The G2 and Gold Bug Pro can usually be operated at full gain in an urban environment but I have to keep the T2 reduced to somewhere in the 70-85 range. The G2, with the 11" DD coil, seems to lock on the VDI better on some deeper targets that it will respond to than the T2, however, even though the T2 doesn't lock-on quite as well, the T2 gets better overall depth than the G2 or Gold Bug Pro when they are all using their 11" coils.
I haven't used the F-75 LDT, but I figure that it, or the T2 SE, would be the better units to use if you are using the Boost process and working in taller grasses and weeds.
I know I'll be hunting in taller grass and weeds at some of my favorite ghost towns in a few days. I will be away from the computer after today as I am headed to Idaho and maybe Utah to see my ailing brother, then call on some dealers and work in some detecting time. I'll be back on-line about the 2nd or 3rd. This time of year I know I can expect some taller grasses and brush in those desert town sites. Still, I'll use the smaller coils to work in and around some of the sage brush, but the taller grass will call for the larger coil.
I don't have the T2 SE, but I'll be the standard T2 w/11" DD will work out better for depth than the G2 w/11" DD. I'll know in a couple of weeks, but so far that has been the case from hunting brushy logging towns in the western Oregon coast range. I'll compare the 11" on the G2, but most of the time it will sport the 5" DD and I'll leave the 11' DD on the T2.
