The DMM Retrieval Cone in large is designed to fit through the Pinto Rig Pulley.
Conveniently, it also fits through the ART Cocoon and Link pulleys and catches nicely on the ART Trapeze retrieval shackle. This means it works with the ART Rope Guide. Must be a coincidence....
Small Cone = Yellow/OD 20.5mm
Large Cone = Red/OD22.3mm
Yea, it retrieves stuff err....well.
We went and put in Donaghys 2mm Spectra Speed as the cord instead, just so it's super strong ;).
