I retired after 25 years at Rockwell Automation, having delivered significant digital transformation projects to the mining industry. We delivered “the Digital Mine solutions” utilizing traditional fiber solutions. Michael Gribbons reached out to me to see if I would be interested in a sales manager role at Synergy Control Corporation, and during our meeting he demonstrated the Maestro Digital Mine Demo.

What excited me most was the in-house Engineering, R&D, assembly, and the Maestro support team! They continuously listen to their customers to expand their offering.

The Plexus PowerNet, provides a ruggedized infrastructure that is easily maintained and extended underground by the traditional E&I resources, providing the much-needed end to end system integration. I believe that this is a cost- effective ruggedized solution for all ethernet communication needs, converting from Fiber at the shaft to the rugged Plexus PowerNet in the drifts.

Coupled with the air quality stations that accurately monitor real time environmental conditions and report back to surface via digital ethernet, this provides a cost- effective solution reducing time getting back to the face.

Starting in a new sales role at Synergy Controls this past year, COVID-19 has been a real challenge to work with our suppliers to get product training. Maestro quickly adapted and introduced online training sessions as well as hands on training.

If you get a chance, you must visit their facility and see their entire dynamic team. Engineering, production, R&D are all done in house. Maestro is constantly developing new and innovating ways to improve their product lines based on the needs of the customer.

Listen, Learn & Act is one of their core values, which is an excellent representation of their company which has allowed them to bring out high grade products that improve safety and production for the industry.

Canadian technology company Maestro Digital Mine’s global advantage – monitoring multiple gas concentrations, airflow, temperature, humidity and atmospheric pressure utilizing a straightforward digital IP Connection.

The compact Vigilante AQS and Zephyr AQS – air quality stations are designed specifically for applications in demanding mine environments. Exact real-time data measurements eliminate the requirement of manual ventilation measurements and high maintenance constrictions.

Durable devises withstand mechanical vibration, turbulent airflow, high air velocity and electrical noise generated by VFD’s (Variable Frequency Drives).

My work experience with Maestro Digital Mine and its underground mining communications products started with a series of fortunate events. My partner, Mr. Guillermo Pinto, invited me to participate in a new project representing a company from Canada, dedicated to the manufacture of communication products. We visited MDM headquarters for an in-depth distributor training session. That experience was of the highest level. It was there that we discovered that MDM is a high-tech company that bases its philosophy on solving the needs of miners, answering quickly with high quality and outstanding design solutions, while providing dramatic cost reductions and a very high network availability/uptime.

Meeting the Co-founders and its employees, discovering that the company bases its daily living in an organizational culture of respect and in favor of the development of new ideas was very encouraging. By meeting each one of MDM members we saw that they have done a splendid job gathering the best talent, with a maximum efficiency culture and with a profound knowledge in underground mining. When visiting Maestro’s clients in the field, we witnessed this excellence culture and vision towards the future actually translates into a useful and essential product for the Canadian mines.

When we returned to Chile, we started to visit the clients we already knew that operated underground mines and it was a new and great discovery to see how everyone we visited expressed how the product made sense and recognized it as a revolutionary product, with great potential to aid in obtaining their objectives and a must for underground communication. Currently, we are assuring that these fabulous products are now operating in the Chilean mining sector.

  • Easy calibration and maintenance of the gas sensors

Maestro Digital Mine provides digital solutions enabling increased production and supporting miner safety. Maestro’s global reputation of delivering robust and innovative ventilation solutions by the Vigilante™ AQS drew me towards representation of their solutions. I was thunderstruck learning about the revolutionary Plexus PowerNet™, a 1G network solution using a single coaxial cable suppling power and data.

A total solution for underground mines, reducing their CAPEX/OPEX budgets by 40% to 70%. Maestro Digital Mine is the real solution for your ‘last mine’ digital communications and air quality monitoring.

Maestro Digital Mine is the most progressive and supportive manufacturer that I have dealt with in many years. Their motto of "We leave no one stranded" is real and sincere.

Right from the product design, understanding of mine ventilation requirements, ease of implementation and support after the original sale - Maestro is a top notch organization.

I would recommend this manufacturer to any company that is serious about providing well designed equipment for the underground mining sector.

To Who it may concern,   

Cypress Sales was established in 1991, and in the years since that time we have proudly represented many high quality product offerings. We strategically align ourselves with high quality product offerings and pride ourselves in providing very high levels of service both before and after the sale. We recently added to our portfolio of products “Maestro Digital Mine”.  It is already very evident to me that both Michael Gribbons and David Ballantyne share our vision on the importance of Customer service and satisfaction. Both Michael and David have been readily accessible, knowledgeable and willing to help with any requests for support. They clearly have an immense amount of knowledge not only as it relates to their products, but the mining industry itself.  In every interaction so far they have been a joy to deal with.

I look forward to many years of mutual success with Maestro!

Re: Letter of Recommendation

We are happy to mention that after almost 6 years of business with Maestro, we are more than satisfied with the product and support. The various instruments for flow and air quality monitoring perform well and our customers are happy.

There have been issues and questions on a few occasions, however, Maestro were very supportive and solved the problems to the customer satisfaction in every case.

It is very refreshing to work with a team of dedicated, enthusiastic people such as them.
