Tack Sprayer is a level 3 upgrade for the Tack Shooter on Path 1 in Bloons TD 5, costing $425 on Easy, $500 on Medium, $540 on Hard and $600 on Impoppable. Instead of 8 tacks shooting out, it shoots out 16 making it more powerful than before and pops more too. Since it shoots out 16 tacks it is almost impossible for bloons to dodge the tacks.
