“I have used the same Stone Mountain Sword speaker mic on my Kenwood radio since 2007. It’s been used and abused in structure and wildland fires, water rescue and all forms of inclement weather. I am especially impressed with its waterproofing as it has always been loud and clear even when wet (We get torrential rain here). It has never failed me once and after having used a variety of speaker mics over the years, I now would never use anything else on my radio for the Fire Service.”

“Western Taney County Fire Protection District has used the Stone Mountain SWORD for 5 years. We were looking for a lapel speaker mic that would hold up to firefighting conditions. The SWORD has done just that – Truly a water proof product that has good sound and lasts. Thanks to the team at Stone Mountain for helping solve our communication needs.”

“Bedford County Fire & Rescue is pleased to continue our relationship with Stone Mountain Ltd. as we provide our volunteers and career staff with the latest radio communications technology. After several weeks of field testing we selected the Phoenix speaker mic to issue to approximately 250 of our personnel because of the product’s overall quality and the ability to upgrade them with the CallCheck feature. As a bonus, Stone Mountain is located in our county, which gives us the ability to interact with them easily.”

“We contacted several after-market microphone manufacturers to build a rugged shoulder mic with a Nexus connector for use by our Helicopter Crew(s). This required a custom mic that contained switching, so that the user can unplug his helmet mounted headset from the on-board intercom and plug into the shoulder mic to operate in the high noise environment near the running helicopter. To make things even more problematic, we employ several brands and models of radios, Motorola, Harris and Kenwood.
Stone Mountain was the ONLY manufacturer to accept the challenge. All the others told us sorry we don’t make anything like that.
Stone Mountain rapidly developed a prototype based on their existing designs that we’ve tested in the field and are very impressed with ruggedness and operability of the mic. The cost is less than we can build them ourselves.
The Stone Mountain solution meets or exceeds all of our product requirements.”

“Stone Mountain is a great business partner and always provides excellent customer service – couple this with their industry knowledge, excellent design, and quality product and you get a great all around company to do business with. No matter the size of your order they treat you as their only customer and that is really appreciated. We will continue to do business for years to come.”

“We own a fleet of 550 concrete trucks – Nine months ago we migrated our vehicle communications to a cellular based system using pedestal mounted Android tablets with the Zello PoC app. We operate in an extremely loud and environmentally hostile environment and needed a wired remote speaker mic (RSM) that was rugged, waterproof, extremely loud and reliable. After evaluating several product options, we chose the Phoenix Elite RSM by Stone Mountain. The Phoenix Elite met or exceeded all our requirements and expectations. The unit maintains loud and clear audio well above the ambient noise level. The hard wired charging kit is easy to install and includes a heavy duty power connector that conveniently mates to a jack in the RSM cable – Allowing the RSM to be charged and used at the same time.
Stone Mountain worked with us more as a partner than a supplier – They listened to our needs and if they didn’t have it, they developed it for us. Their customer service and product support is truly exceptional!”

Logistics & Transportation
“Due to coverage problems with our old CB radio platform, we switched to a mobile phone system using a Kodiak push to talk over cellular app. We are a non-profit organization with 80 buses providing Medicaid and public transportation services in sixteen counties. As such, we are required to follow FTA distracted driving regulations and for the safety of our drivers and passengers chose a wired speaker mic to use with our tablets. Several different brands were evaluated, with the clear winner being the Stone Mountain Phoenix Elite. The product is extremely rugged, high quality and LOUD! It also allows us to charge the unit during daily use. The Stone Mountain engineers helped us solve system implementation issues throughout the project. We love our new system and the Phoenix Elite has proven to be very user friendly and reliable. Many thanks to the team at Stone Mountain for their products and support!”

“In order to communicate effectively, real time and hands free, we previously tried various VOX solutions without success. We heard about, and subsequently evaluated, the Stone Mountain SpeakEZ hands free, full duplex communication system. The units are extremely user friendly, compact and possess excellent Rx and Tx audio quality (a strict requirement in our business). The ability to have five people talk simultaneously in full duplex was a huge plus for our various venues.”

“Engineering and maintenance in a healthcare environment is critical to the services we provide to our patients and colleagues on a daily basis. Quality of care depends on our quick reaction, and the reliability of the tools we use. We can’t afford to hesitate or miss the opportunity to respond. This is mission critical for everything from high end equipment used for life support, general maintenance, and fire response. We’ve tried the Stone Mountain Phoenix microphone and found it met and in many cases exceeded our expectations. They have a great product and are passionate about meeting the needs of their customers. As such, I would personally recommend Stone Mountain and I am looking forward to working with them in the future.”

Aviation & Maritime
“Linden Municipal Airport is a Federally Designated Reliever Facility for the Newark International Airport and the helicopter center for the New York City area. We are a busy general aviation airport and are responsible for managing all aspects of the facility including aeronautical and ground operations, aircraft fueling, and airport maintenance. Reliable communications are vital to keeping our people safe.
We need to protect our personnel from the extremely high noise levels, particularly around running helicopters, when they are outside handling operating aircraft. Our people are equipped with very heavy-duty noise cancelling industrial headsets attached to extreme duty hard hats. When going indoors, or inside a vehicle, they need to transition to a speaker microphone. Frequent changing back and forth became a frustrating, time consuming process, with the staff constantly fumbling with the equipment. Further, the constant switching between headset adapters and speaker mic units was causing repetitive connector failures on the radio units.
We needed a system that would allow us to connect the headsets directly to the speaker mic. This would eliminate the wear on the radio connector and allow the staff to keep the radio unit and speaker mic in place on their person. Ours is a very tough environment and finding a solution was not as simple as it sounds.
We tried numerous speaker mic units. Those few that had a connector that would actually mechanically mate with our heavy duty headset’s plug all had poor auxiliary headset connectors. They were decidedly inadequate in our environment and failed quickly. Some had poor audio, impedance mismatches, or other technical incompatibilities. Worse, the manufacturers had little understanding of these issues.
I was referred to Stone Mountain, Ltd. Their engineers were clearly experts and very responsive. They immediately grasped the mechanical and technical issues with our application. I provided one of our headsets and a radio unit to them and within a week they supplied a fully tested Waterproof Phoenix Speaker Mic with the SureTact feature and a custom interface cable to interconnect the headset to their speaker mic.
Their speaker mic units have held up very well, even in our environment, and the staff is very satisfied with the high audio quality they provide.
We have since purchased additional units. I would highly recommend you consider Stone Mountain for your communications needs.”
