50-60 yds is a stretch for even a seasoned bow hunter.

For me it would depend on how the deer react as far as ducking the arrow for archery hunting on the place you hunt. I have a 10 yr old Excalibur that is loud compared to todays crossbows. I would not even attempt a shot over 30 yards at a Texas deer. I had buck that I new was going to jump the string by his action in trail cam pics at feeders. I told myself I would not shoot at him unless he was 25 yards or less with my crossbow. I watched him for almost 4 weeks till he stepped inside of 25 yards. I aimed top of the heart and he still ducked 3" on impact. I am sure that the Raven is much faster and quieter but still 50-60 yards might be pushing it on Texas deer IME. You might have to teach aim lower than normal if your deer jump the string.

Crossbows are a very mechanical thing.

Raven are fast small bows but only offering a 5 year limited warranty throws me off from them more so than some of the others. Many crossbow makers only have 5 year as well. Centerpoint (which owns Ravin), Barnett and most others not listed below. Of course lifetime warranty means nothing if the company goes out of business like Parker. I have a parker that I bought when crossbows became legal in Texas so it has been a while, good bow not fast by todays standards but never had a hick up with it.

Tenpoint, Excalibur and Mathews/Mission have lifetime warranties. Toughest xbows out there are the Excalibur, being a recurve it will take more draw weight to reach speeds that the compounds do and unless you are quite strong forget the 400fps ones from them or expect to use their cocking device. Recurve bow you are all the way back before reaching peak draw. Their Micro series are more forgiving in that since they have a shorter draw so better mechanics for most when drawing. Reduced size and weight are handy as well.

Accuracy they can be pretty dang good. You will find though different bolts from the some package might just have different points of impact than others. I will mark my most accurate bolts for hunting use for the best shot possible.

With my 330fps Parker arrows it likes hitting 2.5 inch dots at 70 yards from a rest is no problem. I have killed hogs that far and a few yards beyond but they do not tend to react to the noise like most deer seem to. Deer after shooting a few I will not shoot one with my bow beyond 30 yards. Had a nice 10pt drop down and the arrow sai right over him at 40 yards and that was aiming for the heart. Had a doe take one step at 40 yards that went from being a good looking lung shot to getting the back of one lung and a bit of liver and she went well over 350 yards.

I bought the Wife a crossbow a few years ago Wicked Ridge RDX. The RDX design the bow is mounted reverse from most and puts the balance point between the hands like s rifle and she handles it much better than the weight being out front.

Rests, like others have said for a small person one of the clamp in tripods or I sold a Parker youth Challenger back when they were made with a cauldwell chair with the rest built on and swiveled to go in the ground blind to a couple kids Grandpa along with a popup blind. About a month later he came by with pics of the kids with their deer they had taken. Kids were 6 and 7 years old.

Go to some of the places you can handle and shoot crossbows to make your decision on the bow and somewhere the kids could also shoot it.

Just be sure to always keep your fingers down on the stock and not let them get in the string path the the string can cut the end of a finger off. Make sure the kids do as well

Excalibur has gone a long way in reducing noise of their bows with limb dampening devices which gets them down to about the same as many compound crossbows, but it does come at the cost of higher price.

I have a raven R500. I will promise you a deer is not ducking it at 80 yards. Wind isn't effecting it either.

Poker, I dont know you and dont aim to offend you, but a PROMISE is a strong word. Can you offer an explanation of what information you used to make that claim? The only thing I can think of that would come close to convincing me would be a large sample size of video shots that clearly showed the deer not ducking. I assume at great enough distances there comes a point where they cannot hear the shot, so theres that.
