The Titanium version is known as the limited edition of the Pioneer MTL RTA by BP MODS. The Pioneer MTL RTA is featuring a 3.7mL capacity, conical flavor chamber, and an interchangeable bottom 510 pin airflow system. Constructed from superior stainless steel, the Pioneer RTA can hold up to 3.7mL of eJuice within PCTG or ULTEM glass. Equipped with a single coil build deck, the Pioneer RTA vents directly below the coil structure with a threaded 510 pin airflow intake that can be changed without removing any coils, eJuice, or cotton. Covering the dual post build deck is a conical top cap, funneling vapor and flavor directly to the tongue, allowing the Pioneer RTA to extract the best flavor from your favorite e-liquid.
