A great competitive advantage in bowling today is modern urethane.  It provides bowlers with control and the ability to play different parts of the lane than reactive resin.  However, because urethane also has clear weaknesses, MOTIV® set out to create the ultimate cover material that harnesses the strengths of traditional urethane, but offers far more versatility. Introducing the Covert Tank. 

The revolutionary Frixion™ cover material MOTIV® developed for the Covert Tank is not urethane nor reactive resin. It is microcell polymer. Traditional urethane is virtually non-absorbing while reactive resin is highly absorbent.  Frixion™ microcell polymer absorbs oil at a fraction of the speed of reactive resin, but is still capable of absorbing oil at a very slow rate.  This microscopic difference creates more continuation and better pin carry without sacrificing traction. 

While typical urethane balls are primarily used by bowlers with a high rev rate, the Covert Tank is a more versatile piece that will benefit more styles of play because it merges this new microcell polymer cover with a strong Torx™ weight block.  The higher differential produces more track flare, which both improves backend motion and also limits oil redistribution.  Traditional urethane balls tend to have lower track flare, struggle with pin carry, and push more oil down lane.

Even the color scheme of the Covert Tank was created with the competitive bowler in mind.  The solid black cover with dark gray pearl NeoMark graphics provides a crisp contrast to the lane surface so ball motion is easy to see.

    Insane ball

    I tried the Covert Tank, and I never played like this before. This ball is insane.

    This ball is unreal!

    This ball does so much I really don't know where to start. I am able to use this on fresh, or with carry down when my pearls are skidding through the break point.. I need the predictability of this ball and I have never been able to throw Urethane due to my lower rev rate. This ball and its innovative coverstock are exactly what I need and I know I can rely on it when conditions are difficult.

    Covert Tank

    The Covert Tank is my favorite ball. This ball gives me the same motion as a Urethane ball, but it hits like a resin ball. It is smooth throughout the whole lane and for me never overreacts. I never leave home without this ball in my bag. Recently I shot 813 with this ball and moved a total of 3 boards all night, I love this ball!

    Covert Tank

    This ball is lethal! I can use it on a fresh house pattern, or a couple games in on a heavier oil pattern and still get the absolute most out of the ball. 10/10 recommend for anyone looking for a new ball for the arsenal.

    Great ball.

    I love this ball because I struggle with early rolling equipment and this I put a north star layout on and it lets me do a lot with it. When nothing is working and the shot is weird I can go to this and I can play straight or I can go left and swing it and it will carry like crazy. This ball has helped me bring my average up tremendously. Love it!!!
