Calder Mobile 1 (CM1) is a Ford Ranger based at The Rescue Post in Mytholmroyd. The vehicle was purchased with the help of a generous donation from the Sarah Royle Trust and entered service in late 2012.

CM1 has been specially adapted for Mountain Rescue operations. It can transport up to five team members along with their personal equipment and carries our operational kit. This includes a stretcher, a full crag rescue system, a vacuum mattress, scene lighting, and advanced first aid equipment.

More recently, CM1 underwent a comprehensive refit at NorthFire in Mytholmroyd, extending its serviceable lifespan and ensuring it remains a reliable asset for the team.
