What I know about archery isn't much, but I don't think it has to be super complicated.
We bought my grandson a Bear First Shot kit. It's got a little fiberglass bow and is intended for kids 4-7 years old. He just turned 6, so this should be OK for him to use (size and draw weight).
The only complaint that I see consistently is about the arrows.
"On the negative side, the arrows that come with it stink. I used some of the arrows from my own bow with it and it is much better. The small arrows that come with it are unbalanced and tend to fly all over when shot. This could be very frustrating for a new shooter so I would suggest looking for some better arrows."
"you CANNOT shoot vanes off a shelf"
"The issue is the plastic vains on the arrows cause the arrows to come off the shelf/handle sideways. So tomrrow I will go to my archery shop amd see if they can put feather fletches on those arrows."
But I wouldn't know what sort of arrows to get for a bow like this. Would bear really sell junk arrows with a kit like this? I've also seen some folks talking about modifications to shelves to help with this (in general, not necessarily for this bow). Should I get different arrows or go with what came with the bow?
How do I know where to put the finger rollers since there isn't a nocking point on the string? SHould I eyeball it? Should I use a square and set it just a hair above the level of the shelf?
I'd like to give my grandson the best chance to have fun, so any pointers or tip would be greatly appreciated.
