Note the DIN indicator that was added in the form of a small tab that stuck out from the housing. In the next (4th) generation this would change to markings on the spring adjustment barrel.
For more details, please see our other Dynafit (Low Tech) binding displays, perhaps beginning your browsing with the first generation Low Tech model.
Weight: 10.5 oz, 298 gr (with screws) (18 grams lighter than previous model)
