This was the second rangefinder that I've tried. This one is a keeper; ranges quickly, accurately, doesn't vary when held on an object. Mounted to tripod to ensure no motion from me, as before. Ranged to a building, some vehicles and an RV and distances were accurate and didn't vary.

I have wanted to get into long range shooting and needed a range finder to determine exact distance. This range finder is spot on in comparison to several other manufacturers. For the price this range finder just can't be beat.

Nice quality product so far. Several options available in settings. Instruction manual available online only. Easy setup. Only had a few months but so far so good. Don’t have any regrets. Second bushnell rangefinder I’ve purchased. Purchased this for rifle hunting as my other one only goes to max of 400 yards. Display automatically changes colors for low light conditions for clear contrast. I like the larger objective lens and 6 power magnification.

I had a bushnell 1000 arc and decided to upgrade. Very clear glass and much faster report than the 1000arc. The Prime 1800 gives bullet drop in Mils or Moa which work great. It also gives drops in Inches and Centimeters which does not. I tried contacting Bushnell to explain but not sure the understood. The 1000arc gave only inches and it worked. Example for a 308 with 100yd 0 it drops approximately 15in at 300yds which is what the 1000arc would tell me but on the 1800 prime it tells me 1.4 Mils which is correct, 5 MOA which is correct but only 5.2 inches or 13.2 cm which is incorrect should be 15 in or 38cm at 300yds. Its giving a difference of moa and inches which is 1.047 not actual drop at the given distance the only way it would work is if you had an inch or cm reticle to use instead of moa or mil. As far as i know they dont make inch or cm reticle. Other than that works great just stick with moa or mil and you'll be ok

UPDATE: October 22, 2023. It's been about a year and a half since I purchased my Bushnell Prime 1800 rangefinder. This is still a 5-star unit. I don't make money promoting stuff on the internet. I'm just a guy who likes to shoot guns and I feel bad for other shooters that are looking for a rangefinder and are overlooking this hidden gem. Bushnell kind of screwed up the marketing of this rangefinder. Actually, they are still screwing it up a bit. Maybe that's the reason that the price has dropped to currently $199 USD (this is good news for buyers). Bushnell gave this unit a name that is easily confused with their Nitro 1800, which has bluetooth stuff (the Prime 1800 has no bluetooth stuff). Even resellers sometimes put in their specs of the Prime 1800 that it is bluetooth compatible because they confused it with the Nitro 1800 specs. People who wanted the bluetooth stuff that the Nitro 1800 has have accidentally purchased this Prime 1800 unit and then badmouthed the Prime 1800 because "the bluetooth doesn't work". Another thing I see that Bushnell marketing is doing wrong is showing a little video clip of the display where the right side of the display has a line going up around the right side that looks like the volume indicator on an audio amplifier. Thank goodness the Prime 1800 does NOT have that irritating thing -- nobody wants or needs that and it probably has scared off a lot of people from even considering buying the Prime 1800. Another thing that probably keeps people from considering buying this Prime 1800 rangefinder is that Bushnell markets another rangefinder as a "bow hunter's" rangefinder, which implies that the Prime 1800 is not for bow hunting. The Prime 1800 can measure in feet out to bow hunting ranges just like the bow hunting unit can. The Prime 1800 user's manual and specs on Bushnell's web site only mention yards and meters and accuracy to +/- 1 yard, but they are only talking about accuracy out to a mile. If you set the unit of measure on the Prime 1800 to be not yards and not meters, then the measurement is in feet. The feet measurement is not just yards multiplied by 3 -- it is actually accurate to 0.3 yards just like the bow hunter's rangefinder out to a distance of (I'm guessing) 150 yards -- same as the bow hunter's rangefinder. And currently the Prime 1800 is $199 and the bow hunter's rangefinder is $299. The Prime 1800 also shows line-of-sight distance, angle (elevation) to target, and horizontal distance just like the bow hunting rangefinder. It doesn't matter if you are shooting with a bow, a bb gun, or a high-powered rifle -- the only three pieces of information you need from your range finder are what the Prime 1800 gives you. One "feature" of the Prime 1800 that I don't think many people will use is "rifle mode". It's OK that it is there, but most shooters will just plug the range and elevation into their choice of ballistics programs (apps). Some people's reviews of the Prime 1800 complain that the batteries don't last long. Just buy the best batteries you can find and throw out the ones that come with the range finder. This unit is a low-watt unit and good batteries will last a very long time -- I ranged over a thousand targets in a week and the batteries still were not dead. I could write a book about how awesome the active-sync display is, but I'll keep it short. If you shoot at dusk or dawn or in bright conditions where contrast is unbearable (like a snow-covered mountain side that also has rock ledges and caves and deep brush that look black compared to the snow), then you will love the active-sync display. Other range finders have illuminated displays, and I've seen 'em, but they just don't compare to the active-sync display of this Prime 1800 range finder in my opinion. So the bottom line is that this range finder is a hidden gem in my opinion. The stuff below is my original un-edited review from when I bought my Prime 1800. And just to be clear, the model number of my Prime 1800 rangefinder is LP1800AD. It is stamped (imprinted) on the case -- not just a sticker.This review is probably going to be long-winded and jump around from topic to topic in no particular order. That's just the way I am. So far I really like this rangefinder. I say "so far" because I have not yet used it in the desert in the heat of summer. I have not yet used it in the mountains at near zero degrees fahrenheit. I haven't used it in the rain or snow or fog or high winds that kick a lot of dust into the air. So far it's been about 60 degrees F sunny to completely overcast. Pretty much I've just been ranging trees that are in my neighborhood. I know everyone wants to know how far I was able to range "stuff" to see if Bushnell's claims of 1800 yards on reflective objects, 1000 yards on trees, and 700 yards on deer are exaggerated. I'll get to that in a second, but again keep in mind that really cold mountain temps and hot flat deserts are always a challenge for any rangefinder and I can't do that right now -- it's nice late April weather. As with any rangefinder, you should only EXPECT to get half of the claimed range and be pleased when you get more than that. So my best range on a tree was over 1300 yards. I could only get that far once on trees, but within 800 yards trees were easily rangeable. Over 900 yards was common and nearly expected. So with that I say Bushnell's specs for optimal ranging ability on trees is not exaggerated. Since I live about a mile from the end of an airport runway and I didn't feel like driving out to the desert to try for farther targets, I started ranging planes that were taking off and climbing at steep angles. Aircraft are really difficult targets because they are shaped like curved mirrors and just reflect the laser light off at a glancing angle. When the specs say 1800 yards on reflective surfaces, a lot of folks might think an actual mirror would be perfect, but it's not. A reflective surface that is NOT smooth is what actually makes a good target for a rangefinder. So without any expectations of being able to range aircraft, I gave it a go. I tried lots of planes with no luck, but I did manage to range some Boeing 737s at ranges from over 1200 yards to over 1600 yards. I ranged a Lear Jet at over 1400 yards. I ranged some twin prop commercial planes as well and one at over 1700 yards. That pretty much gave me the answer as to whether or not this rangefinder could reach out to 1800 yards on optimal reflective surfaces (since planes are far from optimal). As for ranging deer -- couldn't find any here in the city. My next subject has to do with the ability to tell the rangefinder to show me the nearest distance, farthest distance, and the "just tell me what distance you currently have regardless of whether it's closer or farther than the previous distance" mode, otherwise known as scan mode even though all three modes are actually scanning multiple times per second. These modes are very important and extremely useful to me. I have lots of situations where I need to switch between them as quickly as possible. The Prime 1800 makes this as quick and easy as it gets. Just click the MODE button to switch from one of the three possible modes to the next one. That's it. Regardless of which hand you are holding the rangefinder in, your middle finger is always right on the MODE button and your index finger is always right on the FIRE button. Many other rangefinders, for some silly reason, have the MODE button on the side of the rangefinder rather than on the top of it next to the FIRE button. I hold my rangefinder with my left hand just as much as I do with my right hand. If the mode button was on the side, then half the time I would not be able to hit it at all. Even if I had it in the "correct" hand, I don't see how pressing the MODE button with my thumb on the side could possibly be easier than hitting it with my middle finger on top. So, for me, the Prime 1800 is right on with both buttons being on the top. I also want to point out that the buttons are very stiff and tactile, which means you won't be accidentally pressing them. You get a good solid click when you push these buttons and I like that. Another thing that might seem trivial, but worth mentioning, is that the shape of this rangefinder is a bit like the grip on my .45 automatic colt pistol where the web between my thumb and index finger just naturally locks around the skinny part right behind the trigger. So even if I grab this rangefinder with a muddy or snow-covered hand or glove, it is going to naturally slide right into the perfect position and there's no way it would slip out of my hand unless I intentionally let go. So now about the information shown in the view. I really like that this rangefinder shows ALL of the information I want after getting a range on something and have 8 seconds to look at the line-of-sight distance and the horizontal distance, and the incline/decline angle. Having all three of these values is important to me. Some reviewers of this rangefinder say that it is too busy for their personal taste, but I prefer getting all the info and I don't find any of it being "in the way" of me getting a good hit on a target. The pointing reticle is perfect to me with the dot inside a larger circle. Switching it to a center dot or just the larger circle takes me less than 7 seconds, but I'll probably never change it. It's the best for me in all conditions. As for the red/black activsync display -- it is awesome as other reviewers here on Amazon have already mentioned. The activesync display is hands-down the best I have personally seen in a range finder. The 6X view brings in a lot of light -- more than I expected and that is a GOOD thing. So far everything I've said about the Prime 1800 is all good. Oh, I almost forgot to mention how much I appreciate Bushnell making this rangefinder directly attachable to any camera tripod with standard 1/4-20 threads. Some other rangefinders require that you spend more than $100 to buy a clunky adapter just to put your rangefinder on a tripod. I just now remembered something else that folks might want to know. When you see pictures of this rangefinder's screw-on battery cover/cap, you probably wonder how likely the hinged flip-out part is to break (I wondered that and was a little nervous about it). Well, I still don't know if it is plastic or metal -- I think it is plastic, BUT the actual hinge pin is steel and runs across the entire diameter of the cap. I don't think it's likely to break unless someone gorilla torques it. The side of the cap has an O-ring around it that seals it around the sides before the cap is screwed in all the way, so the cap only needs to be screwed in until it stops. It's not going to vibrate out. So that is all the definitely good stuff. Now I'll mention one thing that could have been done better. The eye piece has a focus ring and it works well although it is "skinny", so you have to rotate it with your finger tips around the very outside rearmost part of the rangefinder and look through it at the same time to get it in focus. This means that you probably won't have your eye as close to the eyepiece as you would like while turning the diopter because your fingers are, at that point, acting like a spacer between the eyepiece and your face or your glasses. I wear glasses, so when I'm doing this my glasses are pressed against my two fingers instead of the eyepiece itself. It sounds like a big problem, but it doesn't keep me from getting it in perfect focus quickly since I'm used to it now. And once it is in focus, it stays in focus unless I push the eyepiece hard against my glasses and actually rotate the rangefinder. That only happened the first day I started using it. My vision changes as the day goes on, so I do fine-tune the focus a couple of times a day. My eyes are old. Some of you might wonder if the eyepiece scratches or leaves "rubber marks" on my glasses. Nope. Not at all. I don't know what kind of rubber or rubberized plastic or whatever the eyepiece is made of, but it's not the real grippy black stuff. It has kind of a greyish color to it and it always feels dry. OK, so more about the eyepiece. With my glasses pressed all the way onto the eyepiece I cannot see totally to all edges of the view -- close, but not quite all at once. So my glasses keep my eye from being able to get all the way as close as would be perfect. However, this in no way keeps me from being able to see the target and the aiming reticle and range targets easily and comfortably and in perfect focus. For those of you that do not wear glasses, note that this rangefinder does not have a spacing ring that would allow you to adjust the distance between your eye and the eyepiece. Maybe someone else that doesn't wear glasses will post a comment about their experience with this or other similar optics. I don't use the GUN mode, so I can't comment on it. I don't mind that it's there if I want to try it. This is the only Amazon review I've ever posted. I don't sell stuff and I'm not in any affiliate program. The only reason I decided to write this is because for the current price of $250 it seems like there would be more reviews on the Prime 1800 from real users.
