The Sonik SKS2 is a mid-range wireless bite alarm set that punches well above its price bracket on almost every front, combining a dependable roller wheel sensor with a 150 m wireless range, drop-back indication, vibro mode, colour-sync LEDs, and a wireless bivvy light straight out of the box.
It is one of the most feature-complete sets available for under £200, and the bundled bivvy light alone sets it apart from the majority of rivals at this level. We put this model through its paces as part of our wider bite alarm comparison. The SKS2 covers the kind of ground that most anglers would expect to pay significantly more for.
Six tone options with automatic sync, four sensitivity levels that trigger on as little as 5 mm of line movement, a dedicated drop-back LED on the receiver, and a 20-second latching channel LED all add up to a setup that is genuinely difficult to fault at this price point.
The design shares some visual DNA with the Fox Mini Micron X, but the SKS2 brings considerably more functionality to the bank. The one notable absence is an anti-theft alarm, a feature Sonik does offer within the same family on the Gizmo2 for those who need it.
Batteries are also not included for any of the three components, which is worth noting before your first session.
For anyone shopping in the sub-£200 bracket, the SKS2 makes a compelling case from the off.

Editorial Review: Our Opinion On The Sonik SKS2 Bite Alarm
Bite Alarm Type / Range / Type of Motion Sensor / Accessory Compatibility
The Sonik SKS2 is a wireless bite alarm set running a roller wheel sensor, a range of up to 150 m, and accessory compatibility that includes a wireless bivvy light straight out of the box. Capable kit that covers all the bases and then some.
The SKS2 works as a dedicated wireless bite alarm, firing every signal from the alarm head directly to your receiver the moment a fish moves off with the bait. Whether you’re watching the rods or flat out in your bivvy, any take gets picked up without delay.
Bite detection runs through a roller wheel, the tried and trusted mechanical option that has earned its place on the bank through years of dependable service. Roller wheels hold a clear edge over optical sensors in the conditions that matter most.
Thick fog, heavy condensation, and rain-soaked nights are exactly the scenarios where optical alarms start throwing false bleeps or missing takes altogether. A roller wheel keeps turning regardless, which is a genuine reassurance when you’re fishing through a murky autumn night or riding out a proper downpour on the bank.
The 150 m wireless range gives you a comfortable working distance between your alarm heads and the receiver. In open conditions with a clean line of sight, that figure holds up well and leaves plenty of room for larger swims or a bivvy pitched well back from the water’s edge.
Bankside obstacles and dense vegetation will eat into that range as they do with any wireless system, but 150 m is a strong starting point that puts the SKS2 ahead of several alternatives sitting in a comparable price bracket, including the Prologic BAT+ at 100 m and the JRC Radar DR at 120 m.
On the accessories front, the SKS2 arrives with a wireless bivvy light already in the package, so camp integration is sorted from day one without any additional outlay. For anglers who want a fully connected setup straight away, that bundled light makes the SKS2 a compelling choice that is difficult to overlook at this level.
Special Indication for Drop-Back Bites / Latching LED / Receiver with Vibrate Mode / Night Light
The SKS2 covers drop-back bites in both directions, runs a colour-sync LED system across alarm and receiver, offers vibro mode on the receiver, and features a night glow LED function for visibility in the dark.
Drop-back indication on the SKS2 works in both forward and backward directions, so a fish moving toward you rather than away gets flagged just as reliably as a standard run. The alarm tells the two apart without any guesswork on your part: a normal run triggers both LEDs solid alongside a standard tone, while a drop-back fires the LEDs in a blinking pattern paired with a lower tone.
On the receiver, a dedicated white drop-back LED flashes separately, so even across the bivvy there is no chance of mixing up the two signals. The channel LED on the receiver stays latched on for 20 seconds after a take, giving you a clear window to clock which rod has a fish on before the indication clears.
That 20-second hold is long enough to get your bearings without the display hanging on indefinitely. The night glow LED function adds a low-brightness background illumination to the alarm head in whatever colour you have selected, making it straightforward to locate your alarms on a dark bank without having to fumble around with a torch.
Vibro mode on the receiver is a solid addition for anglers who prefer to keep noise to a minimum, whether that is fishing a busy venue, sharing a bivvy, or simply running a quieter setup overnight. It keeps you in the loop without broadcasting every bleep to the next peg.
Volume / Sensitivity / Tone / Anti-Theft Alarm
The SKS2 gives you six volume levels, six tone options, and four sensitivity settings. An anti-theft alarm is not part of the package, but for anglers who want that feature without jumping into premium territory, Sonik has a compelling answer within its own lineup.
Volume runs through six settings with a silent mode at the bottom end, covering everything from a quiet overnight session to a windswept open bank where you need the alarm to cut through the conditions. Six tone options let you set each rod apart by sound alone, which makes identifying which alarm has fired straightforward without having to check the receiver every time.
The selected tone syncs automatically across the receiver and the bivvy light, so the whole setup speaks the same language the moment a fish moves off. Sensitivity runs across four levels, with the highest setting triggering on as little as 5 mm of line movement.
That kind of fine-tuning matters when you are fishing slack lines or dealing with a cautious fish that barely moves the bait before dropping it. On the anti-theft front, most alarms only pick this feature up once you are well into premium territory, typically north of £500, where you find it on sets like the Nash Siren R4 and the Delkim Txi-D v2.
Sonik has a reputation for punching well above its price point, and that shows in the Sonik Gizmo2, which brings anti-theft detection to a mid-range price bracket without asking you to stretch your budget anywhere near those premium figures.
Batteries Required / Box Contents
The SKS2 set runs on AAA batteries throughout: two per alarm head, two for the receiver, and three for the bivvy light. None are included in the box, so worth picking up a pack before your first session.
Each alarm head takes two AAA batteries, as does the receiver, keeping things consistent and easy to manage on the bank when you need a quick swap in the dark. The bivvy light requires three AAA batteries, which is worth noting separately so you are not caught short on your first trip out. On the box contents front, the SKS2 arrives as a complete ready-to-fish package.
The bundled bivvy light rounds things off neatly. It can be triggered automatically when an alarm fires or switched on manually, runs across six colour channels, and offers four brightness levels alongside six delay modes.
Attachment is handled by either a magnetic fitting or a hook mount, so getting it positioned inside the bivvy takes no time at all. For anyone who has priced up a separate wireless light recently, having one dropped straight into the box at this price point is a genuine bonus that is difficult to overlook.
What Owners Are Saying: A Customer Review Round-up
At the time of compiling this review, we analysed more than 10 verified customer ratings. The Sonik SKS2 achieved an average score of 4.2 out of 5 stars.
Below is a curated selection of feedback from anglers who use this tackle:
- Excellent quality, straightforward to use, great value, and a clean modern look.
- Very good set overall.
- Hard to beat for the money. One of the strongest options on the market at this price point.
- The receiver stopped working shortly after purchase.
- Clever design and well thought out. The wireless bivvy light is a standout addition as it saves you rooting around for a head torch in the middle of the night.
- Had to return them to the shop as the alarm heads refused to sync up with the receiver. Even the staff could not get them to connect.
- Solid alarms. Been fishing the older version for years and these carry on where that left off.
The feedback from the angling community paints a broadly positive picture. Most buyers are impressed with the build quality, ease of use, and value for money, and the bundled bivvy light draws particular praise from anglers who appreciate having camp lighting sorted straight out of the box.
The nod to the previous version from a long-term Sonik user also speaks well of the brand’s consistency. A small number of buyers flagged issues, including a receiver that failed to function and a sync problem that even a shop could not resolve. These are isolated cases rather than a pattern across the review pool, but they are worth bearing in mind.
As with any electronic tackle, running a full function check at home before heading to the bank is always the sensible move. The Sonik SKS2 is a feature-rich wireless alarm set that punches well above its price point and delivers exceptional value for money.
The design shares some visual DNA with the Fox Mini Micron X, but the SKS2 brings considerably more to the table in terms of functionality, including vibro mode, night glow LED function, and a wireless bivvy light thrown in for good measure.
We align ourselves with the broadly positive customer consensus and award the Sonik SKS2 an editorial rating of 3.7 out of 5 stars, a figure that reflects the smaller review pool currently available rather than any reservation about the product itself.
For anyone shopping in the sub-£200 bracket, the SKS2 is one of the strongest options available right now, and we have no hesitation in recommending it as a top buy.
Sonik SKS2: Pros and Cons
As a mid-range wireless set that covers far more ground than its price suggests, the Sonik SKS2 delivers reliable bite detection, a comprehensive feature set, and a wireless bivvy light straight out of the box.
It stands out for its 150 m range, drop-back indication, vibro mode, and exceptional value for money, though the anti-theft function is absent and the review pool remains relatively small at this stage.
Pros
- Reliable roller wheel sensor unaffected by condensation or heavy fog
- 150 m wireless range, outpacing rivals like the Prologic BAT+ at 100 m and the JRC Radar DR at 120 m in the same price bracket
- Drop-back indication in both directions, with separate visual and audio signals to distinguish a run from a drop-back
- Six tone options with automatic sync across receiver and bivvy light for audible rod separation
- Four sensitivity levels, triggering on as little as 5 mm of line movement at the highest setting
- Vibro mode on the receiver for discreet bite indication overnight or on busy venues
- Colour-sync LED system across alarm heads and receiver for colour-coded rod identification
- Wireless bivvy light included in the box with six colour channels, four brightness levels, and six delay modes
- Sealed weatherproof housing with rod-friendly rubber inlays
- Outstanding value for money for a feature set that rivals alarms at significantly higher price points
Cons
- No anti-theft alarm, a feature available within the Sonik range on the Gizmo2
- Batteries not included for any of the three components
- Relatively small review pool at this stage, making the customer consensus harder to read with full confidence
- Isolated reports of receiver and sync issues straight out of the box
The Sonik SKS2 is a feature-rich wireless alarm set that punches well clear of its price bracket on almost every front. Drop-back indication, vibro mode, tone control, colour-sync LEDs, a 150 m range, and a bundled wireless bivvy light add up to a package that is genuinely difficult to match at this level.
The absence of an anti-theft alarm is the one obvious gap, and anglers who need that feature would do well to look at the Sonik Gizmo2 within the same family.
For anyone shopping in the sub-£200 bracket, the SKS2 makes a compelling case and earns a straightforward top buy recommendation from us.
Sonik SKS2: Frequently Asked Questions
Are the Sonik SKS2 alarms waterproof?
Sonik describe the SKS2 housing as sealed and weatherproof, and the set handles rain and spray throughout a normal bank session without any bother. The instruction manual does advise allowing the units to dry out properly indoors after use in heavy rain, so full submersion is not something the set is designed for.
For standard fishing conditions, the weatherproofing is more than adequate, but a bit of care near the water’s edge is still sound practice.
How do I pair the SKS2 alarm heads with the receiver?
The alarms in a new set come pre-registered to the receiver straight out of the box, so most anglers will not need to run through the pairing process at all. If you are adding an extra head or changing the registration order, switch on the receiver and hold down both the V and M buttons until the first channel LED begins to flash.
Turn on the alarm head you want to assign to that channel and the receiver will confirm the pairing. The next channel LED will then flash, ready for the following alarm. Once all heads are registered, hold both buttons again to exit registration mode.
What batteries do the SKS2 alarms, receiver, and bivvy light require?
Each alarm head runs on two AAA batteries, as does the receiver. The bivvy light takes three AAA batteries. None are included in the set, so it is worth picking up a pack before your first session. The consistent use of AAA batteries across the alarm heads and receiver is a practical touch, as it means you only need to carry one battery type for those two components.
Will the SKS2 alarms interfere with other anglers’ setups on a busy water?
The SKS2 operates on a 433 MHz AM radio frequency and uses a unique pairing code assigned to each set. Your receiver will only respond to its own registered alarm heads, so there is no risk of picking up signals from a neighbouring angler’s kit, even on a well-stocked day ticket water with multiple anglers fishing close together.
Can I connect illuminated swingers or drop-back indicators to the SKS2 alarms?
Yes. Each alarm head has a 2.5 mm power output socket on the underside, which is compatible with most illuminated swingers and drop-back indicators fitted with a 2.5 mm jack plug. This gives you an additional visual signal at the rod tip on top of the alarm’s own LEDs and speaker.
Can I use the SKS2 on rivers or venues with a strong current?
The four sensitivity levels give you a reasonable degree of flexibility here. Dropping the sensitivity on a flowing venue reduces the risk of false bleeps caused by line tension without losing genuine bite detection. For most stillwaters and moderately paced rivers the set covers the job comfortably.
On venues with a particularly strong push of water, a set with a fully adjustable dial may offer more precise control, but the SKS2 handles the majority of situations most carp and specimen anglers are likely to encounter.
Does the SKS2 have a silent mode?
. Silent mode sits at the bottom of the six volume settings on both the alarm heads and the receiver. On the alarm head, the LEDs continue to function in silent mode. On the receiver, you can also run vibro mode as a standalone option without any sound at all, which makes the SKS2 a more versatile choice for discreet fishing than sets without a vibrating receiver.
How does the night glow LED function work on the SKS2?
The night glow function is activated by pressing and holding the tone button on the alarm head. This brings up a low-brightness glow from the two front LEDs in whatever colour you have selected for that alarm, giving you a subtle visual fix on your rod positions in total darkness. Press and hold the same button again to switch it off.
What configurations is the SKS2 available in?
The SKS2 is available as a 2+1 set with two alarm heads and a receiver, and as a 3+1 set with three alarm heads, a receiver, and the wireless bivvy light. Individual alarm heads and receivers are also available separately, so you can expand an existing setup or replace a component without buying the full set again.
Can I use the SKS2 bivvy light independently of the alarms?
Yes. The bivvy light has a manual on and off mode that operates entirely independently of the alarm system. It can be switched on as a standard light whenever you need it, and it also has an automatic mode that triggers illumination the moment one of the paired alarm heads fires.
The two modes give you full flexibility depending on whether you want the light on constantly or only when a take comes.
