rangefinding bowsites

[mixedbag]

I noticed an ad for drop dead bowsite ranging yesterday and was wondering if anyone has tried it.Seems like it could work within reason.Basically judges the size of say and elk at distances so you know which pin to use.They are only $25 and you add them to your existing site.Hoping someone on here may have some feedback about them.Sure would be alot easier then using a rangefinder

Sounds interesting, but I would not be able to use such a device on my bow in my current state.

it's not electronic

For 20 bucks I might give it a go. Would have to test on some full size 3d targets before i trust the thing. I've gotten pretty good ranging out to 60 though.
