Digiflavor Bucho tank intro

The Bucho sub tank is a collaboration between Digiflavor and George Batareykin, one of the most popular Russian vaping Youtubers, and also the man behind a large Russian-language vaping forum. In George’s own words, “I don’t like to build coils, I want an easy to use sub ohm tank with really good flavor.”

The result is a 25 mm diameter sub ohm tank with 3.3 mL capacity. It comes with two coils in 0.25 and 0.5 ohm resistance. The tank is said to be compatible with other BVC type coilheads, but Digiflavor doesn’t specify which ones.

The Bucho tank is selling online, with prices ranging from $16 to $30. Replacement coilheads are harder to find right now, but five-pack will set you back around $8 from some China shops.

Let’s try out the Bucho tank and see if it’s as tasty and simple as George hoped…

Notable Remarks

Machining / Fit and Finish

Black-Digiflavor-Bucho

The Bucho tank comes in a simple box, marked with Digiflavor’s typical branding as well as George Batareykin’s signature logo. Inside you get the tank, a replacement glass tube, two coils, o-rings, and a simple user manual.

The tank consists of six parts: the base, glass tube, coilhead, top fill chimney, top cap, and Delrin drip tip. The base has two Cyclops-style airflow slots, and the adjustable airflow control ring has gears that fix it in five settings, from open to closed.

The Bucho is a top-fill sub tank, and the two large slots around the chimney make filling the tank straightforward. The top fill chimney is connected to the top cap by threading around the outside of the chimney. The top cap has some minimalistic knurling around it.

To cap it off, the Bucho has a 510 drip tip made out of Delrin. This has a fixed 8 mm inner diameter but is wider at the base, making it appear slightly concave. The drip tip simply slots into the top cap without any o-rings to hold it in place. It is a snug fit.

The tank is stainless steel with an anodized black matte finish. Most parts slot together with the aid of o-rings, and what minimal threading there is feels very smooth.

The Coils

Black-Digiflavor-Bucho

The Bucho takes BVC coilheads, rated at 0.25 and 0.5 ohm. The lower resistance coil has a recommended wattage range of 35 – 65 watts. The higher of the pair performs best between 25 – 35 watts. The specs also state that the Bucho tank can take other BVC coilheads, but fails to specify which ones.

I can confirm that the Bucho works with Aspire Atlantis coilheads. Eleaf EC/ECML/ECL coils. Triton coils. Sense Herakles coils. And probably more besides them. That means there will be a couple rebuildable bases for those tanks that would theoretically work with the Bucho too.

All this could be good news, or a weird throwback depending on how you look at it. Still, I appreciate the idea that I’m not limited by the two coil types manufactured for the tank. Finally I’ve found a use for that stockpile of Atlantis coils lying around the office!

Aesthetics

Black-Digiflavor-Bucho

The Bucho is a chunky, compact, solid-looking tank. It makes me think of a supersized Nautilus X. It pairs really well with a solid mod that can take a 25 mm atty without looking overwhelmed – like the Geekvape Aegis, or the Minikin V2. There’s no frills or gimmicks to the design. It’s not a lightweight tank either – weighing a slightly more than the Big Baby Beast, it has a heft to it that feels reassuring.

Performance

Black-Digiflavor-Bucho

For this review, I vaped on the Bucho tank with The Big Easy, a 70/30 VG/PG blend e-liquid from Ohm Grown. I’m tasting a sugar frosted doughy treat. Marvellous!

I start off with the 0.5 ohm coilhead, working my way up from 25 – 35 W over the course of one tank’s worth of e-liquid. At first, the taste – and vapor – are thin, but performance improves as the coil warms up. On this coil I wouldn’t vape below 30 W, but unfortunately the taste is already slightly burnt after one tank.

Taking the coilhead apart, I see that this is a 27 gauge single spaced titanium wire, 4 mm inner diameter, with eight wraps to it. I was disappointed by this coil, and 35 watts is a bit low in my opinion.

Moving on to the 0.25 ohm coil (27 gauge parallel build with six wraps), performance improved immensely. Although it’s rated between 35 – 65 W, I find 50 – 55 watts is perfect, with the airflow closed off about halfway. You can push it higher, but I think the Bucho tank is really designed for flavorful, mid-wattage vaping.

At this wattage, the 3.3 mL capacity isn’t a deal breaker either. The flavor and draw remind me of IJOY’s Captain sub ohm tank, which isn’t a bad thing!

I’ve also had very satisfactory performance using some of the other coilheads mentioned. My pick of the bunch so far has to be Eleaf’s EC Nickel coil at 0.15 ohm, in temperature control.

Irks

Black-Digiflavor-Bucho

Using BVC coils in the Bucho tank comes with some setbacks. The biggest irk for me has to be changing out coilheads. As far as I can see, there’s no way to do this with e-liquid still in the tank. The coils aren’t tall enough to be unscrewed either from the chimney or the base without first removing the glass. Doing this either way with juice in the tank will cause leakage.

The Bucho coils themselves have four wicking holes, set fairly high. Although they’re large enough to wick high VG e-liquids, you do have to refill long before the tank is empty to avoid dry hits. I get best performance when the wicking holes are completely covered by the e-liquid.

Although topfill is as easy as it gets, the top cap and chimney threads tend to overtighten. Unscrew from the top and you may notice the coil coming loose from the base. To fix this, I apply extra pressure on the top cap to twist it free from the chimney.

Likes

  • Solid and robust
  • Flavorful mid-wattage vape (prefer the 0.25 ohm coils though)
  • Compatible with a wide range of coilheads

Dislikes

  • 0.5 ohm coilheads are easily overpowered (and there’s no specs on the wire type used)
  • Tank must be empty before changing out coils

Verdict

For what it is, I like the Bucho sub tank. The construction feels solid and robust, and it looks good on bulkier mods. The choice of BVC coilheads (in a form which dates back to 2014 and the Aspire Atlantis) doesn’t feel very innovative. But the flipside of that is the versatility of the tank. Time to dig out the BVC stockpile, and use them with this tank.

The Bucho sub tank delivers in terms of flavor, but that’s mostly down to the coils themselves. Changing out coilheads requires an empty tank, which is annoying if you have a burnt coil halfway through.

This isn’t a revolutionary, new-concept sub tank. The ground feels well-tested and predictable. If you can pick it up for $16, I’d go for it. At $30, it seems overpriced.

    1 coil included ? Bit tight!
    Ah no, sorry, I see there are 2.
