Simple, quick, bowrangefinder idea

Dr_Hunter · Apr 22, 2018

LAST EDITED ON Apr-22-18 AT 10:44AM (MST)[p]Hey guys,
Check this out. I'm helping a friend with an idea that he's come up with and created. It is a simple rangefinder that attaches to your bow and tells you the distance of the animal based on it's width measurement (shoulder to rump) and frontal width. It straps to your bow and at full draw you can determine the distance of the animal in pursuit. What I love is that it eliminates the need to range and/or re-range the animal but stay at full draw and be more lethal... and it works!! See the pics below and tell me what you think. I'd appreciate your feedback on the idea.

Rangeviewer on the bow

Actually looks like a great idea that would be legal in all states. The only question I would have is would different draw lengths effect accuracy? There could be a 6? difference from one mans eye to the next.

Seems like a good idea I will have to try it out and see how accurate it is for me specifically. That would be awesome if it was super accurate, just a couple yards off could be a huge deal.

Each device (Rangeviewer) is draw specific. They're pretty accurate. The human eye is amazing. What I am noticing is that I am becoming better at judging distance by looking at the animal size rather than being completely dependent to my rangefinder. I am excited to use it this hunting season.

But how do you range those 100 yard shots ? ;-) Do you have to change the unit out for mule deer?

Similar concept, people seem to like it...

100 yd shots John! This goes on your bow not your rifle

The unit will range out to 70yds, so it will keep things somewhat challenging for you

Yes, you would have to change the unit out from deer to elk. So far we have them designed for mule deer, elk and whitetail. We're looking into possibly making a deer/elk combo... maybe.

Dr_Hunter · Apr 24, 2018

Similar concept to the EZVsight; however, we believe our device will be more accurate because we are measuring a larger part of the animals body. In addition, what I like more about ours is that it will still allow you to use your own sight rather than relying on the combo.

But where are that batteries???
Every new piece of hunting technology needs batteries!!!

Nice work!

Seems all good except when in the field your animal usually is at incline or decline angles. Then what? How does it compensate for angled shots.

MT_55 · Apr 25, 2018

Darn Cool idea!!! One of those where I wish I woulda thought of it. Good luck guys and keep pushing.. Plenty of people will question and say it's no good but if you believe in your product and it works,, it will work!

Also it looks like this is accounting for a broadside shot only, what about quartering away at hard angles?

Dr_Hunter · Apr 25, 2018

Batteries not included Littlebighorn, nor are they needed! Ha ha!

As for the angle compensation we have been doing a lot of testing from tree stands and the roofs of our homes and have found it to be accurate; however, it does not do angle compensation like today's rangefinders. Of course, that part you will need to do in your head.

If you recall back in the day when rangefinders came out, they were constantly preaching that if you hunt from a 15'-20' tree stand your angle compensation was minute or just a few yards. A lot of whitetail hunters will tell you the same up to 40yds. The problem with up and down shooting is the form errors/differences between shooters. There are a lot of variables and not everybody shoots the same, [maintaining perfect flat ground geometry on the shot] thus the reason for practicing to see what works for you. For example, some people tend to heel their bow on an uphill shot, but not on a downhill. We recommend becoming very familiar with your bow and your set-up. The more you learn, the more lethal you will be in the field.

Here is a good website that discusses and further explains angle compensation.

I included a chart that shows the differences.

Dr_Hunter · Apr 27, 2018

Quartering or hard angle shots will still be accurate up to 22.5 degrees. When a deer turns it's hind end or front shoulder extends, it will add to the 2D length of what our eye sees when the other eye is closed. Again, you will have to use your best judgment, a randgefinder or just not shoot if it is questionable and wait for a better opportunity.

The marks on the bottom of the Rangeviewer will range frontal views of the animal, measuring the frontal/anterior width of the animal.

There is no perfect tool out there they all have draw backs this one included but i do think this could be handy and in the right situation it could be a difference maker. How does someone get there hands on one or when is the estimated time it might be out on the market.

LAST EDITED ON Apr-30-18 AT 03:57PM (MST)[p]Well put notdonhunting. We are planning on the Rangeviewer being available to purchase over the summer. Hopefully, the beginning of June. We will let you know. There is more info on Instagram @ Rangeviewer.
We have over a dozen prototypes being tested right now. I should mention that we have researched the size of deer, elk and whitetail so that a person can use the Rangeviwer with confidence and have all the information they need. The previous pics were of a left handed model. This is the pic of a R handed model.
