  1. Ron Willhoit

    These guys are 5 stars+. I recently rented a pre-owned Hemisphere S321 RTK Base & Rover w/Mesa 2 and FieldGenius 10 and found it to be much faster with a fix solution and enjoyed working with the FieldGenius software. I liked it so much, I bought it! Great support from Renee, the staff, are professional, very knowledgeable and truly care about providing the me “the surveyor” with best price-point purchase for a RTK Systems available. Overall, I am very happy with my purchase, the Hemisphere S321 is quick and accurate and recommend others to get a quote from BenchMark. Most Companies have a slogan, I think BenchMark’s should be “Save Money and Survey Better”.

  2. Adam Batschelet

    Excellent team to work with. We recently ordered a S321+ base and rover for RTK UAV surveys. Rene was fantastic to work with, our system was shipped one day after putting the order in and arrived promptly. System works perfect and was exactly what we needed. Communication from Benchmark is great and they have been a pleasure to work with. Highly recommend Rene and his team.

  3. Roger St. Amand

    Rene and the folks at Benchmark have provided excellent service both during and after the sale to get us set up with the Hemisphere S321+ system. Very responsive, and knowledgeable. So far we are happy with the equipment and very satisfied with the service.

  4. Sid Sandback

    We purchased the Hemisphere S321 this summer and have never looked back. We use it extensively for Equipment Construction Foundation Layout. I was able to quickly and accurately layout 130 pile locations and footings for the entire conveyor support system in our project. This includes x – y coordinates and also elevations. Forming locations and insert locations within millimeters. We found the S321 to be a ‘Game Changer’
    Rene and the staff at Bench-Mark were beyond helpful to make that learning curve as short as possible. They stand behind their equipment to the fullest as well. Much appreciated.

  5. Jeff Brown

    Recently, the company I work for purchased equipment from Bench Mark Equipment and Supplies Inc. which included the Hemisphere S321 GNSS Smart antenna, base station and the Field Genius 10 software package. When we first started using the equipment we incurred some challenges initializing the equipment. The Technical Support Team not only provided a timely response, but the advice provided was very thorough and accurate. Through problem solving at both ends, we learned that there was a small issue with the factory settings. This was resolved quickly.
    I would highly recommend purchasing equipment from Bench Mark Equipment and Supplies Inc., they are extremely professional and helpful.

  6. Carlos Alvarez

    Rene and his team at Bench Mark have excellent customer service, before buying the S321 and improved after having bought it, always with solutions to all the doubts we have had with the S321, because at the time of purchase we had no experience in gnss. We are grateful for the freedom we feel to ask when every question arises and for the quick response.

  7. Surfer Stuf

    I upgraded my complete RTK system with Rene and the boys at Bench-Mark. Great dealing on the trade-in, knowledgeable support, and well worth getting into Hemisphere’s S321 receivers. A good survey company is better now.

  8. Stephen Lane

    An excellent Company providing responsive service. I particularly appreciate the capability of the S321 RTK system. A very quick and responsive GPS system that acquires an accurate fix even in difficult bush conditions. Equipment up grades are easy to do and customer support is readily available.

  9. Andy MacDonald

    The Bench Mark team has great customer service and we have had good experiences using the Hemisphere S321 unit in our coastal and precision agriculture work.

  10. Trent Kaczur

    Bench Mark outfitted our company with the Hemisphere S321 GPS Base and Rover to fulfill our construction survey needs. Rene and his staff make themselves available to answer any questions our company may have about the gear in order to keep our work moving forward. Thanks Bench Mark!

  11. Jamie Bordelon

    Very good experience purchasing my Hemisphere S321. The team at Benchmark was very knowledgeable and the product works great!!

  12. Rob Camirand

    For the past few years, I have been utilizing the S.321+ unit, transitioning from a different model. My primary application of this device has been in establishing ground control for UAV-based photogrammetry and LiDAR operations. Throughout this period, the S.321+ has demonstrated exceptional performance and reliability. Additionally, the support and assistance provided by the staff at Benchmark have been commendable. Based on my experience, I confidently recommend the S.321+ for professionals in similar fields seeking a dependable and efficient solution.

  13. Benoit B

    The S321 is a great unit.

  14. Peter Llewellyn

    A great unit. Did even better near trees compared to other GNSS Equipment I’ve used in the past. I will definitely recommend it to others.

  15. James Kenny

    Just an update, well Rene it’s the best built GPS I’ve ever used, I’m completely impressed with the design, the radio is way better now, and since the S321 firmware update it’s repeatability and accuracy has been dead on!

    Also this Mesa2 works awesome in every aspect daylight, it’s viewability is like nothing else on the market and in wet conditions the screen works flawlessly.
