Descripción del producto
Función de medición por tres puntos: la altura de un árbol se calcula usando la distancia horizontal y los ángulos de la copa y de la base del árbol. Su fácil manejo permite medir la distancia real, la distancia horizontal y la altura. El sistema de conmutación de prioridad al objetivo ofrece dos modos de medición: El modo de prioridad al objetivo más distante muestra la distancia al objetivo más lejano entre varios resultados obtenidos con una única medición. El modo de prioridad al primer objetivo muestra la distancia al objetivo más cercano entre varios resultados obtenidos con una única medición. Los resultados de las mediciones se muestran tanto en la pantalla LCD interna como en la externa. La pantalla externa muestra todas las medidas simultáneamente. Monocular de 6 aumentos de gran calidad con recubrimiento multicapa para imágenes luminosas. Su diseño de punto de mira alto aumenta la claridad del campo de visión, incluso para los que llevan gafas de protección. Capaz de medir la distancia de diferentes objetivos sucesivos manteniendo el botón pulsado hasta 20 segundos. Resistente al agua (hasta 1 metro durante 10 minutos), pero no diseñado para usarse bajo el agua; el compartimento de la batería es resistente al agua. Rango de medición: de 10 a 500 m.

The great thing is that you can look through the eyepiece, aim at a target, press and release the button, then look at the LCD on the side: It will tell you how far above or below your eye the target is, the horizontal distance to where a plumb bob dropped from the target would be, and the straight line (diagonal) distance from your eyepoint to the target.
There's also a reasonably straightforward way to put it in a mode where you can aim at the top (or bottom) of something (a tree, a building, etc.) and click the button, then at the bottom (or top) of it, and the LCD will tell you how tall the thing (tree, building, etc.) is.
There are other modes, but trying to navigate through them with just the two buttons is something you'll never remember, so carry the manual with you (or a cheat sheet) if you regularly need to switch between them.
My gravel driveway is about 950 feet long, and has a concrete block wall at then end away from the street. I took great care in embedding into the driveway markers every 100 feet from the concrete wall out to 900 feet. The 900 foot marker is within 3 inches of the correct distance. I put the rangefinder in the mode to measure in feet. On many different occasions over the past six months, in the cold of night and in the blazing desert sun, I measured the distance from the concrete wall to each marker. In general I got similar results under all conditions, which were most often:
100 foot marker measured 99 feet.
200 foot marker measured 200 feet.
300 foot marker measured 301 feet.
400 foot marker measured 401 feet.
500 foot marker measured 504 feet.
600 foot marker measured 604 feet.
700 foot marker measured 704 feet.
800 foot marker measured 804 feet.
900 foot marker measured 906 feet.
When the weather was cool (say 40 to 60 degrees F) the 900 foot marker would often read 902 feet, but in bright sun, and at 70-95 degrees F, it most often read 906 feet.
As with any laser-based distance meter the further you are from the target the harder it is to hold still enough to keep the aimpoint on target, and the more it's recommended to take several measurements and see which number comes up the most often.
It won't measure distances below 33 feet, which I have found sometimes frustrating.
There's not quite enough eye relief: with glasses, and even with the rubber shield folded down, the edges of the visual field tend to go fuzzy white. How bad this is depends upon how much the sun is shining into the objective lens. If I take my glasses off, adjust the focus, and put my eye closer than my glasses allow then I can see the whole visual field clearly.
There is no illumination, either in the eyepiece or in the LCD screen. You can usually see both clearly enough down to relatively dim twilight, but not when it gets darker than that.
It's got a CR2-sized battery. This is a standard but relatively rare size, so I'll have to order spares and replacements, rather than dropping by the local store. I really wish they had used the larger CR123 battery, which is far more common.
It's cool to be able to measure the distance and height of far off trees, telephone poles, buildings, etc.
It's named a "Forestry" product. I would think that it would be awesomely useful for field measurements of trees, etc.
But for my use, I need it more for measuring distances for landscaping and parking lots, and inside buildings, etc. I guess it's accurate enough, and being able to work in bright sun is great, but sometimes I find the inability to measure distances shorter than 33 feet to be frustrating.
Unless you need the features a surveyor might, the product is more than adequate, and superior to the typical sporting type rangefinders on the market. The Forestry Pro's LED screen on the side is very useful, and the clean crisp viewfinder display is right on target. I like the yellow color because if you set it down you can find it more easily.
I did have some trouble getting this product due to the high demand. The second order from Suppliers got me prompt and efficient delivery when the recommended supplier could not produce.
I think that this is a very useful product, but it could be much more useful. It definitely saves a lot of steps from plot center: if a tree is at 35' it's in, if it is at 38' it's out. But for, say, a 20" dbh tree at 36', you have to use a tape because it is only accurate to 1', so the tree would be on the plot at 36.2' to the front of the tree and off the plot at 36.5'. And good luck figuring out if it rounds up or down.
So accuracy to 0.1 feet would be extremely helpful.. Granted there are way more expensive rangefinders for sale which don't do any better. But if Nikon is serious about forestry they should address this. I know they could do it because every carpenter's laser out there can do it. Also it fails to read out at less than 33', so you can't tell if the vegetation is too thick to get a reading or if the tree is too close. This isn't very helpful.
I like the scope - it makes it easy to find a bare patch on the stem to shoot at instead of trying to hold a laser dot steady. And I Iike no laser dot to get in anyone's eyes. I have had mine for 6 months and have had no problems with it so far. I have used it in rain, heat, snow, high humidity, dark conditions, bright conditions, etc.
I would buy another one if something happened to this one and nothing that addressed my particular concerns was available.
