HCO Rangefinder Model Okoo RF-1000S

The good people at HCO took time off from their camera business to screen the market for another associated item that they could add to their inventory of products. This new product is the Okoo RF-1 rangefinder. This is a small 4 ½ X 3 ¼ inch handful comes in a soft flat black color. It is about the ultimate in being non reflective other than the two main lenses. The optics are fully coated and are fixed at 7 power. The objective lens is 25 mm and tucked back under a protective rubber lip. How does a camera review outfit take on a range finder for the purpose of a review? Well it started like this, imagine you have a main road through your property and you want to space several cameras along this road at a given distance during that time of year you are doing your game census. The interval is 40 yards and the road is about a mile long. The old tape measure or the “stepping it off” thing will work but involves a lot of work. With the range finder it is just a push of a button to view the exact tree that is at that distance. In the case where trees are few and far between and all you have is brush (Texas) then you need a second person to move down the road and you can shoot of him to get the distance. After the cameras are set up, you can use it for setting up your stands and measuring off to certain shooting spots. Once you get use to having one then when it is not there you will miss it. The closest distance that the Okoo will measure is 12 yards and the max distance is 990 yards. This does not mean that you can measure the distance to a deer at that distance. What it means is something that is large and reflective like a building can be measured. Small animals like deer can be picked out to about 300+yards and trees can be measured to around 500 yards. I have been giving all the measurements in yards but this rangefinder will also switch to meters for those that prefer that method. This range finder has an accuracy of plus or minus one yard, which is pretty close for people who need the shooting distance to allow for bullet drop. This is even more critical for those archery users who practice at given yards and have their pins set to those distances. Once in the stand it is easy to shoot a bush or tree with the range finder to pick out distances around the stand for that time when old big moves into the area. The use of a range finder during early morning hours when the light is weak is very good. The coated optics help to pull in the light and when I did this I was able to pick out detail that I definitely could not see with my naked eye. At 7 power it can also take the place of binoculars when what you carry to the field must fit in a certain space and limited. A couple of standard AAA batteries are all it takes to get this thing on the road and there is no learning curve. I ran through a bunch of my catalogs and this little devil is a lot cheaper than what is in the catalogs and it has like features. I bought several over the years and when Anthony decided to become William Tell and took up archery I bought one for him to use. His method is to stick some small ground markers at different distances around his stand. I can see no difference in the measuring ability of any one of these brand names. This is a rugged functional tool which most anyone would be proud to take to the field and use. Being it is a field item it has to be weather resistant. This does not mean you can jump in the lake with it in your pack while dodging a bear and expect it to not get wet. But it can be used in the rain to do a measurement without fear of problems. The nice small size will allow it to fit in a jacket pocket which my high dollar finder will not come close. I have to keep it around my neck or in the pouch on my ATV. The price is less than $200 and is available at most HCO dealers. I spent the afternoon zapping distant trees with my high dollar $499 and this HCO range finder. Mine has some bells and whistles that I never use but did have one feature that would allow it to be used in the rain. These devices shoot out a laser bean and then it will wait for it to be reflected back and this stops the timer. The amount of time is converted to distance like radar does when it is looking into the sky at a distant plane. When it is raining the beam would bounce off the rain and come back to soon and give you a false reading. For the extra three hundred dollars I guess I could wait for the rain to stop to take the measurement. Even though this tool does not have the rain feature it did turn in identical measurements as the other rangefinder it was up against. Both measured by tape and by range finders showed this range finder is accurate and dependable. A very good buy for the price.
