- Warning: this is a rant *
The flash first appeared in European dressage, oooh, 25 or 30 years ago, where young horses are produced to sell for high prices and the strap is designed to keep their mouth shut to hide resistence, the lack of acceptance and gaps in training. From there, following fashion, every bridle acquired a flash noseband. The issue is that no one quite knows how to adjust it: which way it goes around the nose; end of strap pointing up or pointing down; the position of the buckle. There is permanent confusion amongst riders.
If the horse is accepting a contact and the rider has sufficient skill to have “good hands”, then the bit will be still in it’s closed mouth, often without any noseband. “Taking the bit”. If a horse does have a busy mouth then a correctly adjusted figure of eight or grackle will possibly/probably do a better job than a caveson pulled downwards out of shape by a flash attached to keep it down and so making a ‘sort of’ figure of eight. And to fit and support the flash, the caveson goes too high on the face applying pressure on a sensitive part of the head, just at the base of the cheek bones.
If you ask around, a distressing number of riders will tell you that the flash is designed to stop the bit “falling out of the horses mouth”. Struth!!!
In days of my youth, when Noah’s flood was still merely a distant weather warning, the trendy noseband to assist a young horse was the drop noseband. They can also be difficult to fit correctly.
It is interesting to look at headshots of top horses in the 1960s and 70s and see how unconfined their heads are.
Some people, however, love a flash.
