Get em' in to 10-15 yards and don't worry about it.

Thats actually really great advice. I know its not what you want to hear but that alone will help you alot more than string, tape, and proximity sensors.

My motto with a bow is this: If it looks like it might be too far, then its TOO FAR!

I have thought aout making my own a few times. It is a very simple circuit, the problem I have is getting a case to put it in.

You just need a proximity sensor and a microcontroller. Press the button it sends the signal and starts an internal clock. Once the return signal is received it stops the clock. And you can now turn time into distance because you know the wavelength of the signal.

I am going to make one and I will let you know how it turns out.

Hey Wheatly, I mean Macgyver,

When you get that puppy going I sure would like to see it. I'd like to know how accurate it is too. Very interesting.

RE: homemade range finder

I found another problem in finding a sensor that will meet the range I need. I will keep looking and hopefully come up with something. I thought I seen one that would go to 60m but now I can not find it.

A 250 fps or faster bow and a good pendulum sight, you are good to 35 yds with a single pin. It is as easy as that.

With 280-290 fps depending on which bow I shoot, it is pretty easy. No clear shots past 20-25 yds in the woods anyway. No need for a pendulum here. My 10 and 20 yd pin is the same, and my 30 is stacked right below it. I couldn't figure out why your bow was so slow TeeJay, then I remembered you shot a mathews. Better stick with the pendulum;)

Get a $9 binocular from walmart. Stand 15 yards from a crisp target and focus it in with the binocular. Make a mark on the bino focus - this is your 15 yard mark.

Do the same for other distances.

I saw somewhere that some one went 20, 30, and 40 yards away from a 3D target and used a paint marker on the outer edge of their sight and marked a spot where the back of the deer is then 3 other marks where the gut of the deer was. Im not sure if it works well but its free so its worth trying. I'll see if I can find where I saw this.

RE: homemade range finder

buy some judo points, and walk around shooting at grasses, flowers, stumps, etc. after every shot count the yards to whatever you were shooting at. after a while, you'll get pretty good at it!

RE: homemade range finder

Hey, when you are shotting long distance w/ a rifle llike out to a couple hundred plus yards you use yardage markers in the form of a stake and some clothe llike material to blow inthewind. Why don't you set this up at your stand site? I would (if i was as concerned as you are) start at 20yds then 30yds then 35,40...prob.would not go much further than that..good luck.
