A friend of mine (Eric from Boulder/Colorado) challenged me a while ago. He said "Make a precise slingshot instead of a powerful one!"

Well, I did. Here is the result:

Very ingenious and clearly it works, what range was the test firing at?

From about 7 Meters. Never knew I am shaking that much!

Now, I have to applaud that as genius.

I've seen the idea of lasers bolted to slingshots before, but this is the first one that can actually practically work, what with the whole issue of the various different angles the bands can be drawn out at.

It looks like it needs a little fine tuning (seems to be hitting a little high and left), but it's still wonderfully clever.

You often don't realise that kind of thing until you actually have an aim point to given you reference.

I'm a decent enough shot, but even so, I hadn't really realised how much I can wander until I'd started using telescopic scopes.
It's less jittery than you're dealing with, but equally, I'm not trying to hold strong elastic under tension.

For reference, the best way to observe the difference in aiming brought about by the forces needed to hold something under tension is to see the difference in accuracy between a longbow and a compound bow.
Does that thing kinda look like a big cat to you?

Yes, it needs a bit of tuning, but that can wait until I get a much brighter laser. Saw a vid about a laser diode "harvested" from a DVD burner, now that's a bright one! You can pop balloons with it and ignite matches.

This weak 2 dollar laser pointer is no good in daylight. But I just wanted proof of concept.

Great invention!

A laser sight on a gun means that you can shoot from any position as long as the dot is on the target when you pull the trigger.

I really like shooting from the hip.

JoergS;

Very unique sighting system for a sling shot.
Ever consider a safer green laser <5mw rather than dangerous high powered red one?

The green ones definitely work better in bright sun light.
Here is a link for a JG-016.

You may have to search JG-016 in Europe.

Now that is just brilliant.
I was kinda smirking to myself when the video started like...Yeah right...a laser on a slingshot ..that ain't gonna work..

:roll:

:oops:

Very smart!

DVD burner lasers are for sure very powerful! But mine had very poor longevity, I would look into other options as well.

I must say, This is possibly one of the best-executed design solutions I have seen. It looks normal. It works like a champion.

As for a better laser, I highly recommend a green laser pointer who's purpose is gun sighting. they have built in windage/elevation that will make tuning a breeze. Also, they have a nice little on/off pad that would work itself nicely into your design.s

Overall, Simply beautiful.

I must confess this is exactly what I was thinking when I pressed "play", but glad to have been proven wrong.

This is particularly evident with high magnification scopes, especially at longer ranges. It's disheartening at first but in the long run sets you to a higher standard and makes you a better shot.

Hello,

The Slingshot Channel has tested two commercial slingshots.

----------------------------------

It is one of the most beautiful slingshots that money can buy: The "Lucky Seven", made by Bellsofhythe from England.

It is truly gorgeous and well worth the money (costs about 100 UK pounds, altogether).

-------------------------------------

There has been a lot of hype around the Chinese made "Dankung" slingshots lately. The Slingshot Channel has received one of their larger, more expensive models, the "Warrior", and duly tested it.

I questioned it on seeing the topic title... but on seeing the youtube "thumbnail", I immediately knew what he'd done.

Indeed, it was somewhat depressing at first, but you learn over time what works and what doesn't.

With a strong scope, I think you learn that you need to pull the trigger at the right moment. Right when you shake through the bullseye!

I think the biathlon guys know how to do that. Imagine you got to hit with a heart rate of 160 beats per second, and a blood pressure that goes through the roof...

I can't quite get away with that, given that I shoot springers, which demand being a bit more controlled than just "vaguely when you wobble past the bullseye". (The fact they can't use bipods limits things a bit, too).
