1. DIGISYSTEM Cable Avoidance Products

2. Introduction Every year site workers are injured due to inadvertently striking buried utilities such as electricity cables or gas pipelines. Obtaining accurate information about the location of buried utilities has never been more essential to protect employees and equipment during any excavation project. Local legislation normally prescribes the use of a locating device before any kind of excavation takes place. It makes perfect sense to search for, trace and mark all services before digging commences. 2

3. What is the Leica DIGISYSTEM? The Leica Digisystem allows users to detect buried utilities with ease. Digisystem has been specifically designed to reduce human error and to increase site safety with its intelligent and unique features. The Leica Digisystem comprises of: Digicat 500i/550i Service Locator Digitex 8/33 Signal Transmitter Digitrace Service Tracer Digisystem makes locating underground cables and pipes a simple and speedy task, increasing your onsite safety and ultimately saving time and money. 3

4. How does the Digisystem Locate? The Digicat 500i & 550i locate buried conductive services by receiving electromagnetic signals which radiate from them. The Digicat’s intelligent software interprets the signal data and provides the operator with an audible and visual response to the location and direction of buried utilities. The operator can mark the ground or use a GIS mapping device* to note the location, providing the excavation team with clear indications of where not to dig. *available on Bluetooth enabled Digicat models only. 4

6. DIGISYSTEM ‘i-Series’ locators 6 Digicat 500i The latest rugged cable avoidance tool. Designed to locate and trace buried conductive services which radiate electromagnetic signals. Digicat 550i Digicat 500i contains has the same functionality as the Digicat 500i, however it offers service depth estimation, when used in combination with the Digitex signal generator in 8 or 33 kHz mode.

7. DIGISYSTEM Range Digitex 8/33™ Signal Generator Improves buried service detection by applying a traceable signal to conductive services where no signal is present. (incl. batteries, connection cable set, earth spike & user manual) Digimouse Dual Frequency Signal Transmitter 38 mm diameter signal transmitter used to trace drains, sewers and other non-conductive services. Can be attached to drain rods, boring tools, inspection cameras, etc. Digitrace Service Tracer Allows tracing of plastic ducts, clay drains and other non- conductive conduits. Available in three lengths (30 m/50 m/80 m)

8. DIGISYSTEM Accessories Signal Clamp Provides a direct connection from the DIGITEX™ to metallic pipes, cables, etc. (max. 100 mm outside diameter) Digisystem Carry Bag Carries the main components of the System Digisystem (Digicat 500i and Digitex 8/33) & accessories. Constructed from rugged fabrics and complete with shoulder strap. Property Connection Set Cable Set to apply a signal from Digitex onto property power cables

9. Digisystem ‘i-Series’ Locators The new i-series locators are a technological leap forward from their predecessors; the Digicat 100 & 200.

11. The i-Series locators have been specifically designed to be easy to use with an emphasis on user safety. Automatic controls - making the Digicat easy to use, requiring minimal user experience. Starts in ‘Power Mode’ - ensuring the most potentially dangerous current carrying are detected first for maximum operator safety. Automatic Pinpointing - Highly visible digital LCD display with built-in light sensor, automatically enabling the backlight in dark conditions. Enhanced Digimouse Detection - The i-Series feature a numeric signal strength readout, specifically designed to make Sonde location simpler. In-built Test Function - allowing operators to test the hardware and software functionality of the Digicat before use. Product Overview User Benefits

12. ‘Auto Mode’ - combining the benefit of simultaneous detection in Power and Radio modes and helps to confirm the presence of services upon initial site occupation making cable detection easier and safer! ‘Hazard Zone’ - indicates the presence of a shallow buried service in power mode, (within approximately 30cm) alerting users to the increased risk. Bluetooth Data Transfer - Both i-Series locators can be purchased with the added benefit of Bluetooth wireless connectivity. It will allow the products to integrate seamlessly with mobile mapping technology to log survey data. Pinpoint Assist - maintains the highest peak reading obtained on the signal strength indicator for a period of time, allowing the operator to quickly and accurate pinpoint the service position. Product Overview Significant New Features

13. The Digicat cable locators have multiple modes of operation for maximum flexibility… Auto Mode Automatically locates power or radio signals, helping to confirm the presence of services upon initial site occupation making cable detection easier and safer! Generator Modes (8 and 33 kHz) Locates a specific signal applied by an Digitex 8/33 dual frequency signal generator to a metallic underground conductor. Radio Mode Traces signals originating from distant radio transmitters. These signals penetrate the ground and are reradiated by buried conductive cables and pipes. Power Mode Locates power signals radiated by energized cables Modes of Detection

14. The i-Series locators have been specifically designed with our distribution partners in mind… Service Due Indicator - supporting customer planned maintenance schedules or quality systems by displaying a ‘wrench icon’ after 12months use. Service Partner Details - can be programmed into the i-Series locator, so that a business name and phone number can be accessed when the locator is due for service and calibration. Pictographic Quick Guide - on the rear label, with a printed quick guide supplied with every product. Intuitive User Interface - Perfect for inexperienced users and the hire market Product Overview Dealer Benefits
