We provide on-site training in and demonstrations of the following Carlson Mining product line, which has been developed in over 35 years of fieldwork and widely adopted in the global mining industry for reliability and ease of use.
Blasthole Survey Systems
As drilling and blasting clients know, no borehole is perfect. Boreholes frequently deviate from the intended path and cause problems and cost overruns. Factors contributing to borehole deviation can include the level of driller experience, equipment quality, drill angle, and local geology. Before the Carlson Boretrak (Boretrak) innovation, no highly accurate or easy way to measure deviation existed. Manual and mechanical methods lacked accuracy and produced too little data to be mapped against the drilling plan for comparison. Revealing the precise path of the borehole, RESPEC uses both rodded and cabled variations of the Boretrak system to help mining clients make accurate assessments regarding ore volume.
Even with today’s precision-mining advances, mine and quarry managers may make the mistake of proceeding to blast on the basis of the drilling plan instead of using actual drilling results. If engineering and geotechnical works proceed on the assumption that holes are straight, they typically encounter costly project delays later.
To reduce deviation, error, and costly mistakes, RESPEC uses rodded and cabled Boretrak deviation measurement systems to complete a wide range of drilling-related projects quickly and efficiently. Our professional field team captures highly accurate 3D measurement data needed to make sound on-site decisions quickly and safely. Reliable data from Boretrak also reduce costs for mining clients because employing surveyors or other costly personnel is unnecessary.
The Boretrak borehole-deviation measurement system is a simple-to-use, portable system to measure the deviation of boreholes. Carlson features rodded and cabled versions of the Boretrak system. Rodded Boretrak is the primary workhorse for uphole and downhole operations in areas that are affected by magnetic interference, and the handheld, cabled Boretrak is only used for downhole operations but can cover large areas that are not affected by magnetic interference. Both systems can be carried by one operator. Cabled Boretrak comes in a single PELI TM case that weighs less than 5 kilograms (kg) in total.
Both Boretrak products provide an easy way to audit drilling activity accurately and can be used in multiple applications, including quarry and cast blasting, exploration and foundation drilling, dam pinning, construction, piling, and engineering works. Boretrak confirms the actual path of the borehole after drilling. Sites that use preblast borehole-surveying tools report improved site safety, increased productivity, and lower operating costs. Boretrak provides accurate 3D survey data on boreholes and drilling activity and calculates borehole deviation. Boretrak sensors are accurate to ±0.1 degree for reliable data.
Boretrak systems are designed to work reliably in extreme environments. A high degree of dust- and waterproofing is engineered into both the rodded and cabled Boretrak. Boretrak performs reliably and accurately in extreme conditions with wet weather, water-logged ground, submersion, temperature extremes, and sand and dust. For both systems, Boretrak Viewer Software makes quarry operations more efficient by using data from portable and robust laser-scanning systems. The feature-packed Boretrak mobile application makes drilling and blasting safer, faster, and more profitable than ever before.
MORE ABOUT BORETRAK
Mine and quarry owners need a fast, reliable way of measuring borehole deviation to obtain actual drilling data that saves money on breakage, transport, explosives, and fuel costs. Boretrak can alleviate costly delays on engineering or geotechnical projects and enhance the safety of employees and those living near blast sites. Boretrak can be deployed from ground level or underground sites to safely obtain 3D data that describe drilling activity.
Boretrak works with Carlson’s Quarryman Pro to ensure compliance with quarrying legislation that protects local residents, employees, and property. Measuring borehole deviation mitigates the risks associated with incorrect borehole data, such as fly-rock caused by poorly designed blasts or intersection with underground utilities in engineering works.
By ensuring accurate data for better decision-making on the site, Boretrak’s handheld Control Display Unit interfaces with dedicated PC software and enables users to audit drilled holes and produce reports in minutes. The results can be issued to on-site drillers on an as-needed basis. Improved on-site drilling operations become data led, responsive, and better integrated with Boretrak.
RESPEC uses Boretrak to map entire sites. Boretrak data can easily be georeferenced and related to a local coordinate system. Clients can compare today’s results with historical data and view data from a range of systems—notably Carlson’s Quarryman Pro. Using these precision-mining tools, RESPEC removes guesswork and data gaps.
The dust- and waterproof Boretrak system is rugged and designed for extreme conditions. The portable, lightweight systems, which are designed for use by a single operator, are easy to transport across sites and between locations and easy to deploy. Because boreholes frequently deviate, RESPEC uses Boretrak to increase the success and safety of a blast and minimize risk to the client’s blast plan. Systems are available with wireless control and connectivity to support drilling, blasting, and geotechnical operations where safety, productivity, and profitability are key.
Clients use Carlson Boretrak® systems to:
- Avoid borehole deviation, risks, and associated costs.

Carlson’s Boretrak2 was developed as a successor to the well-known Rodded and Cabled Boretrak systems which have had a 35-year product history. The Boretrak2 has 360 degree capabilities and is used to survey drilling activity in any direction for surface and underground mining operations. The Carlson Boretrak2 is a cost-effective, rugged borehole-deviation surveying system that is compact, lightweight, and portable. The unique retractable design of the Boretrak2 further enhances the reliable and versatile probe system that offers significant advantages over previous deployment options. RESPEC uses the Boretrak2 system to confirm the actual path of the borehole after drilling. Boretrak sensors are accurate to ±0.1 degree for reliable data. The Boretrak2 assists to calculate precise burdens and supports safer blasting with fewer fly-rock incidents; reduces secondary breakage; improves crusher throughput; and minimizes environmental impacts, including airblast, noise, and vibrations.
The unit can be quickly deployed by a single operator using a variety of methods. For downhole deployment, the Boretrak2 can be lowered using a wireline. Uphole and horizontal deployments can be completed using a semi-rigid pushrod system, spooled out from a cable reel. The probe is deployed into a hole at fixed intervals. At each stop, a measurement is recorded in Carlson Scan.
Carlson Scan is the free operating software that runs on an Android device or Windows-powered tablet. It is used to set up projects and design holes, import hole coordinates, and import third-party data to form a background to newly collected data. Carlson Scan is connected to the Boretrak2 by a Bluetooth connection from the operating device which allows for setup and calibration of the unit.
Data recorded by the Boretrak2 is displayed in real-time in an optional 3D graphical mode, 2D schematic mode, or in tabular formats. Reports can be quickly generated, in-the-field, featuring data on each hole with tabular data outlining each reading during deployment. Data can be transferred onto a desktop or laptop version of Carlson Scan for further analysis. Survey data from the Boretrak2 can be exported to other Carlson software packages like Carlson BlastOPS using the DRL format or exported as a DXF or CSV to be used with other third-party CAD and blast design software.
“The Carlson Boretrak2 is the next generation of borehole deviation technology,” says Brad Husack, B.Sc., Support and Special Projects Engineer, Carlson Software. “It is the culmination of over 35 plus years of bore tracking manufacturing and field experience. With the new ability to deploy in every direction and the new intuitive and easy-to-use Android/Windows-based software, Carlson Scan, surface and subsurface operations will benefit greatly.”
The Boretrak2 probe is made of stainless steel and has a waterproof rating of IP68, allowing it to be deployed in extreme and rugged environments. Its 40mm diameter makes it deployable even in small boreholes. Operating temperatures range from -10°C to +60°C.

RESPEC offers various blast monitoring equipment for sale and service work through our partnership with ShotTrack, an Australian instrumentation manufacturing company. RESPEC provides local support for ShotTrack in North America, including Canada, the United States, and Mexico. Some of the equipment that RESPEC offers through ShotTrack is listed below.
ShotTrack VoD 305 Monitor
The ShotTrack VoD 305 is part of the next generation of Velocity of Detonation (VoD) monitors. This instrument takes the guesswork out of blasting performance issues and gives the user insight into what is really happening when explosive products detonate. Why is measuring the VoD important? The VoD can evaluate the performance of the bulk explosives being used in addition to evaluating the blast as a whole. The measured VoD can also be compared to the VoD specified in manufacturing for post-blast evaluation. Post-blast evaluation of a blast design is carried out with the assumption that the explosives have performed as per the specifications, which may not always be the case. VoD allows for measuring the actual performance in the field compared to the manufacturing specifications of the explosive product.
The ShotTrack VoD 305 monitor collects data via a time-domain reflectometer (TDR) system. The TDR system runs pulses down a standard coaxial cable and back to the unit, measuring the amount of time for a pulse to return to the system and allowing for direct measurement of the VoD. The ShotTrack VoD is calibrated to the coaxial cable being used and does not require annual calibration for the monitoring unit. The system can also measure multiple holes on a VoD trace. The results of the trace will show the consistency of the explosive mixture over the entire hole and identify any areas of problematic explosive product. Overall, the monitor gives an accurate picture of how the explosives and detonator systems are performing.
The ShotTrack VoD 305 features a sample rate of under 4uS and a nominal resolution of 90 picoseconds. Housed in a compact, IP67-rated case, the single-button operation, GPS-synchronized timestamp, and long-range Bluetooth technology put the VoD 305 in a class of its own.
ShotTrack ViB Monitor
The ShotTrack Vibration (ViB) monitor uses accelerometer technology and high sample rates for capturing key data, such as precise detonation timing. The ViB can be mounted on any axis, which makes the monitor perfect for underground and structural monitoring at mining and construction projects. The ViB systems are fully self-contained vibration monitors designed for far-field, high-sensitivity, low-level vibration applications. The ViB is offered at various monitoring limits that range from 2g to 200g, selectable sample rates of up to 32,000 seconds per second (s/s), GPS pulse-per-second embedded time stamping, and up to 1,000-meter remote wireless control and download. This ViB unit covers many low-level vibration monitoring requirements and analysis.
Position and timing are determined using a GPS receiver. Providing that a GPS fix is obtained, the triggered events are time-stamped to a Universal Time Coordinated (UTC) time and date, and a 1-second marker (accurate to +/-50 nanoseconds [ns] RMS) is recorded along with the vibration information. This embedded time signal is displayed on output graphs and reports.
In 2022, ShotTrack will release the ShotTrack Seismic & Sound (SAS) accelerometer-based seismograph with a microphone input. ShotTrack will also be offering the ViB Nano, which will use advanced accelerometer technology with a dedicated mobile phone app for control and upload in a compact and affordable form, in 2022.
ShotTrack will offer the Blast Inspection Camera (BIC), a tough, easy-to-use, high-speed camera that records 1,000 frames per second, in 2022. The BIC will also have remote upload and control capabilities.
