I've got a pair of 10X50, & a pair of 8X42.
Both are Bushnell Perma-Focus (I hate to mess with adjustments).
So, IMHO, they would be a step or two up from your Tasco.
Both are very clear & work well, even in lower-light conditions of dawn/dusk.
The FOV for the 10X is 396ft @ 1000yds.
FOV for the 8X is 341ft @ 1000yds.
And both are parallax free up to about 50ft.
I know, a lot of people don't like Bushies, but for the cost, they normally are pretty good stuff, IMO.
