Whether you are a mobile equine vet covering miles of countryside, a dairy farmer monitoring your herd’s reproductive health, or a sheep breeder keeping a close eye on your flock, having a reliable portable ultrasound machine at your side can make an enormous difference. The SIUI CTS-800 is one of the most popular portable ultrasound scanners on the market, and it is easy to see why. Combining outstanding build quality, practical design and impressive versatility, it offers exceptional value for money for both veterinary professionals and agricultural producers alike.
At under one kilogram, the CTS-800 is genuinely portable in the truest sense of the word. It will not weigh you down during long days in the field, and its compact form means it fits comfortably into a kit bag without taking up valuable space. Yet despite its light weight, this is a machine that has been built to withstand the realities of farm and veterinary work. The main unit carries an IP64 environmental rating, while the probe head is rated IP67, meaning both are well protected against dust and water ingress. Muddy yards, wet weather and the general unpredictability of outdoor work are simply not a problem.
The CTS-800 features a bright seven-inch LCD monitor, offering a clear and sharp display across B, 2B, Zoom B, B/M and M modes. One particularly clever feature is the built-in gravity sensor, which automatically flips your image vertically or horizontally depending on how you are holding the unit. This small but thoughtful detail saves time and reduces frustration when you are working in awkward positions, which, as any large animal vet will know, is rather a lot of the time.
There are few things more frustrating than a piece of equipment running out of power mid-procedure. The CTS-800 comes with a 4.5-hour lithium battery as standard, giving you a generous working window before you need to think about recharging. For a full day of farm visits or on-site scanning sessions, this offers real peace of mind.
The CTS-800 is available with two linear rectal probe options, allowing you to choose the configuration that best suits your work.
The L5FVC (64mm, 4 to 6.2MHz) offers a larger footprint and lower frequency, making it well suited to larger animals and deeper tissue imaging. The L7FVC (50mm, 6.5 to 9MHz) provides a smaller footprint and higher frequency, giving you greater resolution for more detailed imaging work.
It is worth noting that the CTS-800 cannot be fitted with a dedicated tendon probe; however, many equine vets use the rectal probe successfully for tendon work, so this is rarely a limitation in practice.
One of the CTS-800’s greatest strengths is its reproductive software, which covers an impressive breadth of species including equine, bovine, ovine, canine, feline and primate. Combined with a comprehensive suite of measurement tools covering distance, area, circumference, volume, angle and heart rate, this is a machine that genuinely earns its place across a wide variety of clinical and farming scenarios.
If you are a veterinary practice looking to present a professional image, you have the option to have your machine preconfigured with your practice name, a thoughtful detail that costs nothing extra and adds a polished finishing touch.
Goggles are something of a talking point in the veterinary world, and opinion is divided. Some practitioners value them highly for eliminating screen glare and dirt, particularly in bright outdoor conditions. Others prefer to avoid them due to the reduction in peripheral vision and situational awareness they can bring. They tend to be more popular amongst bovine vets than equine vets, and the majority of users opt not to add them to their setup.
That said, if you have used goggles before and found them beneficial, the latest 2022 model can be added to your order for £720 plus VAT. Please be aware that orders including goggles carry an extended delivery time of approximately two weeks.
All CTS-800 units come with a two-year manufacturer’s warranty as standard, offering reassurance that your investment is well protected. When you are relying on a piece of equipment day in, day out, that kind of backing matters.
If you are looking for a portable ultrasound machine that delivers professional-grade imaging in a robust, lightweight and genuinely field-ready package, the SIUI CTS-800 is an outstanding choice. It is cost effective without cutting corners, versatile without being complicated, and built to keep pace with demanding agricultural and veterinary work.
