Mileseey IONME2 Golf Rangefinder Review: An Excellent Little Laser, but for a Specific Type of Golfer

Just a couple years ago, I hadn’t tested a single pocket-sized rangefinder.

Now, the Mileseey IONME2 makes three. And it might be the best-built and most feature-packed of the bunch. It’s also the most expensive, the one from the least-known brand, and the pickiest about who it’s actually for.

What I’ve found, now after a couple of rounds with the IONME2, is that this rangefinder is easy to love, fun to talk about and show off, but a little bit hard to figure out whether or not you should buy it.

This is a rangefinder that does things no similar product can do. For starters, it actually reads the distance of your putts on the green. Crazy, right? The question is, how valuable is that and would you actually ever use it?

Let me share my hands-on Mileseey IONME2 golf rangefinder experiences, because even if you don’t buy this laser, I think you’re going to find it interesting and you’re definitely going to want to know about this brand.

One More Device to Convince Me I Love Little Rangefinders

The Mileseey IONME2 golf rangefinder is small. That’s its most obvious feature. And it is a feature. At least I think so. I’ve come to thoroughly appreciate and enjoy playing golf with the convenience of keeping your rangefinder in your pocket without compromising or interfering with your swing.

But what’s a little strange, at least to me, about the IONME2 is that while it does easily fit in your pocket, that’s not actually how it’s designed to be carried.

This laser comes with a belt clip. It’s designed so that you magnetically attach the rangefinder into this holster that’s clipped to your belt, and that’s how you’re supposed to play.

I’m sorry, but for me, that was a hard no. I don’t claim to have much sense of style, but this kind of look just isn’t quite aligned with whatever “look” I’m aimlessly trying for. I just couldn’t get comfortable with the feel or appearance of having my rangefinder clipped to my belt. Nah.

I’m all about in the pocket. But I don’t get the included clip thing at all. I’ve seriously never seen anyone use a rangefinder that way.

And, I guess because it comes with the clip, you don’t get a carrying case of any kind with the IONME2. I’d definitely rather have the case than the clip myself.

I will say the magnet on this thing is crazy strong. It honestly might be in the same class as the Bushnell BITE magnet. So when you do want to ride with the IONME2, attaching it to a cart post is extremely reliable.

Interestingly, the magnet is on the flat bottom side of this rectangular rangefinder. I’ve never really seen a rangefinder with that shape or magnet placement.

One thing to watch out for: This rangefinder is very stealth. Because of its size and its black-and-gray colorway, it’s very, very easy to glance past.

I know everyone always talks about leaving their rangefinder stuck to the cart post. But I’ve gotten good at training myself not to make that mistake. And yet with this rangefinder, I did exactly that. Had to go back to the pro shop an hour after I played to retrieve it.

Which of course prompted a conversation regarding what this rangefinder is and what all of its features include and why it’s so small, etc. I’m telling you, this thing is a conversation-starter.

Anyway, I first learned with the Voice Caddie Laser FIT, then confirmed with the Bushnell A1-Slope, and now reaffirmed with the Mileseey IONME2 that small rangefinders provide a unique advantage.

I find it extremely convenient to be able to pull my rangefinder out of my pocket rather than having to pull it out of my bag or out of its case that’s clipped to my bag. It’s just faster and easier.

And because the IONME2 is less than 4 inches long, only about an inch wide, less than 2 inches tall, and less than 4 ounces in weight, I don’t find it cumbersome at all to swing a golf club with it in my shorts pocket. Now, in tighter-fitting pants or ones with smaller pockets, that’s probably not as good of a solution. But for playing in the summer, I love it.

But let’s look into what about the IONME2 makes it unique relative to the other pocket-sized options and how it compares to those competing products.

Build and Feel That Compete With Bushnell

If you’ve read any of my Bushnell rangefinder reviews, you know I almost always make some comment about how well they’re built. I’m not the only one. Pretty much everyone agrees that Bushnell is the standard when it comes to rangefinder build quality.

And when it comes to the other pocket-sized rangefinder comparison I’ve made, between the Voice Caddie Laser FIT and the Bushnell A1-Slope, one of the areas where the A1-Slope crushed the Laser FIT was in build quality.

Well, this Mileseey IONME2 golf rangefinder actually keeps up with the Bushnell standard. This thing is very solid.

It’s different from a Bushnell, or any other rangefinder, in that the shape is rectangular. So the handfeel is unique. But it's robust-feeling and seems like it could survive some hard falls, just like a Bushnell and far better than the cheaper, plasticky feel of the Laser FIT.

The Mileseey IONME2 Golf Rangefinder Is Incredibly Fast

This might be the fastest rangefinder I’ve tested since the Voice Caddie TL1. I mean, it’s pretty much instantaneous feedback with the IONME2. Mileseey rates it at 0.1 seconds from button to number. I can’t stopwatch that, but I’ll say again that you press the button and you get the number faster than you can think about it.

I also really like the way that this laser gives you feedback. A lot of rangefinders are all-or-nothing in that they lock onto anything and everything and give you the same visual and haptic feedback every time. The IONME2 is much more trustworthy because it offers the feedback kind of in levels.

If you get a number without a buzz, that’s the rangefinder being a bit unsure of what it’s ranging. Then if you get a buzz but don’t get a green ring around the bullseye in the viewfinder, that’s like the next level of confidence but still without certainty. Then when the rangefinder knows for sure it’s locked onto a flagstick, you get a very confident strong vibration plus the green ring in the viewfinder.

I’ve really found that this rangefinder eliminates second guessing for me. It may seem like a small thing, but I really like getting this layered feedback response.

Mileseey IONME2 Golf Rangefinder Optics and Display

The glass on this rangefinder is excellent.

Magnification is 6x, which is standard for the category and the same as you’ll find on both the Laser FIT and A1-Slope. But the view on this IONME2 is exceptionally clear. It’s sharp and bright, and there’s no distortion on the edges.

The viewfinder is a touch smaller than what you get on a full-size laser, of course, but the clarity inside is up there with anything I’ve looked through in the mid-tier rangefinder class.

And the display is where the IONME2 pulls ahead of the other pocket rangefinder options. It’s a dual-color OLED that shows your numbers in red and green, with brightness that adapts to your lighting.The display quality actually reminds me a lot of the Bushnell Tour V7 Shift, which is a laser I really love.

The Laser FIT uses a dual-color LED that flips between black and red depending on the background, and that’s a nice feature for the price. But the IONME2’s OLED is a step up. The red and green contrast is fantastic, the numbers pop against any backdrop, and it just looks more premium.

Alright, now let’s get into the things that make the IONME2 truly interesting.

Understanding the IONME2 “Coach Mode”

Mileseey calls it Coach Mode, which I find odd. I call it triangulation. By whatever name, we’re talking about the ability to stand in one spot and measure the distances between two other points. Shoot your ball, then shoot the pin, and the IONME2 does the math to tell you exactly how far your ball is from the target, even when you’re nowhere near your ball.

On a cart-path-only day, when your ball is sitting on the far side of the fairway from the path, you can get your real number without having to guess and carry a bunch of extra club options with you.

Blind shots are another scenario where this feature really comes in handy. You can step around to a place from where you can see both your ball and the pin and then get the distance you need to carry maybe some bushes or trees that are between your ball and the green.

I also use this regularly to help playing partners with yardages. You can just pull out the rangefinder, shoot their ball and then the pin and yell their number to them. I guess maybe that’s how Mileseey came up with Coach Mode as their name for this feature. I still find that one strange.

Regardless, it works great on this rangefinder. I tested it by shooting triangulated distances and then confirming them with direct point-to-point measurements, and the calculations were correct every time.

Triangulation is a big deal. And a rare one. There are only a handful of rangefinders available that do this. Interestingly, the Voice Caddie Laser FIT, another one of the pocket-sized options is one of them, and it’s a couple hundred dollars less, which is a bit of a teaser for the pricing challenges I think the IONME2 faces. More on that in a moment.

The Green-Reading Mode Is… Interesting

This is the part that is definitely different from your standard rangefinder experience. In fact, it’s the first time I’ve ever used a feature like this.

With the IONME2, you can actually use your rangefinder on the green to read your putt lengths.

Now, your first reaction to that sentence may be your best instinct as to whether you’ll find this feature beneficial.

If you think the idea of pulling a rangefinder out on the green is ridiculous, well, this might not be quite right for you.

If you think it sounds interesting or kind of cool or potentially really useful, I don’t know how you say no to the IONME2.

The way it works is, you calibrate the green-reading function by inputting your height into the rangefinder during setup. Then, on the course, you click a button to enter the green mode and then you laser the top of the flagstick. From there, you get the distance of the putt in feet.

Now, I have to say, the amount of sh*t that I would catch from my playing buddies if I pulled a rangefinder out on the green is almost immeasurable. 

That said, when I’m on my own, or when I’m practicing, or if maybe I grew some thicker skin and decided that I really didn’t give a damn, it’s actually quite cool.

I legitimately enjoyed being able to laser the distance on my long putts. And where I can envision it being useful is in practicing. Many of us pace off our lag putts. This rangefinder feature kind of allows you to lock a distance to your pacing estimate system and therefore better calibrate it. You can get a better handle on how many paces it is for say a 30-foot putt, and by marrying all of that information, I think it could really actually help you become a better lag putter.

In any case, it’s accurate. I confirmed it with a tape measure.

Whether or not you’ll ever use something like this, I think you’re going to have to decide that.

The problem, I think, is that if you’re not going to use a feature like the putt distance reading or the triangulation, or especially if you don’t care about the pocket-friendly size, I think the IONME2 may be a bit too expensive. Let’s look closer.

It All Comes Down to the Mileseey IONME2 Price

Let’s add it up.

The Mileseey IONME2 golf rangefinder gives you a premium build that keeps up with Bushnell, excellent optics, a beautiful dual-color OLED display, incredible speed, a pin-locking system I love, triangulation, a green-reading mode, and you can fit it in your pocket. Or clip it to your belt.

That’s a seriously loaded little laser.

Then you look at the price tag. It’s $399.99. And I think that’s where it gets complicated.

The Bushnell A1-Slope is $299.99. It’s pocket-sized. It’s got great build and optics. And, probably most importantly, it’s Bushnell. Most people are much more likely to trust that brand than Mileseey, which very few have even heard of.

So is the IONME2 worth $100 more than the A1-Slope? Well, it comes down to triangulation and the green-reading mode. Those are the main things that the IONME2 does that the A1-Slope doesn’t.

For a lot of golfers, those two features aren’t worth a hundred bucks.

But if you happen to be looking for those unique differentiators or think you’d really appreciate them, then a hundred bucks extra probably doesn’t feel too severe at all.

There’s also the Voice Caddie Laser FIT, which you can generally find for about $200. And it does include triangulation. In fact, when I tested it, I liked it a lot. But the Mileseey is much better built, and the optics are far better. I don’t know if it’s worth twice as much, but it’s definitely a much nicer product.

I think it’s a bummer that you don’t get a case with the IONME2.  And, personally, I don’t have any use for the belt clip.

But I love the size, I love the build, and I’ve actually come to appreciate the unique features that I may have previously dismissed as quirky, much more than I expected to.

This is a very cool rangefinder. I’m just not sure enough people are going to think it’s cool enough to spend $400.
