After a few years in the wilderness, HorizonTech have upped their game with this stylish, Duos SUB high-power tank. Featuring triple airflow slots, stunning frosted glass and a locking top-cap, the Duos SUB is a mega-tank that rivals SMOK’s TFV8 atomizer for cloud and flavour. This is a BIG sub-ohm tank that demands 26mm of space on your mod. For TPD compliance, the Duos SUB atomizer comes with a removable plug that reduces the tank’s full 5ml capacity to 2ml.

With the supplied Tiger and Quad coils, the Duos SUB tank can cruise effortlessly at power settings ranging between 80 and 100 Watts. At these power levels, cloud production is astonishing – and fully complemented by exceptional depth of flavour! For more economical e juice consumption, many reviewers have reported that the Duos performs perfectly well at power settings as low as 60 Watts.

If the big, Duos SUB coil format looks familiar, compare it with SMOK’s TFV8 coil range. Duos coils are fully interchangeable with both the TFV8 and Melo300 replaceable coil heads. While a 0.3 Ohm Tiger coil and a 0.2 Ohm Quad coil are included with the tank, the full Duos SUB coil range also includes an RTA, a 110 Watt Clapton option, and a 150 Watt Octuplet coil head! These extra items aren’t included in this package.

Like many of the latest atomizers, the Duos SUB tank’s silicone TPD restrictor takes less than a minute to remove. With the stopper removed, tank capacity shoots-up to 5ml. For easier top-filling, the Duos SUB tank features a simple, bayonet style lock. Just twist the top-cap to the open lock symbol, remove the cap and refill.

Triple adjustable airflow slots near the Duos tank base are designed to deliver a very airy draw. Wide-open airflow settings produce more than enough vapour for some fun cloud chasing. Even with full airflow, the Duos SUB still delivers great flavour!

We have this distinctive, high-performance tank in stock with either Red or Blue frosted quartz glass. A standard transparent glass section is also included as a spare.

Note: E juice isn’t included with the Duos SUB atomizer. Please check-out the tasty flavours in our E liquids pages.

  • HUGE!!!! 4

    I got this Duos tank to use with my Smok Species mod but this tank is HUGE!!! It's almost the same size as the Species mod!! So I moved it onto my Aegis, it looked ok but still MASSIVE! The build quality of the Duos is solid, heavy weight - quality. The coil pre-installed is good for both flavour and clouds. However, none of my mods are big enough to take this tank happily (top heavy issues) so I'll probably give it to a friend, who I know has BIG mods. Lucky him cos overall it's a very nice tank, just not for me. From now on I ALWAYS check dimensions before I buy! No probs whatsoever with ordering from Go Smoke Free - delivery spot on as ever!
