Who it suits
Is it right for you?
Great for
- Overnight carp anglers. You get a receiver, proper night-time LEDs and a bivvy lamp that can come on with the alarm — dead handy when a screaming take arrives.
- Anglers building a multi-rod setup. The 3+1 and 4+1 versions cover common carp setups, while the receiver’s four channels can handle more alarms if your fishing grows.
Maybe skip if
- Minimalist day-ticket anglers. If you only need a simple single alarm, the receiver and lamp features may be more kit than you’ll use.
- Anyone who hates battery admin. The receiver and lamp are convenient, but every alarm head still needs three AAA batteries, and you’ll need to keep spares in the tackle bag.

Quick verdict
A tidy all-in-one alarm package
The Sonik Gizmo2 gives you the key bits for a modern carp session: clear multi-colour alarm heads, a feature-packed receiver and a bivvy lamp that can kick into life when a rod goes.
It’s not the most stripped-back alarm setup around, but the long wireless range, drop-back indication, vibration mode and rechargeable lamp make it a versatile package for overnight anglers. Just remember to buy AAA batteries for the alarm heads.

The multi-colour LEDs, frosted illuminated snag ears and integrated lamp point to a well-equipped package.
Up to 200 metres of range, multiple receiver controls and drop-back indication cover the main jobs well.
Clear alerts and drop-back information can help you react properly, while the lamp makes night-time fish care easier.
The controls and attachments are flexible, though the number of features means a little setup time.
Combining alarms, receiver and rechargeable bivvy lamp gives the package strong value for anglers who’ll use the extras.

The full rundown
Everything you'll want to know about the Sonik Gizmo2 Alarm Set + Bivvy Lamp
There’s a lot to like about an alarm set that understands the bit after the rods are off. The Sonik Gizmo2 Alarm Set + Bivvy Lamp isn’t just a couple of bleeps and a receiver. It brings the alarm heads, wireless receiver and a synchronised bivvy lamp together in one tidy package. For an overnight carp angler, that can make the whole night feel a bit more joined-up.
You can choose the set to match your rods, with 2+1, 3+1 and 4+1 versions available. The relevant model numbers are HC0087, HC0088 and HC0089 respectively. So whether you’re fishing a compact two-rod swim or running four rods on a bigger water, there’s a sensible starting point rather than buying spare heads you don’t need.
The alarm heads use twin high-visibility multi-colour LEDs, which gives you clear visual feedback when you’re watching several rods in low light. They also have illuminated snag ears with a frosted finish. That’s a useful touch when you’re checking the setup after dark, especially when a rod is fishing tight to the margins or you’re trying to see exactly which alarm has lit up.
For the receiver, the headline figure is a range of up to 200 metres. Your real-world range will always depend on the lake, bankside cover and where you’ve put the bivvy, but there’s plenty of reach here for normal carp fishing. The four-channel receiver can sync with up to eight alarms, giving the system room to grow if you add rods or want to link another compatible alarm into the setup.
The receiver is properly loaded, too. There are six volume levels plus silent mode, so you can keep things discreet when the lake is quiet or turn it up when you’re tucked into the sleeping bag. Drop-back LED indication helps separate a run from a liner heading the wrong way, while the torch function and vibro mode are both genuinely useful when you’re trying not to light up the whole swim.
The clever extra is the bivvy lamp. It has a built-in 2000mAh rechargeable lithium-ion battery and charges through USB-C, which keeps charging straightforward with the cable setup most anglers already carry. It can illuminate manually or respond to an alarm trigger, so you’ve got a choice between using it as general bivvy lighting and letting it help during those frantic midnight take-offs.
There’s decent control over that light as well. Six brightness levels let you keep it subtle while tying a rig or brighten things up when you’re sorting a net and unhooking mat. Six delay modes help tailor how long it stays on after the alarm event. The magnetic and hook attachments should cover most bivvy arrangements without turning placement into a right old faff.
The main thing to plan for is power. Each alarm head uses three AAA batteries, and they aren’t included. That’s not a deal-breaker, but it’s the sort of small job that can leave you gutted if you only discover it while packing the car. The lamp itself is rechargeable, though, so give it a top-up before a session and keep spare AAAs in the tackle bag.
Overall, the Gizmo2 looks best suited to anglers who want more than a basic alarm pair. The lights, drop-back indication, vibro mode and lamp integration all have a place on the bank. It’s a feature-rich setup rather than a bare-bones one, but for overnight carp fishing that extra flexibility can be properly handy when the rods are on the munch.

Our take
The clever bit is the lamp
Plenty of alarm sets stop at the receiver. The Gizmo2 carries on with a synchronised bivvy lamp, giving you a bit more light and information when a take rips off in the dark.
That makes it especially appealing if you like your kit working together rather than juggling separate gadgets on the bivvy table.
The package
A full night-time setup rather than just a set of bleeps
The Gizmo2 package gives you alarm heads, a receiver and a synchronised bivvy lamp. Choose between 2+1, 3+1 and 4+1 sets to suit the number of rods you normally fish. Twin multi-colour LEDs make the heads easy to identify, while illuminated frosted snag ears add extra visibility around the bobbin and line.
The receiver brings six volume levels, silent mode, drop-back LED indication, a torch function and vibro mode. That’s a useful spread for both day sessions and proper overnight fishing. You can keep the sound low and rely on the visual or vibration alerts when you’re trying to stay discreet.
Worth knowing. The alarm heads need three AAA batteries each, and they’re not supplied. The bivvy lamp is rechargeable through USB-C, but it’s still worth packing fresh AAA spares before a session.
On the bank
Made for anglers who like their kit talking to each other
The 2+1 version makes sense for a pair of rods, while the 3+1 and 4+1 options suit more typical carp setups. With four receiver channels and the ability to sync with up to eight alarms, there’s also some breathing room if your setup changes later.
The bivvy lamp is the biggest reason to choose this package over a simpler alarm set. Put it on a magnetic or hook attachment, set your preferred brightness and delay, and it can illuminate manually or when an alarm triggers. That’s bob on when you’re fumbling for boots and a headtorch during a night-time run.
Worth knowing. A range of up to 200 metres is generous for normal bank fishing, but don’t treat it as a guarantee across every swim. Trees, banks and buildings can all affect wireless performance.
Quick answers
The stuff you’ll want sorted before the first session
The receiver has four channels and can sync with up to eight alarms, although the retail sets are supplied with two, three or four alarm heads. That gives you flexibility without forcing every angler into the biggest package.
The bivvy lamp has six brightness levels and six delay modes. Use a low setting for a subtle glow in the bivvy, or increase it when you’re dealing with a net, mat and a lively lump outside.
Worth knowing. Keep the lamp charged before heading out, and check every alarm head has fresh AAA batteries. It’s a tiny bit of prep that avoids a very naff start to a bite-time session.
