Efficiency

[BowTrout]

Ok so I have a pretty dumb question. How much efficiency and energy is lost when string walking or shooting with a fixed crawl? Have you guys noticed a difference, is it a fair amount or is it minimal?

I tried a fixed crawl on one setup a couple years ago….long crawl of 7/8”, and I had to adjust the tune as my bareshafts were showing stiff.
I never chrono’d it but it had to be slightly less efficient.

My bet; short crawls of 1/4” or so won’t affect you much

Not much at all. I’m a 25.5-26 inch draw. My bare shaft stays the same on my stalker coyote with a a small crawl, prolly less then 1/2 an inch and takes my point in from 40 down to 25. I’ve killed a couple dozen critters the fixed crawl, it’s deadly. Adds a slight bit of noise but nothing drastic.

I went to a short crawl last year, right at 1/4" and I didnt have any flight issues.

Thinking about this;
You didn't mention the bow.

If it's a longer bow....a crawl has less of an effect. So for example, even with my 30.5" DL, if I was shooting a 68" bow...versus say a 58" bow...it will make a HUGE difference on efficiency- heck, it might not even work to crawl much on a short bow.

I used to shoot a 72" longbow a fellow lefty let me borrow to play around with and that bow was a dream to stringwalk on.

This is a 58” bow and about 26”DL. It seems to be working for me…. Depending on the day

You’re fine at that length. I also have an 26 inch draw. I’ve used a crawl on 54 inch toelke pika and similar recurves just fine. The longer the length the easier is it as mentioned but with such a short draw length it doesn’t effect it as much.

Well there you go.

I'm at the opposite end of the spectrum with a longer DL.....

“It depends.”

Bow length, tiller, finger width, release, how much crawl….

So, “some.” The question is are you more accurate?

Yeah I feel more accurate and have more confidence

Efficiency wise, its been proven time after time that you don’t need much energy to pound a 2 blade BH through a critter.

Assuming you use an efficient BH, the minuscule loss of energy from the crawl is a non issue.
