The Flux Pro is a steel tip set from Harrows’ autumn and winter 2026 range, launched alongside the Torrent. It is a long, parallel barrel in a natural tungsten finish, with Harrows’ Quick Point system for swapping tips and the Solo integrated flight and shaft fitted out of the box.
Harrows sells it under its Pro Tungsten name but does not publish a tungsten percentage for it, so we have left that figure out rather than guess.

How They Compare
Spec sheets mean more next to the alternatives. Here is the Flux Pro against three similar darts we have covered, using the figures each manufacturer publishes.
| Flux Pro | Target Buzz (opens in a new tab) | Sable (opens in a new tab) | Javelin (opens in a new tab) | |
|---|---|---|---|---|
| Price band | Moderate | Moderate | Moderate | Value |
| Tungsten | Not published | 90% | 90% | 85% |
| Weights | 22g, 23g, 24g | 22g, 24g, 26g | 21g to 26g (by shape) | 20g to 26g |
| Barrel length | 54mm | 50.5mm | 50.8mm (Parallel, Torpedo) | 54.6mm |
| Barrel diameter | 6.65mm (22g) | 6.5mm (22g) | 6.60 to 6.85mm (Parallel) | 6.15mm (20g) |
The Flux Pro is over 3mm longer than the Buzz and the Sable, the other two quick-swap darts here. Only the Javelin matches its length, and that one has fixed points.
Who They Suit
| If you... | Fit | Why |
|---|---|---|
| Like a light, slim dart | Partial | Lightest is 22g with a 6.65mm barrel |
| Want a thick, heavy barrel | Partial | Heaviest is 24g at up to 6.9mm |
| Want grip cuts along the whole barrel | Good | Harrows describes the grip zone as full length |
| Prefer a short barrel | Poor | Barrel length is 54mm |
| Want quick-swap points | Good | Quick Point tips swap with the included tool |
| Are working to a tight budget | Partial | It sits in the Moderate price band |
The weight range stops at 24g, so anyone throwing 25g or heavier needs a different dart. If you want a long barrel for less money and can live without swappable points, the Red Dragon Javelin runs 54.6mm in the Value band. For a quick-swap dart of a more usual length, the Target Buzz and Red Dragon Sable both sit in the same price band.

What Owners Say
There is no reception to report yet. The Flux Pro first appeared on sale in October 2026, and when we checked, Harrows’ own product page, a major UK darts retailer and the main marketplace listing all showed no customer ratings. We could not find an independent written review either.
We will add owner feedback here once there is enough of it to say something useful. Until then, treat anything you read about how it throws as a first impression rather than a consensus.
The Grip: What to Expect
Harrows rates the grip 3 out of 5, which is medium. The cuts are a mix of fine micro rings and wider scalloped grooves, with a few dark bands between them, and they run the whole length of the barrel rather than stopping at a smooth section. Harrows describes the result as forgiving and consistent.
The packaging tells a slightly louder story, with a “high traction grip” badge on the spec sheet below. Go by the numeric rating. A full-length medium grip gives your fingers something to find wherever you hold a 54mm barrel, without the bite of a heavily cut dart. No owner has reported on it yet, so if grip matters most to you, handle a set before you buy.
The Consensus
There isn’t one yet. On paper the Flux Pro offers something the site’s other quick-swap darts in this price band don’t: a 54mm barrel. The trade-offs are visible from the specs alone. Weights stop at 24g, Harrows doesn’t say how much tungsten is in it, and the integrated Solo flights mean replacing flight and shaft together when one breaks. If the length is what draws you, it is worth a look, but you are buying ahead of any owner verdict.
How we compile this page
We don’t throw every dart ourselves. Instead we gather the manufacturer’s published specifications and weigh up the reception from owners and independent reviewers, then flag where they disagree so you can make up your own mind. Where a headline rating comes from manufacturer-hosted reviews, we say so, because those tend to skew positive.
