Skyhook Helicopters has invested heavily in specialised spraying equipment to be able to carry out this service efficiently. By using our unique low drift nozzles, more of the chemical is concentrated to the target areas and therefore minimising the threat of contamination. By combining this equipment with the latest Differential GPS track guidance systems, we are able to improve accuracy and minimise overlapping applications. We feel this makes us unrivalled by any other operator in the UK today. Bracken is one of the oldest ferns with records dating back 55 million years. It is extremely resilient and with its rhizome root structure, 90% of the plant can be found up to 1 metre underground. Bracken has the ability to spread quickly and has the potential to extend its area by as much as 1-3% each year.
