National Polygraph Academy - “I have conducted criminal specific computerized polygraph examinations for over fifteen years of my twenty five years in polygraph. I’ve utilized several of the other systems over the years and the Limestone Professional Polygraph Suite is by far the standout system on the market today. Limestone Technologies made the smart move to create a system that incorporates the latest technologies, while removing the shortcomings and problems found in the other systems on the market. Their medical grade components and connections, innovative real time integration of audio/video collection and intuitive software design has pulled computerized polygraph into the twenty first century.” Milton O. “Skip” Webb Jr. Past President,
American Polygraph Association
- “Plunging/unreliable EDA, serial to USB Flip Chips, cannot find DAS error messages and poor customer service are a thing of the past. Limestone’s instrument truly does deliver the best results.” David Reisinger
- “For the past several years, my agency has utilized various polygraph systems. In 2009, our polygraph group was provided a Limestone polygraph presentation, which left us all completely in awe. We then checked with other federal agencies, who had already utilized Limestone polygraph systems, and everyone echoed the same thing “great customer service.” We decided to make a purchase of multiple Limestone polygraph systems, and it has been money well spent. The graphics and the versatility of the system is better than any polygraph system that I have ever used, including Lafayette polygraph systems. Limestone is by far the best polygraph distribution company out there…if you don’t believe me…just call them and see for yourself!” SA LeMar “Tony” Sims US Postal Service/OIG, Quality Control Supervisor
- “I wanted to let you know, and also say thanks, that at my recent polygraph board it was commented how professional my charts looked compared to the others on the board. My peers had Lafayette instruments while I had Limestone. From what I’ve been told by the others with Limestone, the consensus was the same. I am very pleased with my instrument as well as being immensely impressed with the customer support/service you’ve displayed. Although issues have been very few, and on the fault of State operated computers not the instrument, the response time has been within minutes. The follow up by your staff was both pleasant and unexpected. Im sure you are aware but let me assure you that your instrument is astounding. Thanks again and I look forward to doing business with you in the future.” Major Jacob Falgout LCIW Safety Officer, LLSA
- The new website looks excellent….just like everything Limestone does. Keep up the good work! As I always tell all of the vendors, it does not matter how good your product is or how pretty your website is.The bottom line is customer support. When a client has a problem, do you answer the phone? You sell a product that is vital to public safety and when there is a glitch, it needs to be fixed RIGHT NOW! Limestone has always been excellent at that as well! Ted Todd TTI Polygraph, CA
- “Thank you for helping us and your ongoing technical assistance (24/7 and I do mean 24/7) whenever we have a problem whether it be equipment or software you guys have always been there for us. Lafayette or Axciton can’t touch you in this area when it comes to customer support!” Isaias Menchaca Homicide Investigations, Contra Costa County DA
- “Your customer support has been second to none and we haven’t even really gotten off the ground. It is good to know that we have a company like yours standing behind us as we begin this Criminal Justice journey.” Moises Velazquez Special Victims Unit, Miami Police Department
- “Recently, after being very frustrated with one of the other polygraph companies, I switched to Limestone Technologies. I attended Jamie’s excellent presentation at the NPEA Summer Seminar and that was all the ‘push’ I needed. Every examiner in my office now runs Limestone equipment and we all are very satisfied. We feel that Limestone offers the ‘cutting edge’ in polygraph instrumentation and research. If anyone is considering buying a new computerized polygraph, call me and we’ll talk. I’ll tell you why I looked at everything on the market and went with Limestone.” Chip Morgan Boise, ID
- “I have been using the Limestone system exclusively for some time now, and I’m very impressed with their commitment to providing solid technologies based on documented methods. Limestone’s service and support have been outstanding. The quality and usability of the data are excellent, and the software has proven very stable, with an impressive range of usable features.” Raymond Nelson Denver, CO
- “Unlike other polygraph manufactures, Limestone has and continues to offer software enhancements that expand the quality of the polygraphs features and capabilities. Your desire to better serve clients and provide the new standard of polygraph instrument is going to bring many polygraph examiners to you. Why purchase a Flintstone polygraph when you can get a Limestone!” Robert Hamilton Miami, FL
- When I first switched from analog to computerized polygraph of another manufacturer in 2004, it was just like a switch from driving a manual car to an automatic car. But when I switched to Limestone polygraph suite in early 2006, it was like switching from a basic automatic car to one with sports-shift (triptronic). The experience was totally different. It was so powerful and easy to use. In every test there is no worry that I may not get a good tracing due to bad instrumentation. In addition, the Limestone polygraph suite is packed with many advanced and useful features. Some of my favorites are the ability to display both the raw & auto EDA concurrently, clear discernible tracings always, uncapped range for tracing sensitivity, and above-all is their unequalled customer support.” Daniel Kor Singapore
- “Merci beaucoup Limestone Technologies! The quality of your software and instrumentation is outstanding. I am equally impressed with your after sales service, both over the phone and via email. You really demonstrate that each order does matter and that customers are important.” John Galianos Quebec, Canada
- “Once again thank you for a professional and very supportive service, I am a Limestone user for life, as you know I had been in this business for years and used all instruments from analog, dos, windows, thanks for the Rolls Royce.” James Fourie South Africa
- “I am writing to you and Limestone to express my sincerest thanks for your instant return call over this last weekend when I had a software issue. I contacted your technical support on a Sunday morning requesting assistance. I had an attorney enroute to my office to bring a client in for an urgent test when I ran into a technical problem. I didn’t expect to get an immediate return call from the company president, but you called me at once and guided me through what I needed to do to correct the problem completely. Once again, Limestone has shown that it’s customer support is second to none. Over the years, I have utilized equipment from all the other vendors and none of them can come close to equaling your outstanding customer and technical support. You guys come through every time! I will continue to recommend Limestone to everyone I know as by far and away the finest polygraph company in the business.” John Swartz Houston, TX
- “I currently am using the Limestone for my work as a Detective Lieutenant with the Cook County Sheriff’s Police Department in Maywood, Illinois, U.S.A. and I have been impressed with what I have been able to do with it so far. I have used analog polygraph systems and have used the Lafayette and the Stoelting computer systems. We, as a Police Department, had purchased Lafayette systems about six years ago and they had their use until we discovered something better. Fortunately, in the summer of 2009, we purchased five Limestone systems from your company which are in use everyday by us (both screening and criminal examinations). In that short time, my fellow examiners and I are sold on the ease of use and the professional charts produced by the Limestone systems and look forward to administering a record number of examinations with these systems. Your company’s presentation at the APA seminar in Nashville, Tennessee helped tremendously in learning how to learn and access all of the functions of the Limestone System. Thank you.” Detective Lieutenant Sean Gleason Cook County Sheriff’s Police Department, IL
- “James, you and your company have provided exemplary service each and every time we have required assistance. Thank you for your service and for remembering your clients/customers throughout the years.” Sergeant Mark Bonfield Internal Affairs Unit, Colorado State Patrol
- “As a polygraph examiner with more than 26 years of experience I have had the opportunity to use all the manufactured polygraph instrumentation. My fellow office associates and I now only consider one choice. The Limestone Polygraph Professional is truly the best. The chart data quality is exceptional and the software has proven itself to be reliable and easy to learn. The promptness of your service when requested is immediate and thorough. Limestone Technologies has raised the bar and the professionalism is a refreshing bonus”Dr. Richard Poe Largo, FL
- “Regarding Polyscore: My experience with it was a year ago when I had a Lafayette. The results were mixed and I found that, on occasion, I would make a call that did not agree with the Polyscore. Things may have improved in a year (or maybe it was just me). I finally decided to do away with it altogether when I began to think about making a call that differed then having to defend my call against Johns- Hopkins. I use a Limestone now, without a Polyscore, and have been very pleased”Wayne McBride McBride Truth Verification Services, CA
- “I have been using a Limestone Instrument since starting my own business and have found it to be dependable and user friendly. I have used other brands of computerized polygraph in the past and would not go back. I bought Limestone because it was user friendly but I will keep and recommend it to everyone because of the service after the sale. I have called for assistance and received instant service. I have also been kept up to date with the latest upgrades as they become available. Thanks Jamie, Tyler and Brad for a great product! Dennis Rankin Evans, NY
- “Limestone Technologies Inc. has been a great company to deal with, especially with all my technical issues. The Customer Service is the BEST in the business, and the most professional staff to help with all your needs. As technology advances as well as techniques, you can be certain that Limestone has a solution for any problem for the Polygraph Examiner” Chief Daniel Torres Lincoln County Sheriff’s Department
- “I too am very pleased with my Poly, and don’t know why I waited so long to get the Limestone Model. If anyone is considering buying one…. BUY IT. The customer service is excellent” Mike Hodge
- “Sir thank you kindly for your assistance you saved me some gray hairs. I have never dealt with any company that provides such GREAT service! Thanks again” Ernest Myatt Sr. Belleville, MI
- “I just wanted to say thanks for making such a terrific instrument. When using the Lafayette and Axciton instruments in polygraph school, I remember having a difficult time getting the charts to ‘look good’ for closer evaluation and even for printing. Polygraph Professional Suites ability to change any tracing globally through the test is a wonderful feature. It helps me analyze the ‘tough comparisons’ at several different sizes and know that the integrity of the actual tracing is still in tact”Ralph Hilliard Owner, ThePolygraphPlace.com Powder Springs, GA
- “I have been a Limestone customer for nearly three years. I have used every other instrument available, with the exception of one. By far, the Limestone Professional Suite is the best instrument on the market. I am simply amazed that the professionals at Limestone have taken the lead in the industry in such a short period of time. They have accomplished more in a few years than other manufacturers have in decades. The Professional Suite software incorporates the most user friendly and technologically advanced product in the polygraph field to date. The ChartSync feature works without a hitch. It is extremely advantageous to have the audio/video aligned with the physiology. This makes the detection of countermeasures much easier for the examiner. The customer service is second to none. With another manufacturer, I waited over a week for a reply from their support staff. With Limestone, Jamie and Tyler were on the phone with me immediately. They posted a fix on their web site within thirty minutes and solved my problem. I was astounded to find out they did so while they were conducting a training seminar away from their offices. I can’t imagine any better service anywhere. Limestone has made a lifelong customer. Thank you so much for your continued dedication to this important field” Mike Calderwood Coeur d’Alene Police Department, ID
