Tourspecgolfer recently took more pics of some of the other Geotech irons including from top to bottom:

The GT Gravity Control iron, these are soft SUS304 steel with two adjustable weight ports, one on the back heel and one on the toe. With these irons being geared towards 0-15 handicappers looking for some adjustability, they actually have reasonably low offset.

GT Forged Mid Hollow Cavity Back. An intersting design with an forged S25C face and neck matched with a SUS body for strength. The mid area between the forged face and steel body is hollow for forgiveness and distance. The forged face is thinner at the top and becomes thicker towards the bottom of the iron creating a soft feel on impact. Made for all levels.

GT Titanium Face irons are made for mid to high handicappers looking for distance and extra forgiveness. The 6-4 titanium face coupled with an undercut SUS630 body provides feel and hot ball speeds resulting in a super large sweetspot. A wide sole and adequete offset really help the improving player make solid contact.

Gocchin thanks for the pics!!! Cheers! I have always interested in GT's products, as my pockets aren't deep. (more importantly, I am still a learner)
