Intro

The advertised specs may present the Argus MT as a cheaper version of the Vaporesso Armour Ultra, which despite a few minor annoyances, I've found to be a very useable Dimitri mod.  However, sadly this assumption turned out to be false.

If used by nicotine vapers in smart mode only, exclusively with Voopoo PNP-TW non-rebuildable coils, then the majority of MT's shortcomings would be disguised & the user would be blissfully unaware of them. However, when used to drive rebuildable coils, & in particular for Dimitri requirements, it quickly becomes apparent that the MT has serious firmware flaws, which greatly compromise its viability.
Therefore, despite an imo extremely impressive external look & feel, sadly, I cannot recommend the Argus MT for Dimitri, unless you really cannot find anything more suitable.

Although the Argus MT has an internal battery, Voopoo released an external 18650 version (the Argus XT), with identical functions, apart from a different lock switch*.  I haven't tested the XT but would expect the MT issues to also apply to it.

*Reports of faulty lock switches on the XT are common, but the MT (which has a different lock switch) doesn't appear to be affected.

Features

Stunning External Appearance/Feel Massive hats off to Voopoo for a genuinely amazing external package.  I utterly love the external shape, materials, design and overall appearance of this mod.  I only wish that other manufacturers would take note and raise their game to match this kind of amazing presentation

Internal Non-Replaceable Battery The claimed 3000mAh appears genuine (I actually tested mine at 3500mAh). 

Hinged USB Port cover. What appears to be the bottom button is actually a low-hinged flap, having tiny sprung balls/recesses to retain it when closed.  IMO, highly impressive, although a slight rattle when shut suggests it's a dust cover rather than a waterproof seal. Miles ahead of Geevape's dreadful bendy silicone USB cover flaps.

Lanyard Hook I can't envisage anyone fitting a lanyard, but I really like the way the hook protrudes from the top and allows a looser grip on the mod without risk of dropping.  Nice.

Lock Switch This is a two-position slider in the display window. Sliding to the right disables all buttons (apart from powering up/down).  The Argus XT version is a little different, having a 3 position equivalent mounted just above the fire button.  Unfortunately, a common problem results with XT being stuck in the lock state, irrespective of switch position.  Googling around suggests that a firmware update was available which disables the lock switch altogether (although this no longer appears on the Voopoo website). Alternatively, the mod can be dismantled, and the switch module bypassed (see links to utube vids below).  Thankfully, this problem does not seem to affect the MT.

Smart This is the only mode in which the Wattage auto-set should be active. Upon coil detection, Wattage is automatically set to a value depending upon the measured coil resistance. Wattages correspond to one of three possible Voopoo PNP-TW non-rebuildable coils. TW15 (0.15Ω ) = 65W, TW20 (0.2Ω ) = 50W and TW30 (0.3Ω ) = 35W. In this mode, the highest user-settable Wattage is restricted to the maximum nicotine rating of the PNP-TW coil that's assumed to be fitted, TW15 = 80W, TW20 = 60W, TW30 = 40W. This user restriction on max wattages is the only functional difference between Smart and RBA modes

TC (TI, NI and SS) Temperature control modes.  As I neither use nor recommend TC mode, I've only performed limited testing on the Argus MT.  However, my conclusion so far it that it's spectacularly bad for emesh and although I haven't yet tested for ejuice. I can't really imagine it much better.  Setting up with the Hadron Mesh RDSA with emesh TC settings of 200°C / 25W, the meshes pulsated bright red every ~1.5 seconds throughout the fire cycle, which is clearly unusable.  In addition, there is no real-time display of wattage, calculated temp or resistance during the fire cycle, which imo removes any last shred of hope that this mod might perform any credible TC function for Dimitri.

Pros & Cons

🙁 Unacceptably Buggy Firmware - It's genuinely hard to say anything positive about the functional operation of this mod, so I suggest avoiding for Dimitri use.  If you do buy one, then take care when changing tanks (and changing modes) as in any mode (apart from TC), the wattage will change to a value that you almost certainly don't want.

🙂 Quality external look & feel

🙂 Unusually bright display and Wattage text field

The Argus MT's Stainless Steel Firmware Bug Explained

Recap

The SS bug is caused by a mod failing to adjust the coil's Voltage up (during a fire cycle) to maintain the desired Wattage as coil's resistance increases naturally with temperature.

The Z50, Thelema Solo/Grus quest and Geekvape Max V1 (which all have this bug) take a resistance measurement when a Fire button press is detected, and calculate the Voltage to apply for the entire fire cycle using this formula

Volts =  √ (Wattage setting x cold coil resistance measured immediately upon Fire button press detect)

This is fine for Ka1 and Ni80, as these don't increase their resistance with temperature, however with stainless steel the increased resistance of a hot coil results in a dropoff in power.

On the Argus MT

As far as I can determine, the Argus MT reads coil resistance only when a new coil is detected.  Therefore, for its power modes (Smart, RBA, and Turbo), the fire cycle Voltage is fixed at a value calculated upon the "new coil" value as follows

Volts =  √ (Wattage setting x new coil resistance measured only upon "new coil detect")

In fact, this makes the bug a little more predictable, as (unlike the mods mentioned above) a quick off/on button pulse during a fire cycle doesn't cause an updated resistance reading (on a hot coil) to instantly boost the delivered power.  So for the Argus MT, when using SS coils, simply multiply the desired Wattage by 1.2 to find the approx Wattage to dial in to the mod. There's no concern about effects from accidentally pulsing the button.
