PLRF 10 C some pictures

[one shot ST]

Pictures taken from my suites in Mauritius Islands... some considerations, in Italy now is difficult to range more then 2300 meters, Vectronix says that detection capability with an ALBEDO of 0.4 ( 40% ) is about 90%....

AlBEDO from wikipedia....

Albedo (English pronunciation: /ælˈbiːdoʊ/), or reflection coefficient, is the diffuse reflectivity or reflecting power of a surface. It is defined as the ratio of reflected radiation from the surface to incident radiation upon it. Being a dimensionless fraction, it may also be expressed as a percentage, and is measured on a scale from zero for no reflecting power of a perfectly black surface, to 1 for perfect reflection of a white surface.

The tropics Although the albedo-temperature effect is best known in colder regions on Earth, because more snow falls there, it is actually much stronger in tropical regions which receive consistently more sunlight

So a friend of mine with a PLRF 15 C in Kosovo was not able to range more then 1000 m....on the snow

Vectronix say that this happended due a different frequency laser frequency between PLRF 10 and 15.....

My report is at my latitude in Italy at present time I can range maximum 2300 meters....

today in Mauritius I laser more time over 2600 meters..and sometimes I've seen 2705 meters.

temperature 28 celsius, 80% relative umdity, scattered clouds...

somebody has more info about laser range finder and albedo ?

Very cool thanks for sharing!

Re: PLRF 10 C some pictures

Much will depend on the laser wavelenght, backscatter from particulate in the air and the reflectivity of the target IN THE LASER WAVELENGTH.

Between the 10 and 15, you have two key differances. The 10 is a 905nm and the 15 is a 1550nm laser. The 15 is not visible to image intensifiers, the 10 is. 905 offers better reflectivity on most surfaces. The beam size is also different, the 10 is only .3 x 1.3 mil, where the 15 is .5 x 2 mil. This simply puts less beam on a small taget, making the detector work harder to register a valid range.

With a highly reflective surface like snow or water, the detector must be able to separate the natural light reflections from the units laser. If the target is less reflective of that wavelength than the background, readings may become impossible. This sounds like the problem in Kosovo. The day was likely bright and sunny, or snow was falling and scattering the beam. Had it been overcast but clear visability, it would change the results.

Thanks Cory.....

Re: PLRF 10 C some pictures

i was under the immpression that the smaller beam of the 10c was more accurate on small targets, is that incorrect?

Re: PLRF 10 C some pictures

The smaller beam is better in that you get more of the beam on the target, therefore more reflection of that beam. That may get you a range, it may not. It still depends on the ability of the receiver to pickup that reflected energy and discrminate it from the background. It's possible that a target is minimally reflective to the 905nm wavelength, and even though it is the exact size of the beam, you don't get a range due to the target absorbing the energy. Use the larger beam, but at a different wavelength, which is better reflected and you get a range, even though the beam is not totally on or reflected by the target.

It's a lot more complex in the engineering than most users realize. We can only speak in generalities. This is why some will try to compare a Newcon unit to a Vectronix unit based on the mfg spec sheet. There is actually no comparison to be made, since neither spec sheet is definitive enough to be able to march specs. In actual use, the Vectronix units completly crush the Newcons in capability and ease of use, but unless you can do a side by side comparison it's pretty had to tell that from the spec sheets.

The 10 is more than adequate for any anti-personel sniper system available. If you are talking anti-material, where the targets are larger and beyond 2500 yards, step up to the Vector IV or even the 21 if you feel the need for overkill. I can range a small tree, house, or rockpile at 4K with IV's. 21's will get 10K on the same target. 10's are comfortable out to 2K+ under most shootable conditions, sometimes 2500+.

The keys are how big/reflective is the required target, what are the worst conditions required for operation, what is the max range needed for that situation? Select the unit which will do that at half to 1/3 over your max range and you should be good better than 99% of the time.

Re: PLRF 10 C some pictures

I wish I had read this before I purchased my Newcon. From the specs I couldnt really tell the difference between the two. When I started using it the programming wasnt as simple as it should be. When I used it with my Nomad and FFS the profiles kept changing every once in awhile. I used one of my friends, PLRF10C, its super easy to use, instantly compatible with my Nomad and FFS and the size of the unit makes it much easier to take in the field. I sold my Newcon which is a good laser and bought a Vectronix which so far has done everything I need it to do. Thanks for the info, always informative.

Re: PLRF 10 C some pictures

Fellas,

Can any of you school me, on getting my Recon to recognize my PLRF-10.

I just picked up the data cable, and have no idea how to get the devices to communicate.

I am running FFS Delta III on Windows Mobile 5.1.195.

Any help would be greatly appreciated.

Re: PLRF 10 C some pictures

Plug the data cable in at each end. Got to Ranging, Rangefinders and select PLRF. The default port is Com1 and the default baud rate should be 9600. Select Start. Now when you trigger the PLRF from the trigger switch, the range, angle and bearing will be fed to the system and the solution calculated.

Re: PLRF 10 C some pictures

I don't have a "Rangefinders" option showing up under my ranging tab... do I have the proper components to run this?

PLRF-10 (not 10C)
Recon Mobile 5
FFS Delta III

Re: PLRF 10 C some pictures

You cant run a range finder with the delta 3 software. you will have to upgrade to delta IV.

Re: PLRF 10 C some pictures

Ugh.... I was afraid of that.

Thanks.

davide... sorry for the thread hijack...

Re: PLRF 10 C some pictures

Tribe ,
u need the PLRF10"C" version ,
PP out

Re: PLRF 10 C some pictures

I don't think the recon will run delta IV

Re: PLRF 10 C some pictures

Just some more pics PLRF10. They really are in a league of their own. I don't feel that 6x power hinders at all for anything practical. Keep in mind these pics are with my phone.

Wow.... now that is some clear ranging!

Any chance you'd be willing to post some shots of ranging something like the size of a deer or dog (coyote) at 200-600 yards?

By the way, thanks for posting these pics, I've been thinking about saving up for a high grade LRF.

Holy cow... just googled them off to the side... it will probably be a little while before I drop 3k+ for a LRF....

Re: PLRF 10 C some pictures

He is at 300 yards. You loose some perspective with a camera phone. It is a bit deceiving, as a dog at 400 yds is pretty easy to hit standing freehand.
