Daystate T2 compressor

Excellent choice. You'll have to put the plug on the power cord, insert the filter, and put oil in the compressor. 

I also ran a drain line from the water separator to a plastic dish lined with paper towel and used duct tape to hold the line flat in the dish. I surrounded the line with paper towels so i have never had any splash or water to wipe off of the compressor.

I did use a few zip ties to hold the line place, because even opening the drain, even slowly could blow the line off of the drain spout.

So far the drain is working perfectly, no water to clean up.

Then you'll be filling your scba from 2800 to 4200 in 4 or 5 minutes.

I've also filled my two scuba tanks, 80 and a 117, both rated at 3442 psi, keep them filled and they take a few minutes also to top off.

Shoot all you want, you'll always have plenty of air in a few minutes.

 
The price was essentially the same, maybe about $25-50 extra. I just decided that if I were getting a Coltri anyway, I might as well get the Coltri-branded one. Maybe there will be a better support network, parts availability, etc., who knows. And if and when it comes time to sell it, maybe my potential buyers will include scuba divers as well air gunners. All guesses, but I'm satisfied with the purchase.

JFYI, the form factor is like the Daystate T1 not the T2, but I added the hour meter and auto-shutdown like on the T2.
 
When you get the compressor you'll have to add oil from the liter bottle.

Remember to remove the air cap next to the oil filler and add the oil slowly pausing a few times so you don't overfill, midway up the stick. I think it took about half a liter, this is all in the book. Then re place air cap. And snug down (push in) the filler cap. 

I always check the oil before each use. 

Youll LL also insert the filter cartridge in the filter tube. 

This compressor will change your approach to air gunning. No pressure to conserve etc, shoot in the sweet spot every time, shoot when where and how much you want. Hope you got pellets.
