I'd like to help both you and me here. I suggest a double-offset 6 inch HT or other high quality, unless you are fishing deep water (beyond 70 feet), in which case I'd say power auger may be better.
For shallow, (i fish mostly panfish) I suggest a hand auger, as (and here's where I'm greedy, for my own personal needs)... as you will reduce noise, and spook less fish.
I've watched some big panfish book it, and be gone for the day, right past me, spooked, and no longer interested in eating, because someone fired up a P.A. right nearby...
As well, with a good, new bladed
double offset handled hand auger, I can win a race with a power auger, hands down...
Well, that's all I've got.
p.s. I would not recommend the 4-inch version, for actually fishing out of, I have a 4-inch for my sounder, but never, ever stick a line down there... (a 15 plus crappie does not fit through it without 'ramming', followed by some swearing, and maybe crying.
"Eventually, all things merge into one, and a river runs through it. The river was cut by the world's great flood and runs over the rocks from the basement of time. On some of the rocks are timeless raindrops. Under the rocks are the words, and some of the words are theirs. I am haunted by waters"... N. Maclean.
"So let us then be up and doing
With a heart for any fate.
Still Achieving, Still Persuing,
Learn to Labour and to Wait".
