COALAX RANGER In-Depth Review | A Hiking Pack with a Camera Arm That Films You Even on a Chain Section

2026.05.12

I usually go into the mountains with a camera operator. Even so, there are plenty of moments where I want myself in the footage, and for those I've relied on a selfie stick. The problem is that on a chain section or a steep climb there's no spare hand to hold one, so there are always shots I want and can't get. That small frustration has been with me for a long time.

What solved it, unexpectedly, was the COALAX RANGER: a hiking backpack with a camera arm built into it. Let me start with the conclusion. This is not a lightweight pack for everyone. It weighs 3 kg on its own, and it isn't cheap. But for anyone who refuses to give up on filming themselves in situations where both hands are occupied, it may genuinely be the only option — neither a selfie stick nor a tripod. Below I go through what the arm and the pack can do, and then five things I honestly think you should know before buying.

The frustration I'd been carrying

As I said, I'm usually in the mountains with a camera operator, but I shoot as well. When I want an angle they can't cover, or a shot with me as the subject, the selfie stick has been the tool.

Selfie sticks have limits, though. Your arm is in the frame, and you're basically stuck with a front-on angle. Above all, in places where you need both hands — chain sections, steep rock — you simply can't hold one. You want the shot, and safety says no. That loop repeated itself for years.

Then a review request for the COALAX RANGER arrived. The moment I saw it, my instinct was that this would land hard with hikers who want themselves in their own footage. There was almost nothing in Japanese covering it in detail, so I've tried to be as thorough as I can. The version I was sent is the "Outdoor Bundle," which includes the magic arm and a chest bag.

What the camera arm can do — 1.5 m of reach, 360°, and a third-person view

The defining feature is obviously the camera arm built into the pack. Here's what it does.

Features

• The arm extends to 1.5 m. It can film you from behind and above, which produces footage that looks as though a separate camera operator is walking with you.
• It rotates 360° — horizontally, vertically and at any angle in between. Side-on, directly behind, low angle: you can set whatever framing you want.
• Cameras mount on a 1/4-inch thread, the industry standard, so almost anything works: a camera, an action cam, even a phone holder.
• With the arm stowed, standing the pack on the ground turns it into a tripod. Useful for self-timer shots and group photos, in a quiet way.
• Setup is fast, so when you decide you want a shot, you can have it framed immediately.

One caution: the arm's locking screws are plastic, and over-tightening can break them. Two fingers until it stops firmly is the right amount. Worth remembering.

There's also an optional configuration with a large battery and a solar panel, which I haven't tried. Being able to charge a camera or phone while walking would be an appealing bit of expandability if you shoot over multiple days.

How good is it as a backpack? 31 L, exoskeleton frame, IPX5

You might reasonably wonder whether a pack built around a camera gimmick treats the carrying part as an afterthought. Having worn it, the answer is no — it's put together properly as a hiking pack.

Features

• Up to 31 litres of capacity. A jacket, water bottle, snacks and camera accessories all went in with room to spare.
• An exoskeleton back frame that transfers load onto the hips effectively.
• A ventilated mesh back panel, so it doesn't get too clammy over a long day.
• A removable waist belt you can take off when you don't need it. The carry position also adjusts across two settings for torso length, which makes fitting it to your body easier.
• IPX5 water resistance. In light rain you can keep walking without a rain cover (though I have an honest caveat about this further down).
• Hidden "kangaroo" pockets at the top and at the waist. The top one is the right size for a rain shell; the waist one will actually swallow a helmet.
• Fully modular MOLLE panels, so camera gear can be mounted on the outside.
• Inside there's a laptop sleeve that takes up to 16 inches, which makes it usable in town and while travelling.

The Outdoor Bundle also includes a chest bag. Used together with the pack, it holds the things you reach for often so you can get at them without taking the pack off. On a mountain that turns out to matter more than it sounds.

Using it in the field — hands free on the chains of Iyogatake

Now the part that counts: using it out there. We filmed on Mt. Iyogatake in Chiba Prefecture, which has chain sections.

What it was like

The first thing I noticed was how different it is from a tripod. A tripod costs you one or two minutes every time — find a spot, open it, set it — and then you're anchored to where you put it. The RANGER, by contrast, is already on your back and you just walk. On a mountain that difference is enormous.

The second thing, the moment we set off, was the simple sensation of having my hands free. Obvious, perhaps, but on a mountain it matters hugely: the stress of moving over rock while holding a camera disappears completely.

The moment that really got me was watching the footage back afterwards. Filmed from behind and above by the arm, I was the subject standing in the landscape — exactly as if a third person had been filming me. With a selfie stick your arm is in shot and you only get your face from the front. The gap is not subtle.

And then there was the shot that a selfie stick makes flatly impossible: the chain section on Iyogatake. On rock where both hands are occupied, there's no holding anything else. Normally you either give up on filming or ask someone. With the arm, the camera keeps rolling, and because my hands were free I could grip the chain properly. You can take the risk seriously and still not abandon the footage. That's the problem this thing was actually built to solve. Honestly, I suspect that single scene on the chains is enough to justify ¥56,000 for a fair number of people (check the video description for the exact price and current availability).

At the summit I got a shot I loved without a tripod or a self-timer. Even though I usually work with a camera operator, my honest reaction was surprise at being able to record myself like that without anyone's help.

Five things I'd want you to know

A review that only lists the good parts isn't a review. Here are five things that stood out to me in use.

1. Be aware of the exoskeleton frame. If you fall backwards, the frame can make contact with your back. Keep that in mind on steep rock or slippery routes. 2. Weight. The pack alone is 3 kg. Anyone chasing a light setup will find that too much, and combining it with a long route or heavy overnight camping gear is, honestly, hard work. 3. Don't over-trust the water resistance. IPX5 it may be, but the seams aren't taped. Seams naturally hold water, and in sustained rain the pressure can push it through. If you're carrying a camera or other sensitive kit, use a rain cover when heavy rain is likely, or bag the gear individually in ziplocks. 4. The arm takes up space. Extended, it has real presence around you. On a crowded summit, a narrow ridge or a busy trail where people pass each other, fold it away or be considerate. 5. Price. Check the description for the current figure, but as a backpack alone it is expensive. Viewed as a filming system that happens to carry your gear, though, it can be a reasonable investment for someone who's been looking for something that isn't a selfie stick or a tripod.

Who it's for

Based on all of the above, here's who I think this lands with.

Worth considering if you

• Want yourself in your footage, including angles a camera operator can't cover
• Don't want to give up filming on chain sections or steep climbs where both hands are busy
• Have been uneasy about how unstable, and how unsafe, a selfie stick can be

Probably not for you if you

• Are chasing minimum weight (3 kg is heavyweight territory)
• Regularly walk long distances with already-heavy loads such as camping gear

Final thoughts: not perfect, but hard to replace

The COALAX RANGER is not a perfect pack. Three kilograms, untaped seams, the price — there are several things I'd flag honestly.

What it does have is a genuine answer to a problem no other tool solves. It isn't a selfie stick and it isn't a tripod, and it has retired years of "I can't film this because my hands are busy." If you love the mountains, want yourself in the record, and have been uneasy about having no hands free — this is the one I'd want you to hear about.

On this channel I say what was good and what was underwhelming, as I found it. I hope your next day out, and your next set of footage, is freer and safer for it.
