Prologic SNZ 4 Rod Bite Alarm Set with Receiver

Prologic SNZ Review: The Angler’s Verdict

With a solid 4.6-star rating from verified buyers, the Prologic SNZ stands out as a highly reliable and versatile 4+1 presentation set.

It combines a fully waterproof build with sophisticated features typically found on more expensive models, such as dedicated drop-back indication, a 150 m range, and intuitive operation via adjustment wheels.

Praised for its “plug and play” simplicity and excellent sensitivity, it performs exceptionally well for carp, pike, and barbel fishing alike.

Who is this bite alarm for? This system is the perfect choice for budget-conscious anglers who demand professional reliability and comprehensive features without the premium price tag.

It is equally suitable for newcomers to carp fishing wanting a complete set, as well as seasoned specimen hunters seeking a robust, no-nonsense system for all weather conditions.

Below, we have detailed exactly how we rated the Prologic SNZ wireless system. We have also summarised real angler reviews to give you a quick snapshot of the pros and cons of the Prologic SNZ Bite Alarm.

Our Verdict: The Prologic SNZ Bite Alarm

 

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

The Prologic SNZ is an absolutely waterproof, wireless bite alarm system featuring a roller wheel motion sensor and a reception range of 150 m. While it offers solid performance for its class, please note it does not feature accessory compatibility for external devices.

The Prologic SNZ Bite Alarm wireless system boasts a range of up to 150 m and operates using a classic roller wheel detection system.

Wireless alarms offer a distinct stealth advantage when targeting wary fish or angling in the margins: the volume on the alarm head itself can be silenced completely. This ensures the audible signal is only transmitted to your receiver, preventing the noise from spooking fish close to the bank.

In our comprehensive comparison, we reviewed alarms with ranges spanning from 100 m all the way up to 750 m.

While the Prologic SNZ’s 150 m range is on the lower end of this spectrum, it represents excellent value for the entry-level price segment and is more than adequate for most typical carp fishing scenarios.

Regarding detection, the Prologic SNZ relies on the proven roller wheel mechanism. While some alarms utilise infrared sensors for higher sensitivity, these can be prone to false indications during heavy rain or adverse weather.

Consequently, the roller wheel remains the industry standard, favoured for its reliability in all conditions – aided significantly by the unit being absolutely waterproof.

Accessory compatibility refers to the ability of the bite alarm to wirelessly pair with external devices, such as a bivvy light that automatically illuminates when you get a bite. Please be aware that the Prologic SNZ Bite Alarm does not feature this specific connectivity.

If you are specifically looking for a bite alarm featuring Accessory Compatibility, the Sonik SKS2 makes for a brilliant alternative. As a major bonus, the compatible wireless bivvy light is already included in the set.

 

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

The Prologic SNZ Bite Alarm is equipped with dedicated drop-back indication and a latching LED. Additionally, it boasts a night light function and a vibration mode on the receiver.

Dedicated carp and specimen anglers distinguish between two specific types of bites:

• The Run: The fish swims away from the angler, stripping line from the spool.
• The Drop-back: The fish swims towards the angler, causing the line to go slack.

On the Prologic SNZ Bite Alarm, drop-backs are clearly identified by the right LED flashing intermittently. In contrast, during a full-blown run, both LEDs will light up simultaneously. This 4+1 set makes identification effortless, featuring alarms with Red, Green, Blue, and Yellow LEDs.

A latching LED (memory LED) is crucial when fishing with multiple rods, allowing you to instantly identify which rod produced the single beep. With the Prologic SNZ’s latching LED, you never lose track of the action.

Furthermore, the integrated night light function offers a useful visual reference point during night sessions, with three different modes available to suit your preference.

Another highly practical feature is the vibration alarm on the Prologic SNZ wireless receiver. Both the alarm heads and the receiver can be completely muted, allowing bite indication solely through vibration on the receiver – perfect for maintaining absolute stealth.

 

Volume / Sensitivity / Tone / Anti-Theft Alarm

The Prologic SNZ features fully adjustable volume, tone, and sensitivity settings to suit any angling situation.

Sensitivity, volume, mute, and vibration modes can be adjusted using the adjustment wheel. The tone is adjusted using a button located on the right-hand side of the alarm.

However, please be aware that this model does not include an integrated anti-theft alarm.

The Prologic SNZ Bite Alarm system offers a comprehensive range of customisation options, allowing you to fine-tune volume, tone, and sensitivity to suit any angling situation.

Volume Settings: The alarms feature 10 distinct volume levels, ranging from whisper-quiet to extremely loud. To avoid spooking wary fish in the margins, it is often a smart move to mute the alarm head completely and rely solely on the receiver for indication.

Tone Settings: You also have 5 different tone settings at your disposal. While high-pitched tones cut through the wind and are easily audible, some anglers find them too piercing.

The tone control allows you to easily switch to a deeper, more subtle sound if preferred. The tone is adjusted using a button located on the right-hand side of the alarm.

Sensitivity Settings: Another crucial adjustment is the sensitivity. In adverse weather conditions with high winds or strong currents, standard settings can often lead to “false indications” (beeps when no fish has actually bitten).

These false alarms can be eliminated by dialling down the sensitivity via the adjustment wheel. The Prologic SNZ offers 5 different sensitivity levels to ensure your alarm only sounds for a genuine take.

Some high-end alarms offer a dedicated Anti-Theft feature. This function detects when a rod is physically lifted off the alarm by a person – rather than a fish taking line – triggering a continuous alert to warn the angler of potential tackle theft.

Please be aware that the Prologic SNZ Bite Alarm does not feature this specific security system. The most affordable bite alarm in our comparison featuring an anti-theft alarm is the Sonik Gizmo2, priced at around £250.

 

Batteries Required / Box Contents

The Prologic SNZ presentation set comes fully equipped with four alarms, a receiver, five protective covers, a padded carry case, and a lanyard. Regarding power, the system relies on standard 9V (PP3) batteries for both the alarms and the receiver.

The choice of using standard 9V (PP3) batteries for both the alarms and the receiver is a practical one. They are reliable and available at any petrol station or tackle shop, meaning you never have to worry about sourcing obscure battery sizes.

.The alarms also feature a low battery warning, indicating exactly when the battery is low so you aren’t caught out with a dead unit on the bank.

The box contents for this 4+1 set offer exceptional value for money. You receive 4 x Bite Alarms, 1 x Receiver, 5 x Protective Covers to keep your units safe, 1 x Lanyard with Carabiner, and 1 x Padded Carry Case for transport.
