It's a magma clone, and it came with two little pre-built pre-wicked coils. They look so small and the wire is so thin I expected it to read closer to .5 but it's really high... I have 28 gauge kanthal and some cotton on the way to build my own coils, they just aren't here yet and I got anxious to try my new setup. What do you think would cause the ohms to change? Btw, I don't have an ohm meter, I'm just reading the mod.
I would check those screws. If BOTH coils are attached, then that means that each individual coil would be 5 ohms apiece 
?
If it only has one 2.5 coil attached, then add the other to make the dual coils read at 1/2 the resistance (1.7)......

What Hdivr said.
Make sure the screws are tight on the coil leads or you'll have inconsistent readings. Once it's set, touch the coils to see if they move. If they do, reseat them. I'm gonna guess that you only used 1 coil at 2.5Ω. The rDNA is probably a more accurate ohm reader than most ohm readers.
If you're really stuck, try to find a vape shop that might help you. They might be able to build you a coil and teach you some tricks. A quick search shows a few shops SW of Detroit with good ratings.
Thanks for the suggestions, guys. I've tightened the screws now to the point where I'm afraid I'll cut the leads if I go any tighter, and the coil doesnt move when I touch it, but it still changes the reading every time I press the fire button. Anywhere from 2.42 to 2.86 now. And yes, I've only attached one of the coils. It isnt the resistance that bothers me, it's the varying reading. Could it be a mod-to-rda connection issue? Unfortunately this rda doesn't seem to have an adjustable 510, I hope I'm not just out of luck. The thing does fire though.
Thank you for the search, KTMRider, but I actually don't have the transportation to a vape shop in my near future, so I'm stuck trying to work this out with only teh internetz. :/

You shouldn't need an adjustable 510 on the rda, the rDNA has a spring loaded 510 pin.
Are you in TP mode? Click fire 5x, then press UP and DOWN until you see the temp setting. Scroll up until you get to 600°F and one more turns it off. Click fire 5x to unlock and try vaping (or fire) to see if it moves.

I suppose that functionally it doesn't affect anything, since it fires and all. I am just a bit worried that if my mod's ohm reader is malfunctioning for some reason, I may not be getting accurate readings on everything else. I've never vaped a vv mod before, or a dripper, but I'm surprised by how quickly 10w is burning my juice and drying my coil. I hope the wattage is accurate, and that it's an issue with the RDA (either by my own mistake or the maker's - I only paid $9.95 for the thing on eBay, after all). But supposedly the clone is made by sxk, which I believe own Infinite, so it's supposed to be a pretty good piece.
This is unfortunately my only atomizer that fits on a 510 mod.
I'll work on getting a picture.
I splurged. I got the black silicone sleeve. My rDNA30 black sleeve doesn't say Vaporshark on the side. I wish the mods were on more of a sale.

Bahhh... My camera can't focus well enough on something that small. I guess I'll just have to see what happens when I have what I know to be a1 kanthal and I put my own build on it. Perhaps the wire they used for this pre-built coil was made of subpar material and it doesn't transmit consistently? I don't know enough about electronics to know if that is even a thing.
I should have clarified, I am vaping at 6-8w now actually, because it doesn't give me dry/burnt hits, I just thought 10w seemed low to be too much. I have a lot to learn about the relationship between ohms, wattage, and voltage. I've been trying to get my head around it by reading for a while now, but I think some trial and error is the way to go.
If the resistance were lower, would that mean I could vape at a higher wattage without burning, because the voltage would be lower? I swear I'm not an idiot. This sort of brainwork is just not my forte; and unfortunately, neither is learning through Google searches.
Maybe this is a wicking issue as far as the dry hits. Some of the best advice I can give you is.........stop looking at the screen while you're vaping 
You'll drive yourself insane. Get a good coil mounted solid, a wick that wicks.....and is an enjoyable vape.

A dry hit is just not enough juice getting through the wick to the coil. To much wick doesn't let the juice get through fast enough for the draw. To little wick, well, pretty much the same thing.
Different toppers, to me, have to be used with slight differences. When I buy an RTA, I am generally expecting to get a second and they, then, go through the usage line-up together. Kinda keeps me sharp. When I build the first, I remember some innuendos. When I build the second, I may catch more and then will go back and rebuild the first. Seems to help.
I just did two KF4s last night and forgot that they seem sensitive to having to much/dense of a wick in comparison. I remembered it, but sometimes i don't.
Anyway, I rarely (very) get dry hits. I doubt that i will even go TC coiling for a good while. Cigs are zero maintenance, I am happy to raise the hood in the middle of the race and make a quick adjustment.
Tinkering is healthy and relaxing.
