This equipment was developed by Graham Callander as a direct result of competitors requests for a system that actually worked. After nearly 18 months of painstaking research and development at the Canterbury Clay Target Club in Christchurch, New Zealand, the end result is a product that has exceeded all expectations.
This is truly "equipment that competitors demand".
Since its introduction to the sport of DTL shooting in early 1999, the base product platform has been expanded to cater for American Trap, Nordic Trap, Skeet (English, American and Olympic), ZZ/Helice, Olympic Bunker/Double Trap & 5-Trap, and 5-Stand shooting. CVR are recognised as the worlds leading supplier of voice activation systems and this equipment is used in almost every major international competitive event, along with the majority of domestic and national shoots.
Canterbury Voice Release is dedicated to developing and selling clay target release systems. The latest product is a wireless version of the standard DTL/American Trap unit. Again, the product was developed at the request of shooters to cater for handicap events where cables across the field were both annoying and potential hazardous. After 2 years of development this system is now perfected and becoming the unit of choice for many clubs
Product Development
Graham Callander began development work on the Canterbury system back in 1992 and with his scientific approach as to how the end product should work, he took a no-compromise stance on performance.
That is why you now see a product that has no dials, knobs or settings that require the equipment to be "tuned" in to its surroundings. Other than an 'on/off' button (and for Skeet - the shooting sequencer) the DTL/American Trap unit is simply - switch it on and use it! Nothing could be simpler.
Once used by competitors, they will not go back to a manual puller. As one Australian commentator said "this is one of the biggest steps forward in the history of clay target shooting. It rivals screw chokes and comb stocks in terms of technical advancement".
The same philosophy has been applied to the more complex units that operate Olympic Bunker, ZZ/Helice and 5-Stand where target sequences have to be loaded. The control panels are all straight-forward and simple to operate.
Product History
Graham Callander has had a distinguished career in analogue and power electronic research and development in New Zealand. As a non-shooter, Graham's emotional detachment from the sport meant a very critical and constructive approach was assured to this complex piece of equipment.
Extensive testing was carried out in all types of weather conditions - heat, wind, rain, snow, etc. The system then had to almost completely eliminate releasing on background sounds - traffic, airplanes, dogs barking, etc and range noises - gun breaking, shotgun blasts, referee calls, etc. Then the system had to mimic the human puller and a delay of 1/6th sec was incorporated, so that competitors would see the same release as they were used currently used to.
As can be imagined, designing equipment to these parameters was not easy - but its been done. CVR was the first to successfully develop a system that performs to the shooters' requirements, that's why our brand name is what you see at all major shoots.
