When to Use the Shorty ReproArm vs. the Regular ReproArm by ReproScan
Reproductive ultrasound is all about efficiency, accuracy, and operator comfort — and having the right tools for the job makes all the difference. That’s why ReproScan offers multiple ReproArm options, including the standard Regular ReproArm and the more compact Shorty ReproArm.
While both arms are engineered with ReproScan’s commitment to durability, simplicity, and affordability in mind, each is optimized for different working conditions and cattle types. Here’s how to decide which arm is best for your scanning scenario.
The Regular ReproArm: Your Everyday Workhorse
The Regular ReproArm is the go-to choice for most pregnancy-checking situations. Its full-length design gives the operator ideal reach and positioning when scanning.
Best used for:
Mid-to-large-framed beef or dairy cows
Standard-length chutes with a palpation cage
General herd checks on open to mid-to-late bred animals
Situations where you want full arm extension for depth and reach
If you’re scanning from behind in a well-designed setup with plenty of space, the regular arm provides excellent ergonomics and visibility down deep, reducing fatigue during long scanning days.
The Shorty ReproArm: Smart for Tight Spots
The Shorty ReproArm is a more compact version of the regular arm, and it shines in specialty scenarios. It’s especially useful as a secondary arm for smaller or short bred animals and tight facilities.
Best used for:
Short-bred animals, where the pregnancy has not dropped off the pelvic brim
Smaller-framed cattle or heifers, where standard-length arms may only need to be inserted a couple of inches
Chutes without palpation cages or where space is limited
Side-entry access or awkward scanning positions
Reminder: When using a shorty arm, confirm an open diagnosis by seeing open uterine horns, not just by not seeing a pregnancy — this is how deep pregnancies get missed.
Because it’s shorter, the Shorty is easier to maneuver in cramped quarters and helps prevent overshooting the uterus in short-bred animals.
Tips for Choosing the Right Arm
Know your cattle. Smaller-framed breeds, first-calf heifers, or early-gestation checks are often better suited to the Shorty.
Assess your chute setup. If you’re scanning in portable chutes or setups without palpation cages, a shorter arm may offer more flexibility.
Use both if needed. Many clients keep both arms on hand to quickly adapt to the herd or the environment.
