Cobra BiO Cell, BiO Cell+ irons

Like the woods and hybrids that Cobra Golf recently introduced in the BiO Cell family, the BiO Cell and BiO Cell+ irons were designed to create more ball speed for a wide range of players and deliver plenty of forgiveness.

Cobra engineers gave the BiO Cell irons a deep undercut behind the hitting area that shifts weight back, away from the face. This creates a hitting area that is unsupported and free to flex more effectively at impact, which Cobra says should provide players with more ball speed and more distance. The company says that the BiO Cell irons have the largest unsupported face of any irons it has produced.

The face has been designed to be thicker in the center and thinner around the perimeter, but not symmetrically. For the past four seasons Cobra has made driver faces that are optimized to help golfers compensate for their most common mis-hits, low in the heel and high in the toe, and now that philosophy has been brought to irons too. Cobra says that it not only will help golfers maintain ball speed on off-center hits, but the use of "e9 Face Technology" also creates discretionary weight that can be moved elsewhere to enhance performance.

A four-pocketed structure is designed into the back of the irons. In the long and mid irons, the chambers closest to the heel and the toe are filled with tungsten to increase MOI and make the clubs more resistant to twisting on off-center hits. In the short irons those chambers are open, but the two center chambers are filled with tungsten to put more weight directly behind the ball at impact to enhance feel.

"While the two irons, the BiO Cell and the BiO Cell+, look alike, they're very different," said Jose Miraflor, Cobra Puma Golf's director of product marketing. "They both feature the undercut design, but it's deeper in the BiO Cell. The BiO Cell+ iron features an undercut that is not quite as deep, because we wanted to bring the (center of gravity) a little higher so the player could get a little more trajectory control."

Miraflor also noted that the BiO Cell+ irons are slightly smaller than the standard BiO Cell irons.

"If you're a golfer that is looking for forgiveness and distance, the BiO Cell irons should be your choice," Miraflor said. "If you're someone who wants some forgiveness and some distance, but are really looking for control in the form of a compact shape and a low-offset look, the BiO Cell+ irons are the irons for you."

Cobra has offered golfers more style options that any company over the past two seasons, and that trend continues with the BiO Cell irons. Both sets are available with black, blue, orange or red accents.

The BiO Cell irons are $699 with True Temper Dynalite 85 shafts. Graphite shafts are available through custom order for $104 per club. The BiO Cell+ irons are $799 with True Temper Dynamic Gold S300 shafts.
