I am selling my g-tech because I am looking to invest in a drift box. When the G-tech is properly calibrated, it is quite accurate. It is able to record 0-60, 0-100-0, 1/8 and 1/4 mile, lateral g's, and can store up to 30 different runs. It is in perfect condition and I bought it for $200. So please PM me with offers if you are interested.
