count down and up timer
This is a good frame to buy if your looking to go electro you can find it cheap in places got mine for 106 bucks at Action Sports Paintball in Cheboygan. It is really easy to use i get took it out of box and put it on my gun and plugged in the battery and it worked great. Also the LCD display is really easy to use. If you do get this i recommend that you get nitro if your running co2 because if you shoot full auto to long it could freeze up your gun. I would also recommend getting a version 3.1 or higher because all the others don't have much stuff for them.
I recommend you get this product if your a serious player. It maybe a little expensive but its worth the money. The only problem is keeping 9v on your hand thats the money getter.
