Our campfire cooker consists of a 500mm firebowl which sits on a trivet composed of three ball feet, and a tripod from which hangs a cooking grill. The grill can be raised and lowered by securing the chain with a sturdy pin through the links at the apex of the tripod.
The firebowl may be used on its own of course, and the tripod over an open fire, allowing you to double up on cooking and warmth. Folds flat for transport so ideal to go in the boot of the car for trips to the beach.
