the area being considered is in full light --- in sunlight, if feasible. 2. Hold the lens exactly at the distance of sharp focus, with its optical axis perpendicular to the surface being viewed three. Bring the attention to the factor in which the eyelashes are normally touching the lens (that is the best function from which the complete subject of view may be sharply and with no trouble in awareness)
