These look more like Terra ED than Conquest HD or Maven. The specs are almost identical:
8x42 Terra ED
Differences are in close focus (Terra focuses closer) and diopter adjustment (Terra's better here, too, only -+2 diopter adjustment for the Tract, which won't suit some users).
Same focus wheel as the 8x32 Terra ED, but hopefully with more stiction and not as fast as the 8x42 TED's focuser. I don't think the Terras have metal eyecup shafts under the eyecups like the Tract (not sure, somebody check theirs), if not, that's an improvement. OTOH, the $300 Vixen Foresta has a "full metal jacket" under the eyecups, too.
The Terras costs half the price, so unless the Tracts just look similar and have very similar specs to the Terra, but are optically on par with the Conquest HD or Maven, they are not a bargain even though sold direct. I'd like to see a Tract/Terra/Conquest A/B/C comparison.
I have a sneaky suspicion that other than alpha and second tier companies, which claim to make their bins from the ground up, there are at most a dozen roof prism bins in the world, maybe less, and that they are "cloned," given new "faces" and names but underneath are basically all the same bins either coming out of Japan or China. "Cloning," it's no longer just for sheep.
