DragonFly Conical Transit Base (switch) Required

DragonFly's separate switch base for its conical drippers, the CT62 and the SA62. A knob holds the water in the dripper for immersion or releases it to drain; the base comes apart in two magnetic pieces for washing. Sold apart from the SA62, which on its own has no valve; the flat Tri-Spin base does not fit it.

Notes

BREW BOYY sets the water by coffee: 92°C for naturals, 93°C for washed coffees and blends, and 94°C–95°C for Geisha. The guide gives no total time; the finish around 2:40 is an estimate for the drain after opening at 1:55.
