Mining Instruments

A Typical set of mining instruments housed in a box with lid.

The above items are fitted into special compartments: a mining theodolite consisting of a graduated horizontal disk with two small magnetic compasses, and a graduated circle inserted on a vertical rod and fitted with a hook-shaped index; a triangular clinometer; a protractor disk with an index; another disk fitted with a mobile quadrant at its center to compute slopes in mineshaft excavation; and two plummets.

Brought to Florence from Germany by Prince Mattias de' Medici in the first half of the seventeenth century.

A Typical mining instrument housed in a box with lid.

The following item is fitted into a special compartment: a mining theodolite consisting of a graduated horizontal & Vertical angle encoder and at its center a computer to measurer slopes, drives, angles & direction in mines. Brought to Australia from Japan by Survey dealers in the first half of the twenty first century.

Well haven't we come a long way.......

Enjoy Your Day

Theodolites

Theodolites

The extensive range and choice available these days can make it hard to pin point the right tool for the job. Theodolites are all about Angles and Lines to get you the Precision Accuracy needed on your next Project. They are the preferred tool for Serious Engineering, Builders, Construction, Drainage, Line Boring and Fencing Contractors.

Theodolites are either Optical, Digital or Laser.

The choice you make with these items depends entirely on your Budget and The Accuracy you are required to achieve. The basic optical models are cost effective and great for Fencing, Drainage, Line & Grade work.

The Digital Range have been welcomed over the years by the Likes of Engineering, Building, Line Boring and Construction Trades. They are Fast, Easy to use and Accurate. Theodolites are not Total Stations which are commonly used by Surveyors, however they can be used in conjunction with an EDM to shoot distances and Optical Eyepieces to obtain greater angles in the vertical positions or in confined spaces where there is little area to move.

Laser Theodolites are basically a digital theodolite with a long range laser targeting system.

Now that I have cleared that up??? Feel free to drop me an email with your budget and application and I can narrow your choice for you.

Enjoy your day

GPS Overview Page

GPS Definition: "Global Positioning System: A worldwide radio-navigation system that was developed by the US. Department of Defense. In addition to military purposes it is widely used in marine, terrestrial navigation and location based services."

Well that's the definition out of the way here are some resources I have pulled together to help in your search.

www.trimble.com/gps - GPS is a complex technology but understanding it can be quite easy if you take it one step at a time. This tutorial is designed to give you a good basic understanding of the principles behind GPS without loading you down with too much technical detail.
We recommend that you follow the tutorial in the order it's presented, especially the "How GPS works" section. In that section the logic of the explanation develops one step at a time.
Please Note: Macromedia Shockwave Player is required to view the tutorial.

Click Here - For those of you who do want the full technical information and terminology.

www.spectraprecision.com/epoch.shtml - About as good as it gets without having to spend a squillion dollars on a RTK system or a surveyor.

www.garmin.com - Serving both the aviation and consumer markets. There products are used in flying, boating, driving, hiking, and many other activities.

http://www.magellangps.com - Provides interactive demonstrations of there hand held GPS allowing you to become familiar with how most hand helds work without having to buy one ;-)
