CrossingTech DC V4

The Divine Crossing V4 from CrossingTech uses a titanium bucket as the heating chamber for concentrates. Unlike wire coils, the bucket heats material evenly from all sides, which improves flavor and reduces combustion residue. Temperature is controlled through the attached mod — in temperature control mode with a nickel profile at 300 to 380 degrees Fahrenheit, the V4 produces dense vapor without charring. The bucket is removable for cleaning and can be soaked in isopropyl alcohol.

As a 510-threaded atomizer, the DC V4 screws onto any standard box mod with a 510 connection. Mods with temperature control supporting nickel or titanium wire profiles are recommended. Popular pairings include the Wismec Pico and Eleaf Rim C, both compact enough for portable use. The V4 has a cold resistance of roughly 0.5 ohms. Anyone who already owns a mod only needs the atomizer head, saving the cost of a complete device. The spring-loaded 510 pin ensures reliable contact even on older mods.

The DC V4 reaches its full potential with Arctic Fox firmware on compatible box mods. In the TCR settings, a value of 345 for nickel matches the V4 heating element. The ramp-up wattage should be set to 35 watts with a temperature limit of 200 degrees Celsius. A preheat boost of 50 watts for the first three seconds speeds up the start without scorching the material. The firmware autofire feature holds temperature without constant button pressing, making longer sessions easier. Without Arctic Fox, the V4 still works in wattage mode but lacks precise temperature control.
