    Coilmaster 521 Mini Deal

    It sounds like the 510 threads are oxidized or there is a bad internal connection. Sent from my iPhone using Tapatalk

    Vaporesso Polar

    Really odd. It could possibly be a faulty connection. It doesn’t take much to throw off the calibration in SS. Make sure the terminal screws are tight and the tank is screwed on tight. Also the TCR for SS on the Polar Track the temperature most accurate at 84 instead of 92. Glad it started...

    Why did NiFe 52 disappear?

    That’s one, but Coil Society has a better selection.

    Why did NiFe 52 disappear?

    Yeah it seems to be more available in Europe. I’ve been all SS for a couple years since it’s easy to get, but I found a place I want to order some NiFe 70 from.

    Coilmaster 521 Mini Deal

    Very nice to work on and no need to remove the deck until it’s done. The eLeaf was like building on a matchbox. lol

    Coilmaster 521 Mini Deal

    Tried out the Coil Master 521 Mini V2 today to build a Troll RTA. This is much better! The ohm reading is spot on and being able to fire the coils is very nice.

    Building RTAs for years, I’ve been putting a method together for easy wicking of any of them. It’s very scientific. lol

    When something is difficult I analyze it and change/invent steps until it’s not difficult.

    Not sure if I should buy 10 or 20 Amp batteries?!

    I’d go with 15A cells. It’ll give you plenty of headroom at your power level and you can get higher mAH cells. Sent from my iPhone using Tapatalk

    Beginner MTL coil buid.

    Its been awhile since I’ve done MTL, but if I were to setup for that and I do primarily TC vape, I would get a Vandy Vape Berserker MTL RTA. As for coils I used a 2mm coil of 5 wraps of twisted 28g stainless. The thing to remember is that stainless measures a lot less than Kanthal in ohms, but...

    Why did NiFe 52 disappear?

    About 3 years back I was fond of NiFe 52 until it disappeared. When I got into using the now ubiquitous SS316L, I noticed that I had to make all electrical connections cleaner and tighter and have the mod set the resistance more accurately. The high TCR of NiFe 52 was not so finicky and not as...

    The Best Bottom Airflow / Dual RTA, You Can Recommend

    My current favorite dual coil RTA is the Wotofo Troll. Trouble free. Wicks great. 5ml of juice in a compact size. Not noisy. Very good flavor and vapor volume. Not for single coil though. I’m using 3mm 5 wrap 28/32 clapton coils. Sent from my iPhone using Tapatalk

    Coilmaster 521 Mini Deal

    Yup. That’s the one. I used contact cleaner under the power switch a couple years back when it stopped working. This 521 Mini will be a nice upgrade for $9. The eLeaf has more than run its course. lol

    Coilmaster 521 Mini Deal

    I saw it at LV for $9 and snagged it. I put up with the old eLeaf thing for far too long. lol

    Coilmaster 521 Mini Deal

    Came across this at 50% off at Lightning Vapes. Any of these good ohm readers are hard to find or discontinued and I’m wary of the clones I’ve come across. Sale ends at Midnight est. I’ve been using the cheap eleaf for years and it’s getting sketchy. lol

    Vaporesso Polar

    On using the Vaporesso SS ceramic coils and 0.00092 not being the right coefficient it just occurred to me that they must be using SS304 wire which has a coefficient of 0.00105. This explains why the default SS TCR is set at 110 which is exactly right for SS304. SS316L being so ubiquitous I just...

    What would be for you the minimum equipment?

    Just a couple Troll RTAs and a my Polar mod.

    Vaporesso Polar

    You’re welcome. :-) The wattage just sets how fast it ramps up, but it folds back as soon as it’s at the set temperature. Yeah, 230° is a comfy temperature and not beyond the flavor zone. Testing mods and tanks I’ve ODed on the nicotine more than once. I gotta get more 0 nicotine for doing...

    Vaporesso Polar

    Oddly enough their nickel ceramic coils worked not far above the standard nickel TCR setting.

    Vaporesso Polar

    Ooh that reminds me! Their ceramic coils don’t work the same as normal coils do! So yes it’s running way too cool. Back when I used them the default 110 TCR setting is closer to correct. They’re odd that way. My Target Pro liked it at 112. Where it’s relatively right is where 200°C feels pretty...
