Air shox and poi

[justin davis]

Ok guys so I've seen a few guys say that air shox can change your poi. For example if you take them out ? Or in testing with a hooter shooter and moving the limb shox around they can get different poi.

Well I've had my bow dialed in and shooting well all summer long and into the fall. The other day I went out and shot when it was really cold out. I noticed that my poi was different. I thought it was just me or that day. A few days later it was warmer and I shot again and my poi was back on track.

Once again I shot on a real cold day and noticed a change in poi.

It left me scratching my head as to why the poi would change. Then I read a guy online say that he noticed a change in poi with his air shox in regards to temperature. This made me wonder if that's not what I'm seeing.

What do you guys think? Is it possible?

Justin. The case of the wandering zero......we all wish we knew the cause in every case. I'd do a freezer test with the bow and air shox, all on the same day if possible, (better than hoping for a cold snap). Repeat a time or two to see if you have any consistency between bow temps and POI.

Not air shox, but one that left me scratching my head for awhile.......last year was really wet most of the time on a Roosevelt elk hunt along the coast. My bow was shooting fine in the wet weather. When it dried out, it was shooting high??? Finally figured it out that the fabric on the launcher arm had come loose on the bottom side. It wrinkled and raised up in the launcher V when it dried out. I re-glued it down, problem solved, but something to keep an eye on in the future.

Yea I should do a freezer test. I'm really thinking it is thou. I've read before of guys using a hooter shooter to test poi relating to limb dampeners. They found that if they moved a bit then the poi could change.

I'm wondering with these air shox that if they move a little it could affect your poi.

I'm also thinking the cold maybe affects it too as the limb hits the rubber. Maybe if the rubber is colder it has a differnt reaction than warmer this causing different poi.

I'm tempted to hunt without the air shox. Seems like a variable that can affect accuracy that should be eliminated

I took them off my Element.

If they move it will absolutely change POI. Of equal importance is to use a string/cable assy with enough strands to mitigate shrink/stretch with temp changes. The target guys I shoot with are using cable assemblies with 32+ strands.

I took them off. I'm thinking about using nothing on the limbs.

I'm not really hearing a difference in sound with them off. I'm sure there is a difference but to my ears I'm not noticing a difference

Put an app to measure sound on your iphone. I use SPLnFFT and get noise level (dB) data on bow or arrow changes I make. I did a few checks against a $2,000 meter at work and the iPhone was right there. When shooting my bow I just set the phone on the ground, shoot 3 arrows while kneeling down then make the bow or arrow change and repeat. It gives me data instead of guessing. Cost was a few $ when I bought this app a couple years ago.

That's a good idea

The standard ones that come on the hoyts? I'd take them off, all they do is cause limbs to splinter.

Can you elaborate a little?

Look at all the Hoyt "finish" splinters on the limbs since 2013. All start at the air shox unless you've hit the limb sideways on something. The constant slapping of the rubber on the limbs, especially with that finish, will cause and cause the splinters.

Didn't Hoyt stop the air shox this year? You think it's a coincidence with all the limb splinters coming after the air shox and then they go away from it 3 years later? That's why I sold my 2013 spyder turbo. I'm not gonna by $300 limbs to learn the air shox sucked.

Gotcha. Yea I think they did away with them this year due to the new limbs. The air shox wouldn't work on the new limbs.

Yea I don't think the air shox are that great. Don't think they do much

+1 on this app. I've been using it this year on an iphone with great results. Very few people can reliably and repeatably differentiate bow noise levels.

 

[justin davis]

Ok I downloaded the app and did some sounds tests

With the
Air shox: 82.5 DB
Limb shox: 81 DB
Nothing: 83.5 DB

So the limb shox were the quietest. But there isn't much of a difference with nothing in the limbs!

I did a little experimenting with the air shox on my bow a while back. Had my bow shooting great through paper at multiple distances. Took off the air shox and added some Limbsavers dampers in their place. Took a perfect hole through paper to a high right tear. Replaced the shoxs and it was back to perfect again.

So any change to the air shox could most definitely change your poi in my opinion from my findings.

Yea I'm debating running the bow with nothing on the limbs. Touch louder but eliminates the variable to something moving and my poi changing. Interesting stuff.

I guess this means you will need to pick up a 2016 Hoyt Justin!

I didn't notice any differences with mine off. Truth be told I swapped strings on my Element and those stupid Limb Shox get in the way when trying to put a bow in a vice and get it level. I took the bottom one off when I was setting the bow back up because of the vice issue. About a month and a half later I was shooting one day and noticed I had never put it back on.

I put it back on and nothing changed or moved. Then I took them both off, again, on my bow, nothing changed or moved. I couldn't feel or hear any difference without them so I just left them off at that point. Two things carbon bows don't need are sound and vibration dampening devices.
