The Crossing Core is a portable electronic rig-style concentrate vaporizer that features manual/automatic heating cycles, adjustable output, haptic feedback, and multiple coil options. The Core includes three Sai Plus coil types to get you started. Each kit comes with a triple titanium black ceramic rod coil pre-installed and ready to go right out of the box. Crossing also includes two bucket coil options (titanium & quartz) designed for ultra convenient load & go vaping. When using these bucket-style coils, your concentrate is not exposed to the heating element, preserving the taste and increasing overall efficiency.
