Most gear reviews focus on microphones, mixers, and cables — the stuff that makes sound. The Hercules DG307B tablet holder doesn’t make any sound at all, but it’s one of the pieces of gear I depend on most at every single gig.
I’ve been gigging for over 30 years across multiple bands. These days I play in a five-piece rock band running a fully digital live rig, and between the band members we run five Hercules DG307B units on stage at every show. Personally I use two of them — one holding an iPad for click tracks and one holding a Fire tablet for mixing in-ear monitor mixes on the fly. The other band members have adopted them for their own tablet setups over time, which is probably the most honest endorsement I can give: once you try one, you don’t go back to anything else.
This Hercules DG307B review covers what makes it the best tablet holder for live performance, who it’s right for, and why it’s the only tablet mount I’d recommend for serious gigging.

How We Use the Hercules DG307B at Every Gig
Context matters in a product review, and ours is specific: we’re a five-piece rock band running a fully digital live rig centered around the Behringer XR18. The XR18 is controlled via tablet — no physical faders, no dedicated engineer at a board. Every channel adjustment, every monitor mix tweak, every scene change happens on a screen. With five band members all running their own tablet-based setups, having a mount that’s reliable and consistent across the whole band matters.
Our first DG307B holds an iPad running click tracks and backing track playback for the drummer. It’s mounted on a mic stand at his position, angled for easy visibility, and stays locked in that position through an entire show without drifting. He can glance at it between songs, tap the screen to advance to the next track, and trust that it’ll be in exactly the same position when he looks back at it. That reliability matters during a performance.
Our second DG307B holds a Fire tablet running the Mixing Station app for in-ear monitor mixing. During soundcheck and the first few songs, I use it to fine-tune individual IEM mixes for each musician — pulling up a specific channel, adjusting the level, moving to the next musician’s mix. The holder keeps the tablet at the right height and angle for quick, confident adjustments without looking away from the stage for longer than necessary.
Five units across the band, two of them mine, all doing different jobs — the same result: stable, reliable, no drama. That’s the whole review in one sentence, but let me break down why.
For more on the XR18 setup this integrates with, see my Behringer XR18 review and my guide to setting up in-ear monitors for small bands.
Build Quality: Built for the Stage, Not the Desk
The DG307B is immediately recognizable as a piece of Hercules gear — the same company that makes mic stands trusted by working musicians worldwide. The construction is metal where it matters, with adjustable arms that grip the tablet through silicone-lined contact points that protect the device while holding it firmly.
The mic stand clamp is the foundation of the whole unit. It threads onto a standard mic stand thread and locks down with a secure locking ring. Once tightened, it doesn’t move. Not a little, not gradually over the course of a show — it stays exactly where you set it. The friction adjustment on the tilt mechanism holds the chosen angle through vibration, accidental bumps, and the general movement of a live stage without drifting.
The extending arms accommodate a wide range of tablet sizes — from small tablets and large phones up to full-size iPads and 10-inch tablets. The adjustment mechanism is simple and intuitive: open the arms, place the tablet, close the arms to grip. No tools, no fiddling, no complicated locking mechanisms. It takes about ten seconds to mount or remove a tablet, which matters when you’re loading in and out quickly.
After years of regular use — repeated setup and teardown, transport in gear bags, occasional bumps and knocks — both of our DG307B units show normal wear with zero functional degradation. The clamp still locks firmly, the arms still grip securely, the tilt still holds its angle. That’s the definition of road-worthy gear.
Stability: The One Thing That Actually Matters
Every tablet holder claims to be stable. Most of them aren’t — not under the real conditions of live performance. A tablet that shifts position during a show, drifts out of its set angle, or vibrates noticeably from stage movement is more of a distraction than a tool.
The DG307B’s stability in practice is genuinely excellent. Mounted on a standard mic stand, it holds position through everything a live stage throws at it — floor vibration from bass and kick drum, people moving around nearby, the general bumps and adjustments of a busy stage setup. The tablet doesn’t drift, the angle doesn’t creep, and the whole assembly feels planted rather than perched.
This stability is what separates it from cheaper alternatives. Budget tablet mounts use plastic clamps that compress and loosen over time, friction mechanisms that can’t hold a set angle under vibration, and arm springs that weaken after repeated adjustment. The DG307B uses metal construction and a properly engineered friction system that maintains its settings through years of use rather than weeks.
Compatibility: Works With Everything
One of the practical strengths of the DG307B is its universal compatibility. The extending arms accommodate tablets from roughly 5.9 inches to 13 inches in width — which covers virtually every tablet and large phone currently available. We’ve used it with an iPad, a Fire tablet, and tested it with a Samsung Galaxy Tab, all without any fit issues.
The mic stand clamp fits standard 5/8-inch threads which is the universal standard for mic stands worldwide. If you have a mic stand — any mic stand — the DG307B will mount to it. The clamp also works on round tubing of similar diameter, which covers boom arms, keyboard stand tubes, and other common stage hardware.
The 360-degree rotation and adjustable tilt give you essentially unlimited positioning options. Landscape or portrait orientation, angled toward the performer or angled toward the audience-facing position, tilted for glare reduction under stage lighting — it accommodates every scenario without requiring any additional hardware.
Real-World Workflow Benefits
Beyond the hardware, the DG307B changes how you work on stage in practical ways that are easy to underestimate until you’ve used it.
Having a tablet at a fixed, accessible position means you make adjustments confidently rather than tentatively. When you know the tablet will be in exactly the right spot when you reach for it, you reach for it without hesitation. When it’s balanced awkwardly in one hand while you try to adjust with the other, you avoid touching it unless you have to. That difference in workflow confidence is real and cumulative over a show.
For digital mixer users, this is particularly significant. The entire value proposition of a mixer like the XR18 is that it puts the full mixing workflow in your hands via tablet. A poor tablet mount undermines that workflow. The DG307B completes it — the tablet is always where you need it, at the angle you need it, ready for the next adjustment.
For bands running click tracks or backing tracks off a tablet, the same principle applies. The drummer needs to glance at the screen at a predictable position, not hunt for it. The DG307B puts it there and keeps it there.
If you’re running a fully digital stage setup, keeping your whole signal chain organized — cables, devices, and mounts — is part of what makes shows run smoothly. See my guide on how to run cables on stage for how we keep everything tidy alongside gear like this.
How It Compares to the Alternatives
I’ve tried other tablet mounts before landing on the DG307B as our permanent solution. The pattern was consistent: budget mounts from generic Amazon brands look adequate in photos and fail in use. Plastic clamps loosen, friction mechanisms can’t hold angles under vibration, and the arm springs that grip the tablet weaken after a few months of regular adjustment.
The iKlip series from IK Multimedia is the closest legitimate competitor — well-built, designed for musicians, and trusted by working performers. It’s a valid alternative, particularly for specific tablet configurations. Where the DG307B wins is in universal tablet compatibility and the simplicity of the adjustment mechanism. The extending arms of the DG307B accommodate more tablet sizes more easily than the iKlip’s configuration-specific designs.
On-Stage tablet mounts are a decent budget step up from generic options but still fall short of the DG307B’s build quality and stability in sustained live use. For occasional use or lighter applications, they’re adequate. For regular gigging where the mount is part of every show’s setup, the DG307B’s durability advantage compounds over time.
Who the Hercules DG307B Is Right For
The DG307B is the right choice for any musician who uses a tablet as part of their live performance workflow. That covers more gigging musicians than ever — digital mixer users, click track runners, backing track players, and anyone who needs a device mounted securely at a specific position on stage.
It’s particularly valuable for bands running digital mixer setups. If your live rig includes an XR18, X32, or any other tablet-controlled digital mixer, the DG307B is the mount that completes that setup. See my digital vs analog mixers guide for more on why tablet-controlled digital rigs have become the standard for small bands.
It’s also right for solo performers who need a setlist, chord chart, or backing track app mounted at eye level without occupying a hand. The stability and quick tablet mounting make it practical for any performance context where a device needs to be accessible and secure.
Final Verdict: Hercules DG307B Review
The Hercules DG307B is the best tablet holder for live performance I’ve found after years of gigging with tablet-based setups. It’s stable, durable, universally compatible, and simple to use in the conditions that matter — repeated setup and teardown, live stage vibration, quick adjustments during a show.
We run two of them at every gig and have for years. That’s the most honest recommendation I can give: it’s not gear I reviewed once and moved on from. It’s gear that’s become part of our permanent live rig because it works, show after show, without asking for attention.
If you use a tablet on stage in any capacity, the DG307B is the mount worth buying once rather than replacing budget alternatives repeatedly.
