Soo I just got a new line put in my spinning reel, 30lb braid spider wire

and today I did some semi fishing to try it out. So it worked and and to my liking just had one probably after several cast my line would tangle up as I'm casting it so I would have to stop to untangle it

it wasn't tangling in the reel, it was tangling as it went the  holes on the rod and I'm trying to figure out what it is

i took it to cabelas so they could spool it for me 

I tried to unspool bout 50 yards and spool it back up thinking the line wasn't tight 

someone please help or suggestion 

 

What size is the spinning reel and what is the rod you are using?

If, after you cast, there is some loose line at the spool and you start reeling, that loose line will leave a loop that sticks off the spool. On your next cast, the line coming off the spool will catch that extra loop and pull it off which causes the tangle you are talking about. Usually these are called wind knots. If you get in the habit of tugging on your line after you close the bail to get rid of the slack before you start reeling, you won't get the wind knot.

They may have spooled it wrong.  Even people that should know better spool bait casters and spinning reels the same.  Line twist does not matter as much with braid, but it does matter.  The loops that @Scott F mentioned will be worse if the line is installed wrong.  30 lb rarely has "wind knots" in my experience.  15 lb and down requires due diligence!  Watch your spool!  If you see a loop or loose line, pull it off before you cast again.

If you fish from a boat it's easy to untwist line by running the line behind the boat at walking speed. Cut off everything so the line only is in the water, about 50 yards and let run for about a few minutes, the water will untwist the line. While the boat is still  moving wind the line back onto the reel. 

follow the advice about manually engaging the spinning reel bail and the problem should be solved.
