We spotted Dive Rite's QRM at the 2014 Beneath The Sea dive show. This Quick Release Mount is rather clever and I am not surprised that there is a patent pending on this.
Dive Rite state it can be fitted to any of their lights and is available in two versions; a soft handmount or a Goodman handmount. I suspect that you can also fit the QRM to lights from other manufacturers too.
The QRM uses a system of rollers and bands to easily clip a light head into the mount. Once you have played with it a couple of times, it is easy to use. You can fit additional QRM receivers on your equipment giving you the option of moving a light from your handmount onto a helmet or DPV. And you can fit QRM strikers onto backup lights giving you the option of using them with the same handmount or receiver.
