All of this is exactly what came to mind for me too.You don't mention using the carb cap, that's probably the missing link. If you are using a carb cap then it sounds like it's time to replace your coil.

Mixed feelings with my dnail.
I love having an enail of my own around, but I constantly feel the unit is underperforming.
I am now dialed up to 740* on small less than rice grain size drops using the SiC.
Bubbles at first for a millisecond, then pools and just sits in the dish. Cannot get efficient vaporization.
The pooling will give light production for MANY pulls, but taste turns south after the first 2 or 3.
I Qtip every pull, I clean religiously. Coil is flat, everything in the system is wrenched tight as can be by hand. Should I really have to be cranking the temp dial all the way into the high 800s or even hotter just to achieve full vaporization? It just does not seem right when everyone else is in the high 500's with good success.
Taste is great on the SiC, but the cleaner in me does not like it. I have tried heat cleaning on the base, I have tried torch cleaning, and I have tried scrubbing the shit out of it with Iso toothpicks and qtips. I have accepted that this dish will never look and clean up like it was new. I like Quartz in that regard as it looks perfect for a red carpet after a cleaning.
According to the d-nail graph the coil should be at 675 to get the dish at to 600. I have a pid/coil from dhgate and I have to turn it up to around 755. To to the d-nail sapphire insert I have to turn it up almost 200 degrees higher than in the graph recommends. Having something to tell me the temp of the dish helped a lot, I'd recommend getting a thermometer with a thermocouple. I tried an ir gun first but the temp readings were waaaaaay off with it. It bugged me to buy it because I won't use it for anything else, but it's really nice knowing exactly what temp the dish is. I got this one for $22 off amazon.Mixed feelings with my dnail.

For me to get around 600 degrees on the sic dish for my tag I run at 725 and for my d-nail at 755. It's a bigger dish though so that makes sense I guess.Well, no luck in rolling the temp back down. Tried...heat sinked the crap out of it, but its just a simple fact that my SiC Halo just needs a higher coil temp than my Liger to get what appears to be equal dab surface temp. Makes sense, the Halo is exposed, the Liger insert is surrounded by Ti and has a greater amount of Ti to act as heat sink.
Just to make it clear, my Slimline Halo is assembled this manner:
View attachment 471
top Halo retaining nut
SiC Halo
Flat coil
Heater retaining nut
Heat sink
Base retaining nut
Base
D-nail carb cap and fork handle
All from D-nail and used with an Auber RDK-300
What I have found is that when I try to operate at about 650 F coil temp or below, yeah...I get a few nice hits, but can't really milk the rig (yeah, bb to rice grain size...I don't do globs) the way I do with the Liger at 580 or so.
Also, vapor quits at a point and there is quite a bit of oil reclaim to q-tip out.
At 675, I got milk...quite a differential from Liger coil temp of 585.
I know that many quite like to get multiple low temp draws off of a dab, but I'm more into a dab = one thick draw (with maybe a little clean up draw if you can stand the taste LOL).
To be clear, I agree completely with those who say that coil temp is inconsequential. Its the temp on the dab surface that counts and right now the only way I have to judge that is by comparison of vaporization performance at a given coil temp (but I am order a k-type thermo that will go high enough and I plan to determine real dab surface temps for both the Liger and the D-nail at given coil settings).
It makes some sense that the D-nail would need a higher input temp as the Halo is completely exposed to ambient air and should probably shed heat faster than the Liger whose insert is surrounded by a Ti bucket and supported by a larger heat sink of Ti (by the by, I really don't know why D-nail calls their body a heat sink and then puts fins on it...I should think a solid with less surface area per amount of mass would make a better heat sink, yeah?)
So, right now I'm running 65-685 on the D-nail.
Anybody care to share their coil temps that they are using for a SiC Halo (not an insert...that would be different).
Cheers
Thanks...yeah, I have found a pretty nice one for $30 and intend to use it to document dab surface temp on the Liger (at 585 F on the controller) and the D-nail Halo. Otherwise, I'm just guessing based on the way the dab boils off.For me to get around 600 degrees on the sic dish for my tag I run at 725 and for my d-nail at 755. It's a bigger dish though so that makes sense I guess.
Also like you said I think a thermometer with a k-type thermocouple on it to measure the dish temp is really worth it. I got one on amazon for $20 that's worked really well. You can tell exactly what temp it is and check for any uneven heating. It did bug me a little to buy it knowing I'd never use it for anything else though. Especially after buying an ir gun that ended up being useless.
I am down to 615 on my RDK-200 with the SiC Halo but it does pool a little if I run out of breathe and dont complete the longer hit and like you I tend to want to take 1 good big hit and maybe a mini hit to clear anything I may have left. These results were much easier at 625 and especially higher like the temp range you mention (650-685) but I sometimes struggle at lower temps like the 615 I have been riding for the past couple of weeks. I too wasted money on a IR gun since they dont read SIC correctly and I have a grilling thermo that goes up to 454 F and I have watched it climb all the way until the thermo stops working but I would like to get a thermo with thermocouple like Stormy linked the other day. I wish I could find one cheaper thoWell, no luck in rolling the temp back down.

You can't get an accurate reading with a temp gun, the target area is too small and the emmisivity is variable depending on how dirty the dish is.Would you all please post links to the temp guns you are using to gather dish temp?
I have tried two from home depot and both were way off...
Yup, this. K-type thermocouples that are designed for use at nail temps are a must!You can't get an accurate reading with a temp gun, the target area is too small and the emmisivity is variable depending on how dirty the dish is.
sooooo what the hell is k thermocouples? Can you post a link to a good one?Yup, this. K-type thermocouples that are designed for use at nail temps are a must!
Your measurements are only ever as reliable as your tools and their appropriateness for the task at hand.
https://en.wikipedia.org/wiki/Thermocouple#Type_Ksooooo what the hell is k thermocouples? Can you post a link to a good one?
I cannot post pics of my nail setup man, sorry. A k-type thermocouple is a metal probe that plugs into a digital multimeter. You touch the metal probe on the thing whose temp you want to measure, it tells you the reading on the multi-meter.I still don't understand how it works.
Is it just a pair of wires I put on opposite sides of the dish?
What else do I need to display the temp reading or do they plug into a CPU USB? What powers the couple?
How do I mount these if solder will melt at these temps?
Does thermocouple mount permanently?
Could you please post a pic of how it is all setup on your nail? I just see wires come up in searches but I have not found these details.
That is a tricky question, thermocouples can be bought individually from $5 (they can be much more expensive depending on specs). Multimeters can be bought for very widely varied prices from $10 upwards. You may need to spend slightly more than this. Beware that a lot of multimeters I've seen on amazon that say they are compatible with very high temps are misleading, because the thermocouple that is packaged and sold with the multimeter is not actually compatible with high temps, only the multi-meter is when used with compatible high temp thermocouples. This would mean that you would need to buy an additional thermocouple that will connect with your multimeter and be safe to measure the temps you seek to measure.That explains much! Thank you!
Last question for now... I promise
How much should one anticipate spending on a reliable couple?
I got one for $20 on amazon after first buying a useless ir gun and it's worked great so far. Ignore the dirty glass...I still don't understand how it works.

Uhhhhsssshhh....that would be difficult.I was hoping to score one for $10 or less
Forget the IR guns....the link I posted takes you to Amazon...pick the K-type thermocouple thermometer of your choice from about $20 and up. Be sure to check the temp range of the TC probe you get.Would you all please post links to the temp guns you are using to gather dish temp?

sooooo what the hell is k thermocouples?
But not impossible. I bought this one cause I like orange...hopefully the K type thermocouple is the correct one.Uhhhhsssshhh....that would be difficult.
