Now Equipped with our Patented Slo-Inject® technology

These NEW RDD Devices are designed to administer the injectable liquid while simultaneously placing a visible mark on the animal. Pneu-Darts redefined marking injection device provides both a marking function, as well as an injection function using a single-ignition system. The net result is reduced overall length and net weight of the device.  The reduction in length improves accuracy, while the reduction in weight reduces the potential for hematomas at the point of impact.

Our Injection Marking RDD Devices each contain two compartments. The forward compartment is the injectable liquid containment chamber, the rear compartment is allocated to the marking media.

How They Work

Each compartment contains a plunger. The single ignition system activates upon impact, simultaneously forcing each plunger (Forward and Rear plungers) within the body compartments to administer the injectable liquid along with applying an external mark on the animal (spraying out of the angled 5/32" holes onto the hide of the animal).

Proper Cannula Length:
Pneu-Dart recommends ½" cannula for subcutaneous (Sub Q) injections. This recommendation has been scientifically proven and has been widely endorsed by the veterinarian community. A 1" cannula or larger will yield an intramuscular injection on cattle, cervid and many other animal species. If you are unsure of what cannula length is best for administering liquid substances to your animal, please consult with your veterinarian or call Pneu-Dart Customer Care Providers for further assistance.

All of our Marking / Injection RDD Devices are equipped with our unique gelatin retention collar. Gelatin collars are comprised of an inert material retaining the device in place until the injection is made, and after several minutes will liquefy, allowing the device to fall freely from the animal.

Option: Wire barbs can be also applied as a retention device - Note if using a wire barb, it needs to be surgically removed.

Step By Step

• Marking Media Fill - Using a syringe needle, insert the needle into the angled 5/32” hole behind the Forward Plunger. With the media-filled syringe now directed (pointed) toward the tail of the RDD Device, inject the marking media into the marking media chamber.
• Medication Fill - Using a 19 gauge fill needed, ensure that the fill needle is 3/4" longer then the cannula (needle of the RDD). Fill the Injection chamber with the desired medication.

Currently, size 2cc is available for our Remote Marking and Inject RDD. Upcoming sizes of 1cc and 3cc will be available in the near future.

Users acknowledge and accept any and all liability when using this product. Extreme caution should be present at all times.

Our RDDs perform best when paired with a Pneu-Dart Projector. There is potential for inconsistent results when using projectors manufactured by other companies.
