The TADD® (Training Aid Delivery Device®) Containment System is the only scientifically engineered, patent-protected training aid container built to deliver pure odor to your dog - all while keeping everything else sealed inside.
Developed for the US Army and designed by canine trainers and scientists, the TADD® brings precision and efficiency to your scent detection training. No risk to your training aid, your team, or your training results!

*All materials pass the NASA low outgassing test (ASTM E595). Developed by NASA to screen low outgassing materials for use in spacecraft, the test determines the volatile content of material samples placed in a heated vacuum chamber. If the collected volatile condensable materials (CVCM) is < 0.1 % and total mass lost (TML) is <1 %, then the material passes the NASA criteria for low-outgassing.
How the TADD® Works
Most setups need a storage container and a separate delivery method. The TADD® does both, which means fewer transfers, less physical handling of the aid, and fewer opportunities to contaminate something.
How The TADD® Odor Containment System is Made:
The jar: Glass or plastic, four sizes from 2 oz. to 12 oz. Transparent, so you can actually look at your training aid and see whether it's decomposing or crystallizing without opening anything.
The membrane: PTFE with a hydrophobic and oleophobic coating, held in a polypropylene holder with a safety grid so it doesn't get punctured. Odor passes through it - liquids, solids, particulates, and hazmat do not!
The lid: Gas-tight and chemical-resistant. On between sessions so your aid isn't off-gassing in storage. Off during training so the dog has access to odor.
Backed by Independent Testing
All materials pass the NASA low outgassing test (ASTM E595)! Load it, seal it, and use it. The TADD® is patented, independently tested, and documented. Third-party test reports, published research, and patent filings are all available on this site. We also publish what we're currently working on!
Keeps the Target Odor In - Keeps Everything Else Out
We and our incredibly creative customers have buried the TADD® in sand, soil, and rubble piles. They have submerged the TADD® in lakes, rivers, and toilet tanks. And, of course, they've performed all of the traditional operational hides in vehicles, warehouses, luggage, cargo, buildings, open areas, and medical settings.

TADD® FAQs
What is a TADD?
The TADD® (Training Aid Delivery Device) is a patented containment system for detection dog training aids. A semipermeable PTFE membrane allows target odor to pass through while sealing the training aid itself inside, so the aid stays contained during storage, transport, and training.
What training aids can I use in a TADD?
We've found no compatibility issues with narcotics, medical specimens, human remains, biological samples, and most explosives. Peroxide explosives and liquid Nosework essential oils are not compatible, and accelerants need a modified gasket, so contact us first.
Can the TADD go underwater?
Yes. The membrane is hydrophobic, so odor passes through while water stays out. For hides deeper than 9 feet, invert the TADD so the membrane faces down and submerge it slowly..
How many times can I load a TADD?
Once. The membrane, gasket, and membrane holder seat together at a specific torque the first time they're assembled, and we can't guarantee that seal on a second attempt.
