Fixed power scope vs speed adjustable

I would like to hear some thoughts about advantages/disadvantages of each type scope. I have only shot fixed power and it seems the speed adjustable scopes would be the way to go. Are there disadvantages to speed adjustable scopes other than the speed and zoom are the same? If the zoom is changed and then returned to the correct speed setting are the yardages sometime incorrect? Is a good quality fixed power the way to go if I only want to hunt out to 60 yards? Thanks in advance for your opinions.

We had 5 speed adjustable scopes at one time. I can sell you one if you like. All new and unused.
My wife JOAD shooter, state champion and staff writer/shooter for savage arms hates them.
I find them crap as well. It's just hard to throw something in the garbage, that you paid for or got for free.
Seriously... Hit me up. CHEAP!!

A speed ring is not something you have "dink" with when the shot presents itself. You set it to the crossbow's advertised speed, dial it in at 20 yards, fine tune it at 40 yards with the speed ring and forget it. Once you get it set, it works essentially like a fixed power scope because you after that there's no need to touch the speed/power adjustment unless you change to a different weight arrow.

Speed rings let you adjust for the arrow trajectory when changing the weight of your arrows or changing your bow. When arrow trajectory changes, the speed ring can be adjusted to compensate. You can't do thsat with a fixed power.

All said, the speed ring is nice though. With it you can essentially get your scope hitting on all even yardages whereas with fixed it is where it is. This means with a variable scope you can get your crosshairs zero at 20, 30, 40 , etc. yards but with fixed it may fall out at 20, then 28, then 36, then 45, etc.

Not sure but Lever Action could be referring to the lenses in a variable scope “getting a snitch out of alignment/focus” as they traverse back and forth during different magnifications - not as a speed ring to sync different crossbow trajectories .

The lenses in a fixed scope stay “planted” in place much better, not sure about moving lens assemblies.

Another thing with variable scopes is the variable eye relief - if you have an exact cheek weld that you like this could mess with you somewhat.

I like my XB30 adjustable.

Got it dialed in so that I know each mark is at exactly 20, 30, 40, 50, 60, and 70 yds. There might be more marks than that on it, I don't remember because I never shoot past 50.

I would not want to have to figure out and then remember the exact yardage of each mark on a fixed scope.​
