1. Where can I purchase Firenock?
Firenock are only sold through Firenock-International's authorized distributors' retail dealers and channels.

How heavy is a Firenock?
Firenock v1.x - ~19 grains without the nock and ~31 grains with nock, ESBEC, and battery installed
Firenock v2.0s - ~ 25 grains with nock and battery installed
Firenock v2.0a - ~ 22 grains with nock and battery installed
Firenock v2.0e - ~ 23 grains with nock and battery installed
Firenock v2.0c - ~ 29 grains with nock and battery installed

What arrows will Firenock fit?
Firenock v2.0s will fit most standard carbon arrow shafts and also fit aluminum shafts that can utilize
the uni-bushing system; with an internal diameter of 0.242" - 0.246"
Firenock v2.0a will fit most narrow arrow shafts with an internal diameter of 0.202" - 0.204"
(i.e. Bemans™ MFX™, Easton™ Axis™, Carbon Express™ Edge™)
Firenock v2.0e will fit most medium arrow shafts with an internal diameter of 0.229" - 0.231"
(i.e. Easton™ A/C/C 3-49/390, ST Epic™, ST Epic Realtree HD Green™)
Firenock v2.0c will fit most crossbow bolt shafts with an internal diameter ID of 0.297" - 0.303"

What nock does Firenock use; they look different than any I know of?
In order to make the most versatile fitting and the best lighted nock, Firenock took the only way that would allow us to achieve these targets. That is we design and make our own nocks. This is the most expensive and complicated route to make a lighted nock. Every moulds of Firenock are designed with extreme tight tolerance (0.001 mm) and molded with the best polycarbonate for nock making based on our research. Based on published specifications, we know that it has a better IZOD respond to tackle issue like memory and shear force, we are also able to control how the optical characteristic of each nock will be.
To satisfy the toughest demand for matched nock for the most discrete target shooter, all production moulds of Firenock's nock have cavity number. This straight production rule allows us to provide matched nocks that will be within 0.000,001 mm and 0.1 grains variance (Available only in target pack (MSRP $750.00 which it contains 45 lighted nocks and 45 matched weight nocks).
From our test bench, we consistently get 1 to 2 ft per second faster results than most other manufacturer's nock (when shoot without the circuit board installed).
When you use Firenock; you not only get the lightest and brightest lighted nock on the market, you also get one of the best shooting nock too.

Will any Firenock fit Easton A/C/C 3-60/340 arrows?
Easton A/C/C 3-60/340 arrows have an internal diameter of 0.240" and since they are carbon wrap over aluminum, there is absolutely no give. Firenock v2.0s go as small as 0.242", BUT with some minor modification, they both will fit the Easton arrows. Use a razor blade and shave off 8 ridges on the nock cylinder. By doing so, you reduce the Outer Diameter (OD) of the nock to 0.2405" which would make a perfect contact with the ID of the arrow shaft and also with the right snug. Not out of the package easy, but it works like a charm.

6. Will any Firenock fit Easton A/C/C 3-49/390, 3-39/440 and 2-28/500 and Epic arrows?
After some serious testing. We concluded that Firenock 2.0e can fit all the above sizes: ACC/3-49/390 3-39/440 and 2-28/500 with no or very minor modifications.
A/C/C 3-49/390 has an inside diameter of 0.2305" or 5.86mm
A/C/C 3-39/440 has an inside diameter of 0.2175" or 5.54mm
A/C/C 2-28/500 has an inside diameter of 0.2085" or 5.16mm
Firenock 2.0e design is base on an oversized Firenock's 2.0a mould which has a cylinder of 0.2047". Now with the 12 ridges being 0.0129" high each, it can easily be shaved to fit (with the Uni-Bushing removed of course). We are in the process of developing the ideal way to do that resizing). This is what we have so far:
1) find an extra piece of the arrow tube that you are planning to use
2) cut it down to about 3" for ease of handling
3) grind the outside so you have a sharp edge on the ID of the tubing
4) place Firenock v2.0e in the nock tool with the nock cylinder pointing up
5) slightly tap the 3" shaving tube (the one you just made) on to the nock
6) some of the ridges will be shaved off as you force down the tube
7) do not shave the 30 degree wedge edge at the very end of the nock cylinder.
That part you still for perfect centering fit
Not off the package easy, but at least one now can get a lighted nock for the A/C/C 3-39/440 and 2-28/500.

Where Is Firenock made in?
Firenock is conceived and designed in USA. Firenock is assembled in China with components from (base on value of content in ascending order (USA, Mexico, Japan, Korea, Taiwan, Hong Kong, China, and others.)) USA parts content of Firenock v2.0s is 40% of the cost of the entire package. The heart and brain of Firenock is made in US by Motorola and 3 other US factories in California, New York, and Illinois. The market we live in dictate that we much provide the lowest cost possible to the consumer with the highest quality product. To achieve the best price and still maintain the highest quality, we have our product custom assembled and packed in China. If Firenock were assembled in US, it may cost as high as $97.95 for a pack due to overhead and labor cost.

What makes Firenock so different and claiming to be "The Most Advanced Lighted Nock"?
Firenock is not just some simple wire with LED, or re-assembled fishing bobber light in a nock.
To make "The Most Advanced Lighted Nock"; one must get best material and develop/locate the best process. Firenock specify 0.0001 mm polycarbonate capable molding steel form Germany, and the highest quality resin force injected to get the best IZOD and translucent property (We have to deal with optical quality of the polycarbonate too).
For the brain and sole of Firenock, we start with a 2-layer circuit board, utilizing 24K gold connectors solder at 90 degree to the board (a special process must be developed). SMT machines usually only deal with 2 axis, not 3 as we specify; thus a process have to be developed, and we did. Inside every Firenock, there is a 17G reed and a full Motorola chip set to drive the fuzzy logic circuit. After we try and fail to source Titanium alloy wire from central Europe. We now have a totally different alloy wire made in Japan, which meet the specification (handle shock of a 450fps cross bow when shot into a 2X4 without failure).
Firenock also have to design his own battery just to fit our need. With a shelf life of 100 months and epoxy coating, it is the only battery that we know of which can do self recharge up to 1/2 the discharge. No easy chemistry there, and to work form -40F to 60C it is even more challenging than we have experience. Lithium polymer, and oxides discharge is tough to balance.
In the case of the battery wire, robotics that allow do a cross and 360 band backwards to form the cross lock were developed. Traditional methods like, manual jigs forming/banding and most spring banding machine just will not handle it. Both processes above form micro crack on the 0.42 mm titanium alloy wire when forming. We uses a 4 axle and 2 arms system for making the battery wire now.
On the subject of the nocks, those alone have cost no less than 160+ engineering hours, and 8 moulds. For those in the know, you already know how expensive each 0.001 mm precision mould cost? Now add diamond patent on the ridges and do a 0.000,02" polish on the prongs to give Firenock the cleanest release possible. If that is not enough, there are mould and cavity number on each nock. With special attention, a set of nocks that is theoretically 0.000,009" as variance can be provided.
We at Firenock International understand that it is all very scientific and technical, but without that how can one approach the theatrically of 100%. As one can see, it is not easy, and definitely not cheap to do. Simple to use is a very expensive and involve process, not to mention it is usually the most difficult and advance approach. This is why we feel that it is very fitting to call Firenock "The Most Advanced Lighted Nock".

How long will the Firenock battery last?
For Firenock v1.x lighted nock systems, our test results showed that one should get 18 hours of continuous burn. If Firenock v1.x is lighted up at 1-hour increment at a time, one should expect 24 times 1-hour burn. (i.e. a fresh battery should last for a normal bow season).
For Firenock v2.0, our test results showed that the included new battery (new chemistry mix) will allow the light to be lit for no less than 24 hours and up to 48 times 1-hour burn.

What to do to fix the Extreme Shock Battery End Cap got stuck at the wrong depth while installing??
If you use fast set gels, you can use a screw that is deep enough to reach the battery end cap and then hammer it. This should loosen the battery end cap from the glue and allow you to reinstall the battery end cap at the correct depth again. If this does not work, install a new battery end cap in another arrow for convenience. You can also consider using slow set epoxy, which this would provide you more time to install the battery end cap, but the trade off is to add extra weight due to epoxy glue is heavy.

11. Where is the most ideal place to mount the actuator magnet?
Firenock's actuator magnet should be mounted on the arrow rest to get the best results. Ideally, you should have a place that is 2 inches from the board head/field point after full draw. That is about 7/16 of an inch away from the arrow path and is flat. In some situations, it is just too far for the actuator magnet to be 100% effective, and then you can consider adding a second magnet by stacking the second magnet on top of the first magnet, which this will make the distance 3/16 of an inch shorter. 1/8 of an inch is due to the height of the magnet, and the 1/16 of an inch is due to increase in magnetic force.
Firenock offers optional Actuator Brackets for Whisker Biscuit, Actuator Brackets for Trophy Taker and Actuator Magnet Pack (magnet in black color) for perfect actuator placement. See Accessories page for all accessories offer by Firenock to enhance your lighted nock system.

If I have to mount the Actuator on the riser, what should I watch out for?
Firenock's actuator magnet should be mounted on the arrow rest and not on the rise of the bow. That are two(2) major reasons for that:
1) Most newer bows' the distance from the riser to the center of the arrow exceed 3/4 of an inch, thus Firenock
in most cases do not work effectively.
2) With today's new drop away type arrow rest, most archer use shorter arrows as they use the drop away rest
like a mini-over draw. With that, the chance of the field tip/Boardhead being affected by the actuator magnet
and cause irregular arrow flight is high.
On paper due to liability, Firenock recommended no less than 2 inches from the actuator to the fieldtip/Broadhead when full draw to be safe. In real life situations, that totally depends on broad heads/field tips used. For people who use Titanium broad heads like Atom Titanium. It can be as close as 0" since there is no effect of magnetic force being felt since magnet have no effect on titanium. If high carbon steel material like what typical field points, or G5 Tekans are made of, a distance of 7/8" is about as close as you can get away with before it becomes a serious issue. Please note that the broad head starts with the screw and it is inside the shaft 3/4" to start with. That's said, the amounts of metal that affect by the actuator is a whole lot less in mass within the magnetic flux.
If one mounds the actuator off the side of the arrow path, then the distance will be more critical. If it is mounted at the exact top of the launch shelf, (right underneath the arrow) then one may get away with a lot more since it is just more force (magnetic force) besides the gravitation force affecting the arrow.
In cases of getting too close with the Actuator Magnet, one can expect to see as much as 10 inches off to your right at 20 yards shots with a right hand bow. This effect can be even more dramatically increase as one put some hand torque to the bow, for this action will bring the arrow that much closer to the Actuator Magnet.

Where do I put my Actuator Magnet, my rest was not shown on the Actuator Placement Page?
Please send us a picture and/or the link about the arrow rest in question. One of our field testers may have already had one and know the perfect place to place the actuator magnet. If so, once we have tested and confirm the result, a picture of the rest will be on the Actuator Placement page shortly.

I used my double sided tape in the wrong place, where do I get a new one?
The die cut 3M VHB double-sided tape is a one time use material. The cheapest way to get similar performance and spare is to get a roll of 3M outdoor double-sided tape. You can purchase it in your local Wal-mart store's paint section where the glue and tape is. It is in a roll which is red in color for the peel off tape and the tape itself is grey in color.

Why the Firenock becomes so tight to fit in my arrow shaft?
In some cases, the nock of Firenock v1.x can be very tight after inserting into the shaft. This may due to dirt and excessive glue inside the shaft and/or shaft diameter is really too small (below or close to 0.243"). Applying small amount of bow wax or vegetable oil on the nock before inserting should make the job easier.
This is no longer an issue with Firenock v2.0 as it is engineered to take a narrower arrow (0.242") compare to the v1.5x's (0.243") and there is no need for glue while installing Firenock v2.0s.

16. How do I fix as my nock got stuck midway during insertion?
When you are in such situation, the only way out is to use pliers to try to pull the nock out. You will damage the nock for sure. If the nock can be pulled out, you will only need to replace the plastic nock and insert the circuit board back in another nock. This time, you should apply small amount of wax or oil on the nock to prevent nock sticking inside the shaft.

What is Extreme Shock Battery End Cap (ESBEC)? Do I need it?
Under normal hunting situation, you will NOT need ESBEC. However like all engineered product, the battery wire connector has its limitations. The battery wire connector will allow one to shoot into 2X4, and most trees and soil without failure. If you hunt in areas full of rocks, shoot it into concrete walls, steel drums, do video dart screens shooting, etc. then you need ESBEC. From our field test: as long as the arrow is not sheltered and the glue holds the ESBEC in place, the system will not fail, Firenock with ESBEC installed will survive the extreme shock and will still remain lit. ESBEC with the O-ring weigh 3.4 grains.

Do I need Extreme Shock Battery End Cap (ESBEC) for video screen shooting?
Yes, you absolutely need Extreme Shock Battery End Cap (ESBEC) for video screen shooting. This activity is one of the most punishing of all things one can do to a lighted nock of this design. The constant pounding of the arrow to the screen and the dropping of the arrow to the floor will do all kinds of damages to the custom polycarbonate nock without the ESBEC installed. To protect and prevent the circuit board, nock and battery from being destroyed, install Extreme Shock Battery End Cap is the only way we know if you want to use your Firenock with video screen shooting. From our field tests: with ESBEC installed, the system will not fail, and will survive a few dart leagues without any doubt.

Did I get the wrong size as I cannot get the Extreme Shock Battery End Cap into the arrow shaft?
Without putting the O-ring on the battery end cap and then insert the battery end cap into the arrow shaft. If the battery end cap slides in without problem, it is fine and then applies glue to fix the position of the battery end cap. Try to insert the battery end cap with O-ring installed at an angle. With one end of the O-ring is in the shaft, push the O-ring with your fingernail, twist the shaft with another hand, the battery end cap should be inserted into the shaft.

My lighted nock does not light up?
Like all electronics, poor battery connection is the number one cause of not getting the lighted nock to work. Please check to make sure that the first cross lock of the battery wire connector is indeed seated tightly at the neck grove of the battery (refer to diagram of the installation diagram manual from the installation page for more details), and the cross lock battery wire connector is not touching the center battery pin. If this happens for extended period of time, you may have already shorted out the battery and a new battery is required.
If even with a new battery is installed properly the nock does not light up after passing the actuator, a drop test can be performed to see if the switch is just stuck. From a height of no less than 18 inches and no more than 6 feet, drop the nock onto a hard surface (concrete floor in your garage is a good hard surface to do this test). If the nock does not turn on, wait 10 seconds and try one more drop. After this test, if the nock still does not light up please check with your local dealer and distributor warranty arrangement.

21. My lighted nock does not shut off?
Firenock can need up to 8 seconds for the system to reset due to extreme temperature or humidity. Firenock also has a built in motion sensor for further shut off protection. i.e. Firenock will remain lit when it encounters shock, motion, and/or magnet field within the 4-8 seconds after it has been lit. Thus Firenock can be reset or turned off after the 4-8 seconds delay.
For testing, please hold the lighted nock motionless and wait 10 seconds, then pass the lighted nock over the actuator magnet. If light still does not turn off after passing the actuator, a drop test can be performed to see if the switch on the circuit board is just stuck. From a height of no less than 18 inches and no more than 6 feet, drop the nock onto a hard surface (concrete floor in your garage is good hard surface to do this test). If the nock does not turn off, wait 10 seconds and try one more drop. After this test, if the nock still does not turn off and the nock is within the warranty period, please send it back to us for replacement.

My lighted nock is working fine and now it shut off upon impact, what to do?
Firenock uses a battery that have an aluminum shell which it is the positive end of the battery. The battery wire connector needs to make constant contact with the shell in order to let the system operate properly. What you observed can happen in cases when the battery is not installed properly, as in:
1) Dirt or oil was deposited on the shell of the battery during installation
2) The "C" lock at the end of battery wire connector was bent open, thus it is too loose
3) The battery wire was not cross locked properly
For situations described above, they all were caused by the battery wire connector not making full contact with the battery, and this is an easy fix. Remove the battery and reinstall it again. In situation (2), please press close the "C" lock a bit with your finger, so it grabs the battery tighter, then all will be fine again. If the nock still does not work properly please check with your local dealer and distributor warranty arrangement.

Will there be a better Firenock soon?
Firenock on this web pages are the lightest and fastest that Firenock has ever made. You can most assure when we can market a better Firenock, you will see it on this web site.
