@SquirrelMaster Thanks for the kind words about the photos! This lens I used here was actually a Canon 60mm f/2.8, but it's adapted to my Fuji x-E3 with a dummy adapter, so the lens information is incorrect on the metadata
My other lens I use a lot is a meike 35mm f/1.7. This Chinese made lens is under $100 and excellent. Very few lens elements, giving a look more like a vintage film lens. Lots of character.

Between each hit I removed the stem, put it into my camera taking setup, and snapped a quick photo. I had everything set up on a tripod, focus adjusted, etc. Then I would record the times and vapor quality on paper before the next hit. So it was probably 1-2 mins between hits. I didn't do any extra pre-heating that was not recorded. I wouldn't say that the vape returned to cold, but rather it was just warm.
Under normal conditions, I do expect that I would change the pre-heat to something like 3-4 seconds on the second hit onwards.
I used to do a 4 or 5 second pre-heat on the first hit, but now I find a 6-7 second produces vapor quicker and allows me to go right out of the gate with a faster draw speed.
Ambient room temp, just average t-shirt wearing normal.
Glass vs. Briar - I do find a difference, but I'm not entirely sure how big of a difference it makes, I go back and forth between the two methods and jump between which one I prefer. The all-glass gives you a larger chamber, which I do like, but the briar does seem to insulate the load a bit... and I think that gives faster heat up times and slightly better evenness around the outside edges.
A note about the briar chambers, on advice from
@namasteIII I have been experimenting with pre-shrinking the chambers in the oven to roast the wood. This roasting seems to stabilize the wood and cause less shrinkage/expansion in the future. I found that if left unroasted, the briar burl chambers would go from fitting snug to loose after a session and then return to near normal after sitting a few hours. The new chambers go from snug, to slightly less snug, so I'm super happy about that! These improvements have already made it into the Nomads that I have sent out this week.

@namasteIII Awesome to hear!
And your notes are definitely helpful for future Nomadics, all of this helps me to better explain the techniques.
I compared the Nomad quite heavily to the dynavap, and I definitely know what you mean by the vapor difference, it's quite drastic. I've noted, and others have as well, that conduction (or hybrid) heating produces a thicker feeling and looking vapor, for whatever reason. Effects wise, I don't find any difference given the same amount of herb, so I'm pretty confident that the extraction efficiency is comparable..... but the vapor is just different.
Also, draw restriction between the two devices is drastic! When coming from the dynavap back to the Nomad it feels like there is just zero restriction, feels like tons of air is just streaming through the thing, ha. It requires quite the adjustment.
Good to know about the tamping! When I tamp a load very lightly... It's about the weight of a pencil, ha. So it's like..barely a whisper. I find that as long as it stays in place for the first hit, that first hit will compress the load and sort of melt it all together, and after that you're safe.
About grind consistency, I am ashamed to say that I use scissors.... heh. I don't know why but it's just always been my way of doing it. I'm sure there is a better way, but that's how I do it and it works for me. It's pretty inconvenient for large quantities though. I fill up a film canister and scissor the hell out of it.
With the high heater, I aim to make it perform like the low heater. But it just get me there with less pre-heat and less time inhaling. Also, you bring up a good point with feeling the heat. I let go of the button
before I feel the heat, based on intuition. With the high heater, I think that when you feel the heat, it's too late. A very good observation there!
I will say that with the high heater you can definitely push it further much easier than the low heater into higher temp ranges, getting into those dark brown abvs is no problem. Most of the time, taming it is the problem.
@KeroZen Very interesting, excited to try that out.
@Mr. Me2 I dump directly from my herb container into the chamber, but on occasion I scoop with a little scooper, works equally good!
