You may have heard other bowhunters talk about the “FOC” of their hunting arrows. (Who knows, you may have even heard “The Ranch Fairy” ranting about high FOC).

But, what does “FOC” mean and how can you easily calculate it?

What does FOC stand for?

“FOC” stands for Front-Of-Center (Or Forward-Of-Center) and refers to the percentage of an arrow’s overall weight that is forward of the balancing point, or, “center” of the arrow.




How to calculate FOC using a formula

You might like the FOC calculator but also want to learn how to calculate FOC using a formula.

The formula to calculate an arrow’s FOC is:

100 x (Balance Point measurement [A] – Arrow Length [L]) / 2.

To use this formula, you will first need to measure the arrow’s overall length as well as finding the balance point measurement.

Once you have found the arrow length (A) and balance point (B) measurements, use the formula above to find the FOC of your hunting arrow.

Finding the arrow’s length

To find your arrow’s length for the purposes of calculating FOC, you need to be sure you measure correctly.

Measure your arrow from the end of the arrow (where the broadhead/point screws in) to the bottom of the throat of the nock (see diagram above).

Once you have your arrow length measurement, you need to measure the balancing point…

How to find the “balance point” of an arrow

To find the balance point of your hunting arrow, first be sure you have already installed your nocks, vanes, inserts and broadheads/points onto your arrow.

balance point FOC diagram
To calculate FOC, you first need to find the “balance point” of your hunting arrow.


Using a triangular block of wood, find the exact place that your arrow balances perfectly. (If you don’t have a triangular block, you can also balance the arrow on your finger).

Once you have found the balance point of your arrow, measure from that point to the throat of your nock. This will be your balance point measurement.




Conclusion

Once you have measured your arrow’s length and balancing point, you can use the formula provided in the diagram above to calculate the FOC of your arrow.

Certainly bowhunters want to be the best they can be so that they can get an ethical kill. But, when it comes to FOC, there are varying opinions on whether higher or lower FOC is better.

Some bowhunters want a lighter overall arrow weight, so that the arrow is as fast as possible. The intent is often to keep the deer or other game from “ducking the string.”

The desire for a lighter arrow is often why some hunters don’t want a “higher FOC” arrow (since adding more weight to the front of the same arrow, with inserts or heavier broadheads would increase FOC, but also slow the arrow down.)

tuffhead broadheads

Consider heavier broadheads and/or inserts when seeking a higher FOC. An arrow with an FOC of 8-12% FOC could be considered “normal,” while a “high FOC” arrow would start around 15% and can go up to even 30%.

Others want an arrow that has a higher FOC %, (you may have seen The Ranch Fairy discuss this) so that the arrow hits the animal with a heavier impact. This can increase the odds of a “pass-through” shot. It can also help increase the chances of a mortal wound in the event you encounter bone or other stiff tissue that might impede the arrow’s progress.

Hopefully you find our FOC calculator helpful and we hope you have an arrow that’s Just Pass’N Through!

Final Thoughts on the Coleman Sun Dome 4p Tent with Darkroom Technology

We picked an extremely hot and sunny day to set up the Coleman Sun Dome 4p tent. However, that turned out to be perfect, because we were able to get a good feel for how much light and heat the Darkroom Technology blocks.

Well, it was still really hot inside the tent. And, while we didn’t have any kind of light meter to test the light level, it was in fact significantly darker inside the tent.

The Sun Dome 4p tent folded up nice and neat and went right back into the small carrying bag fairly easily!

All in all, the Sun Dome 4p tent seems like a great tent for the money!

Urban Deer Hunting… The Entertaining, Challenging, and Useful Suburban Whitetail

-By Jerald Kopp

The abrupt honk startled me.

Unbeknownst to me, I had slowed the truck to a crawl as I surveyed the thick urban wood lot. Suffice to say, the car behind me didn’t appreciate it.

The greenbelt sat behind a gas station and next to a small pocket neighborhood. I had caught a glimpse of a familiar resident… It was “Shaggy,” a disheveled old buck that still donned his velvet on the early December day.

shaggy the suburban buck

“Shaggy” is just one of a growing population of whitetails in suburban areas around the country.

But it wasn’t his set of antlers that justified his nickname, rather his mangy and matted coat. Shaggy always had a bad hair day – at least for the last couple of years. He wasn’t seen often, but this section was his core bedding area and the number of fender benders I almost caused here were too many to count.

Urban and Suburban Deer: A growing segment of the whitetail population

Urban and Suburban deer have been multiplying around the country for years. Even though hunting them is illegal in my hometown of Austin, Texas, deer nerds like me are always on the lookout for them. In fact, during the pre-rut and rut, I see an amazing number of shooter bucks within a four-block radius of my house alone. The untouchables I call them.

I’ve learned every wooded and semi-wooded area in my part of town and survey them regularly. I’ve also discovered various bedding areas, funnels, and trails in this mostly concrete jungle.

I’m told I need to get a life, but I’m okay with that.

I have a friend (who will remain nameless) that has long since been known for his bow hunting escapades in suburban Austin. A commercial real estate professional, he’s never had a shortage of unoccupied greenbelt sections to visit with his bow in hand. He was once known for his common strategy of putting on camo over his dress clothes for impromptu bow sits.

I’m not a proponent of law-breaking but have to admit that I loved his stories. Plus, much of Austin is mired in a massive overpopulation of whitetails. Some areas are so crowded with deer that many live an unhealthy existence.

For me, this softened my friend’s violation. Conservation and herd management indeed.

Urban Deer Hunting | It’s Tougher Than You Think

Suburban deer hunting presents unique challenges. I get a kick out of the common misconception that these deer are tame and, hence are easy to hunt. Consequently, the idea has been cultivated that all deer are easy to hunt and it’s not hunting at all. This mindset largely comes from some of the city dwellers that encounter them (many of them of course, anti-hunters).

When it comes to bucks (especially mature ones), this couldn’t be further from the truth.

Just because you might see them in the “wide open,” doesn’t mean suburban deer are easy to hunt.

How do they hide in plain sight?

I’m still astounded by the random sightings of huge bucks in my neighborhood; often seemingly new ones. On many occasions, I’ve sat in my truck dumbfounded asking myself, where has this buck been all this time?

Sure, there are the deer groups often seen on manicured lawns. However, it’s not always the case, especially with mature bucks.

Despite living amid constant human activity, urban deer no doubt have people patterned. It has much to do with familiarity and hunting them is another matter altogether.

Just like in rural settings, changes in human activity promptly throws a wrench in whitetail tendencies.



“It will truly give you a new appreciation for what a deer will tolerate in its daily life. And, how quickly when one small thing steps out of that “normal” routine, a deer will take notice and alter its behavior in order to figure out what’s going on,” says Taylor Chamberlin of the Urban Deer Complex 2.0.

Tyler and his outfit tenaciously study and pursue the urban whitetail in the Washington, D.C. area – another region that houses an exorbitant number of deer.

Currently, there are many successful urban and suburban deer hunters around the country in areas where it’s legal to bow hunt them. In fact, suburban bow hunting now represents a popular niche in the outdoor industry, social media, and outdoor culture, and it should come as no surprise.

The ability to live in a setting full of consistent human activity adds more proof to the resiliency of the whitetail deer.

It’s astonishing the number of trophy class bucks that are taken a stone’s throw from playscapes, soccer practices, and strip centers. If you pay attention to hunting-related social media and other channels, you will no doubt hear stories about huge bucks taken within, if not near city limits.



There is no better example of such success than Lee Ellis and Drew Carroll of Seek One Productions who has had incredible deer hunting success right in the suburbs of Atlanta. In fact, they’ve taken bucks of massive proportions – bona fide trophy class whitetails.  

“Our goal is to show people that adventure is not constrained to wild remote places and that hunting is not defined by big woods and rural parts of the country,” said Ellis. He continued, “If you look hard enough, adventure can be found in the most unexpected places and can become part of your everyday life like it has for us”.



Suburban Hunting Tips

Deer hunting within and near cities and towns isn’t easy and takes work.

First, it’s difficult to get hunting permission and requires persistence. Be prepared to ask and ask again. Your odds are greatly increased if you can procure permissions on contiguous sections.

When hunting and scouting, it’s important to locate the areas with the best cover and better yet, their associated pinch-points. Think low impact. Drive the roadways and be willing to glass from both roadsides and parking lots before you ever attempt to set up a blind or deer stand. Deer are much more used to vehicles in these settings.

Even if hunting with a bow and arrow is allowed in your suburban area, be sure to still obtain the proper permissions before hunting whitetail.

If they exist in or within the city limits, examine fields from a distance (especially agriculture). Finally, keep your ears open.

Much like in the country, the rumor mill is powerful. This is a good way to get info on good area bucks.




Leveraging Suburban Deer Intel for Rural Hunting Success

Finally, use suburban deer behavior (and hunting) to your advantage. It can be beneficial to your more remote hunting pursuits.

Urban and suburban deer hunting provides an opportunity to study deer behavior without heading to the ranch, lease or public hunting area. I’ve often said that my neighborhood is my classroom with lessons and experiences at the ready. As a whitetail hunter and enthusiast, it’s a gift. Simply observe and you’ll become a more proficient and educated hunter.

While there are differences in hunting near the city limits vs. more remote grounds, there are similarities as well. I’ve found that monitoring deer behavior in mine and other Austin neighborhoods has helped my rural hunting immensely.



On numerous occasions, I’ve seen first-hand the beginning of the rut in my ‘hood – heck sometimes even in my cul-de-sac.

The year 2018 was no different. It had an earlier rut period than in previous years. I woke one early November day to find that the switch had indeed been flipped. Many amorous, persistent and committed bucks were on their feet. This deer hunting geek was stoked.

It didn’t take me long to pack the truck and drive the two hours to our family farm to take advantage of the opportunity. And it paid off. Yes, all those reports predicting an early rut were true and I had first-hand proof – and time to strike. Game on.

Hunting in urban settings also presents an opportunity to practice analyzing deer sign, trails, and calling skills – and become a better hunter.

Finally, there are other benefits of hunting in urban areas, including herd management, recreation, and positive economic impact on local communities. From an outdoor tradition, legacy, and conservation standpoint it also widens hunting’s (particularly bow hunting’s) reach and footprint.

Though I won’t hold my breath, I hope to be able to bow hunt whitetails in the greater Austin area someday. In the meantime, I’ll continue to be entertained and educated by them.

On the other hand, if you live in an urban or suburban area where it’s legal, do your research and get after it. You may be surprised by what you find.
