I don’t take the words “Game Changer” lightly – but this copper band is absolutely changing the Dynavap experience.

While new vaporizers like The Anvil are borrowing concepts and interfaces from Dynavap while extending and improving the vapor, they’re doing so with expenses of clunk and complication. The Simrell FMJ delivers an extended-release experience to the Dynavap with a simple $10 add-on. See the full FMJ vs Anvil 2-fist Tuesday video.

Simrell FMJ for Dynavap (copper full metal jacket)
The FMJ or Full Metal Jacket is a simple copper band that wraps around the Dynavap tip. The copper acts as a thermal battery, delaying and intensifying the extraction while removing the need to rotate while heating. Available for $10

Installing the FMJ

No tools are needed for installation. The FMJ slides over the Dynavap cap and snaps into place.

Captive caps are *highly recommended* as copper holds heat longer and you do NOT want a hot FMJ-wrapped cap falling onto your lap.

Orient the FMJ on the Dynavap cap so the S is upright when placed vertically on a storage magnet.

Using the Dynavap with FMJ

Heating the Dynavap just got easier! With the Simrell FMJ installed, aim your torch at the Simrell S logo. The copper band conducts heat much more efficiently than typical Dynavap materials and there is no need to rotate your device as you heat.

Just keep your torch aimed at the S until you hear the click! Once you hear the clicks, it’s go-time. Whether you packed tight or loose, your FMJ-enabled Dynavap should deliver a solid 30-60 seconds of satisfying vapor.

How does it Compare?

Compared to the OG Dynavap tip, the FMJ is like the Iron Man suit.

It turns the Tony Stark Titanium Tip into a Copper Clad Cannabis Champion.

It completely kills the agility, but the Dynavap wasn’t really a scalpal type of a tool anyway.

See my Anvil vs FMJ comparison to see how it compares to the Vestratto Anvil.

Removing the FMJ

If you ever decide you don’t like the FMJ and want your Dynavap’s thermal agility back, the copper sleeve can be removed by simply prying and separating the small opening in the back. A flat screwdriver works if you don’t have a spudger.
