Below, dive into our comprehensive review of the Sonik Gizmo2. We’ve also collated real-world customer feedback to give you a snapshot of the key pros and cons of this best-value alarm set.

Our Verdict: The Sonik Gizmo2 Bite Alarm

 

Bite Alarm Type / Range / Type of Motion Sensor / Accessory Compatibility

The Sonik Gizmo2 is a highly versatile wireless alarm system that operates with a solid 200m operating range.

It utilises a reliable Roller Wheel mechanism for detecting line movement and sets a new standard in this price bracket by offering exceptional accessory compatibility right out of the box.

While some premium alarms like the Nash Siren R4 and the Delkim Txi-D boast ranges of over 500 m, the Gizmo2’s 200 m range is more than sufficient for 99% of UK angling scenarios, ensuring a strong connection between your rod pod and the bivvy.

A massive advantage of this system is the direct integration with the included Bivvy Light. Unlike many competitors where the lamp is an expensive add-on, the Gizmo2 connects seamlessly to the provided light, which offers automatic illumination when an alarm is triggered.

For core detection, the unit relies on the Roller Wheel. The design is compact and sleek, featuring a sealed case with rod-friendly rubber inlays to ensure your valuable carbon blanks don’t slip or get scratched during a violent take.

Regarding connectivity, the alarms also feature a 2.5 mm Power Out Socket, allowing for the use of illuminated hangers or swingers for those who prefer additional visual indication at night.

 

Special Indication for Drop-Back Bites / Latching LED / Receiver with Vibrate Mode / Night Light

The Sonik Gizmo2 delivers excellent visual feedback, featuring Twin Hi-Visibility Multi-Colour LEDs and Special Drop-Back Indication, a 20-Second Latching LED, a Receiver Vibrate Mode, and a dedicated Night Light function.

Visually, the alarms are stunning. The Illuminated Snag Ears feature a frosted finish, diffusing the light perfectly. You can choose from multiple colours thanks to the Multi-Colour LEDs, allowing you to colour-coordinate your setup (Red, Blue, Green, etc.) which automatically syncs to the receiver.

The system offers a clever Special Drop-Back Indication. When a fish swims towards you (slack line), only the Snag Ears glow slightly dimmer and flash afterwards. This distinct visual pattern allows you to instantly distinguish a ‘drop-back’ from a screaming run.

The unit includes a Latching LED which remains illuminated for 20 seconds after the activity has stopped. This is vital for locating the active rod quickly when waking up to a bite in the middle of the night.

For stealthy anglers, the receiver features a Vibro Mode, allowing you to keep the volume silent while still being alerted physically. Additionally, the receiver doubles as a torch, and the included Bivvy Light offers a ‘Delay Adjustment’ (six modes), keeping your shelter lit for a set time after the bite occurs.

Finally, the Gizmo2 incorporates a Night Glow LED function, providing a subtle, low-level presence light to help you navigate your swim in total darkness.

 

Volume / Sensitivity / Tone / Anti-Theft Alarm

The Sonik Gizmo2 provides incredible adjustability across its alerts and features a smart, reactive Anti-Theft Alarm.

Control is at the heart of the Gizmo2 design. The unit offers 8 levels of volume, including a completely silent mode. This is perfect for the discrete angler who only wants the receiver to sound inside the bivvy, keeping the bank quiet.

Similarly, you have access to 8 levels of tone and 8 levels of sensitivity. This wide range of sensitivity settings is crucial for UK waters; you can dial it down for fast-flowing rivers or strong winds to prevent false bleeps, or crank it up to detect the most finicky bites in winter.

A standout feature for ease of use is the Intelligent Mute Mode. This allows you to silence the alarm temporarily with a button press – ideal for setting your bobbins or tightening your line without annoying the whole lake.

Crucially, the Gizmo2 includes an Anti-Theft Alarm. The receiver sounds an alarm immediately if a head unit is powered down whilst the receiver is still switched on.

Only two other, much pricier models in our line-up – the Nash Siren R4 and Delkim Txi-D – share this Anti-Theft capability. This gives the Sonik Gizmo2 a real edge, offering a level of security that is certainly not standard in this price bracket.

Since the alarms are switched off by replacing the hard case cover, this feature ensures that if anyone tries to covertly ‘silence’ your alarm to steal it, you will be alerted instantly.

Furthermore, the receiver boasts Auto Alarm Head Tone Matching, meaning whatever weird and wonderful tone you select on the bankstick is automatically replicated on your receiver.

 

Batteries Required / Box Contents

The alarms and receiver operate on standard 3 x AAA batteries, while the included Bivvy Light features a built-in 2000mAh rechargeable battery. The complete set includes 3 x Bite Alarms, 1 x Receiver, and 1 x Bivvy Light, along with 6 removable illuminated snag ears and a protective case.

The choice of 3 x AAA batteries for both the alarms and the receiver is a practical one for the UK market. They are cheap, reliable, and available at any petrol station or tackle shop, meaning you never have to worry about obscure battery sizes.

The alarms also feature a Silent Low Battery Warning, so you aren’t caught out with a dead unit.

The Bivvy Light is a highlight of the package, featuring a robust built-in 2000mAh rechargeable lithium-ion battery and a Superfast USB-C charging port, making it easy to top up from a power bank on the bankside.

The box contents for this presentation set are exceptional value for money. You get 3 x Bite Alarms, 1 x Receiver, and 1 x Bivvy Light. Additionally, the set comes complete with 6 illuminated Snag Ears (integrated but removable) and a protective case.

The receiver is designed with a table-top free-standing case and a lanyard attachment point for portability.

 

What Owners Are Saying: A Customer Review Round-up

At the time of writing, we found 15 customer ratings for the Sonik Gizmo2 and Gizmo1 bite alarm across Amazon and Angling Direct. On average, buyers have rated the Sonik Gizmo an impressive 4.7 out of 5 stars.

• I love them and they work well.
• Love Sonik kit. Had the Gizmo 1s – never failed me. Just felt like an upgrade, so got these. The alarms turning on/off when the face cover is on is a nice addition. Personally, I think the Gizmo 1 bivvy light is better, and the Gizmo 1s took fewer batteries. But the Gizmo 2s are colour-coded (all different colours), whereas the Gizmo 1s were all blue. Great bit of kit. Why spend £500 on Delkims?
• Just what I was looking for! Great upgrade from my existing set. Packaged well. Would buy from this seller again.
• These alarms are the second 3+1 set of Soniks I have bought. I love these alarms, and the bivvy light is a bonus too. I still use my first set without worrying about them, but I now have a backup if I need it.
• This was a great purchase and an unbelievably good price. A really great buy.
• Great place to shop and a good value.
• Great quality and fantastic price.
• Bought as a present for someone. Not used yet, but they look awesome.
• Great alarms and receiver set. Easy to use and set up. Great value for money.
• Delightful.
• Great quality item, best price around.
• Nice setup, easy to set up. Great set of alarms.
• Great alarm set! Small, compact, tidy, and just overall a great alarm set! The bivvy light is a great addition that also makes life easier when night fishing!

The feedback from the angling community regarding the Sonik Gizmo2 is overwhelmingly positive. Owners consistently highlight the exceptional value for money, often noting that the system offers premium performance without the high price tag associated with other leading market brands.

Many anglers have upgraded from previous versions of the Gizmo range to this newer model.

They particularly appreciate modern improvements such as the multi-coloured LEDs – moving away from the single-colour setup of the predecessor – and the smart design where the alarm powers down automatically when the protective face cover is attached.

The system is frequently described as compact, tidy, and incredibly easy to set up right out of the box. A particular highlight for many users is the included bivvy light, which is seen as a practical addition that significantly improves the night fishing experience.

Whether purchased as a primary setup, a reliable backup, or even as a gift, the general consensus is that the build quality, combined with the comprehensive feature set, makes this alarm system a highly recommended choice for carp anglers.

In our view, the Sonik Gizmo2 features 8 settings for volume, tone, and sensitivity, plus an anti-theft alarm – specs typically reserved for premium alarms with a much heftier price tag.

Other standout features include the highly visible drop-back indication and multi-colour LEDs. Coming in at well under £300, it packs a serious amount of tech for the price, making it our undisputed Best Value for Money winner.
