The Scar Dual Coil RDA is a rebuildable dripping atomizer. It is 510 compatible and made from high quality stainless steel. This device works amazingly well and gives a strong hit with plenty of flavor. The Scar Dual Coil RDA has 2 - 3.0 Ohm coils installed that make a total resistance of 1.5 ohms. The Scar allows you to have the vape that an atomizer delivers with the convenience of being able to add more e-liquid to the well so you don't have to refill it as often. This is due to the 8 wicks per coil that soak up the e-liquid and feed it to the coil.
The coils are replaceable. They are attached to The Scar via 3 thumb screws for a quick and easy installation. The thumb screws on the outside are for one wire of each individual coil and there is a shared thumb screw in the center to complete the circuit. As some of the pictures show, there is a spare o-ring at the top of the device. This is a replacement for the 2 installed should one become worn.
These work really well. The original design being the Octopus has a great hit and produces a lot of vapor, but the Scar creates even more.
