Well no one seems to no the answer, so I went ahead and bought the 6T. The weight, backlight, weather resistant( not h2o proof), and notch feature when I want it, persuaded me to take a look. My dealer said the 6T has been doing very well in NW Arkansas dirt from coins to old farm relics. I also bought the prizm shooter DD coil, which I suspect I will like very much. Good hunting to all.
