The Tandem US is mostly like the re- gular Tandem. The only difference is the black flexible plastic nose tube. This more decent look is often used for presenting horses on shows and for sales events.
The Tongue Port Snaffle gives the horse’s tongue enough room because of the flat- tened area on the port. Many horses react to this with more relaxation and chewing. Therefore this bit is perfect for horses that won’t tolerate pressure on the tongue and for those who tend to stick their tongue abo- ve the bit.
