big shot max height

I would say the difference between mechanical release and hand is that a machine just can't replicate a human hand. I bet super slo-mo would show some sort of lag in the mechanical release.

I've tried different styles of release including the archery ones, which release completely clean. That's not it. I suspect it has to do with the angle of pull.

When you use a mechanical release the pouch is pulled back towards the base of the pole; when you pull with your hand you pull parallel to the pole. That is my best guess to explain this thing that I've seen in the field, but I certainly could be wrong.
 
I think with hand pulling there's a much shorter time between the extension and throw. With a trigger release people often keep it locked and loaded for longer than on a hand pull. This is just a guess but I believe there is some depreciation in tubing elasticity while it's being held extended. This is definitely true in cooler temps, dramatically so. Conversely if you heat latex tubing it becomes more effective for higher throws.

AJ, now there is something that would explain it, especially talking about it in the winter, I have seen you warm them up.
I agree too, when I wind it up I'm anxious to get the shot off. The trigger does give me a few extra moments to relax and squeeze the shot off accurately and because I can hold it like a shot gun I can sight down the barrel so to speak. The bullet shaped steel weight is dead accurate. PPE of course.

It is true that care must be used when using the length of line pulled from a throw line cube for determining shot hight. If a slightly arching shot is used it will pull much more line than the actual hight achieved. What I did was to shoot straight up with a premeasured length and observer. If the line that is tied to the storage cube tuggeds it off the ground I feel confident at having reached that hight.
 
Goes on Pole Kevin if using a MA. Without the MA along with the release the trigger probably doesn't make much sense although it could still be done.

Archer trigger you hold or put on pole?

I put it on the pole with a piece of string as a Prussik for grip.
Just slide it down the pole to gain the required power.
Better still, I got half a windsurf mast, rigged the trigger on a pulley system to make it easier to pull on tension.
Then put tape marks on the pole/mast as reference points.
 
Funny thing about trying to calibrate throw height when you're using a pulldown or trigger hold system, air temperature completely throws off any attempts to get repeatability for a given height. At 80° f. you can shoot the moon, at 30° f. good luck ;-)

Is using a ten or twelve foot pole scary? Have you measured your pull force and distance? At what ppint do you worry that you will breal it. Has anyone experimented with flat bands vs tubular. Flat I understand is faster but you have to keep them untwisted.

I got interested in the big shot via the APTA which I absolutely love. BUT then recently I was reading about sulferized rubber which was one of if not the most important discovis of the industrial revolution. Are lifestyle is totally and completely dependent on the rubber tree which is tearing up rainforests, and planted in toxic pesticieded monocultures. Not suprisingly it is also gravely threatened by a fungus. Our entire civilization is at risk. Gaskets, latex gloves, tires, condoms, hoses, tubes, rubber bands, and slingshots.


Anyway that brings me quite late to the party of using a slingshot for line placement. I may as well get with the technology, and use up some rubber straight from laos and fire away.

Has anyone tried making their own slingshot? The bigshot seems about as good and simple as you can get. Definitly not something that could be simplified on or really even improved on based off of what I have seen.

I got sucked into a rabbit hole of watching slingshot videos and there is a huge science of flat bands vs round, vs how song how much pull, and even the taper. I guess a taper can increase speeds by 30%.
Like anything the more you learn the more you learn you don't know
 
I used to use two six ft poles, and yes it was a bit hard to control. We have an eight ft now. It only helps every once in a while.

Tried to use it yesterday in ten degrees and it barely cleared sixty ft. Embarrassing.

Interesting about the rubber sourcing, thanks bing

For me, living in Montana, this is a huge problem with the Bigshot. The APTA is so much better in dealing with temperature change and as has been mentioned the Bigshot pulled back to the max can be a bit scary. The fact that I can use standard throw line and weights with the APTA to reach any hight I may need is a big added bonus. .
 
Yeah I lovehe apta. Although after my initial love affair with it, I have mostly gone back to hand tossing everything just because it is the simplest and very few trees are very difficult here.

Thanks for the tip on the bike pump Dave, That will make a difference.

In practicality terms the pump aspect of the APTA makes it a bit of a pain. I realized I could get in three throws for every one with the APTA which just about balances out as I am about three times more accurate with the apta than by hand.

I love all this stuff. Ballistics, slingshots, and I get to say it's work related. What other job can say that?
