The new Benzing Pro chip ring now with even higher speed and more memory! The Benzing Pro chip ring is based on the HITAG-S chip from Phillips. This chip was especially designed for the pigeon sport and enables the clocking of birds to be even faster and more secure thanks to extended ranges and faster data transfer. Each and every time the ring is used, a new secret code is written to the memory. In addition, the chip ring now has an enlarged 256-bit memory enabling it to store other important data such as the association number, the fancier`s name, and the pigeon number (this facility is subject to Union ruling). Only BENZING supplies the chip-code ring in three different colours - marking different classes of birds such as cocks, hens, ace pigeons, young birds, etc. Note: These Benzing rings are optimised for use in the UK. All have factory assigned prefix letters 'DA' & 'DB'. For security, they are designed to work with United Kingdom ClubSystems only.
