I'm looking for pricing information on a full digital veterinary ultrasound device specifically designed for basic laptop use. It would be great to know the features and specifications that come with the unit, including any available options or add-ons that could enhance its functionality in a veterinary setting. Additionally, please provide details on the warranty, lead time for delivery, and any bulk purchasing discounts if applicable. I'm also interested in understanding the after-sales support you provide. This information will help in making an informed decision. Looking forward to your prompt response!
