Poolguard GAPT-2 Outdoor Pool Gate Alarm

⭐ Best Alarm for Pool Gates

If you’re looking for a pool alarm to secure your gate, it’s hard to do better than this one. It has some great features that make it ideal for multiple uses, including detecting when kids and pets enter the pool area or when you want to get an intruder alert.

For starters, the GAPT-2 has an 85-decibel alarm, which is very loud. The range is only 10 feet, so you can’t install a receiver in the house, but 85 dB is loud enough to reach every corner of a large property.

It not only works when someone opens the pool gate but also sounds when it is left open. You can get an alert if the pool area is not secure.

It also links with multiple alarms, so it is possible to rig all corners of your swimming pool. Of course, the big problem is that it’s easy to get false alarms since it gets set off by movements on the surface of the pool. To prevent this, you can set it to an appropriate sensitivity level.

It has more sensors and features than most other models, and it can detect anything entering your pool, including your child or your pet.

You also don’t have to worry about false alarms since it can only detect things that weigh more than 18 lbs. This sensitivity might not help your lighter pets, but it ensures your toddlers are protected.

You only have to remove a section of railing, install the alarm, and then replace it. The PoolEye is best for use with pools that are 24 feet in length or smaller.

This pool alarm is pretty loud, and it does its job well, but it has the downside of not having a remote receiver, so the alarm will only sound poolside.

Recap: The Best Pool Alarms

My Research Criteria

First, I need to consider the types of pool alarms. The type of pool alarm you get depends on what you want to prevent from entering the pool. There are at least three types of pool alarms (you can read more about them below or in my, What Is a Pool Alarm? article).

Pool Entry Alarms

These pool alarms sound when anything enters the pool. They include surface sensor alarms, which float on your pool, and sub-surface sensor alarms, which get mounted on the wall underwater.

User Entry Alarms

User entry alarms are worn on the wrist and are mostly for children.

Once a child wears it, the alarm is locked and will sound when the child gets the band wet. These devices will let you know when the child enters any water (not just the pool).

Gate Alarms

Gate alarms, as you might have guessed from the name, are attached to the pool gate and often employ a magnetic sensor to sense when someone opens the gate.

Outside of the type of alarm, here are the other factors that went into my research.

The Volume

When buying a pool alarm, you should get one that you can hear from as far away as possible. That means it needs to be loud enough to hear the alarm even if the pool is far from the house.

That said, it shouldn’t be so loud that it ends up being more of a nuisance. You should also consider the local by-laws, as you don’t want a pool alarm that is so loud that it causes a disturbance to the neighbors and earns you a fine.

Easy to Use

The alarm should be easy to use. It should be simple to turn on and off, especially if you’re getting it for children. It might get set off several times a week, and you don’t want something tedious to turn off if there is a false alarm.

The Type of Setup

Setup is an essential factor when buying a pool alarm. Different pool alarms work best in specific settings.

Some are best for use in inground pools while others are best for use in above-ground pools. Some will float on the water while others are for wearing on wrists.

Yet others are mounted on the gate. All of these have advantages and disadvantages. Choose the one that best meets your needs.

The Range

The range is a vital thing to consider for pool alarms that come with a receiver. The receiver will only work within a specific distance.

Therefore, you should buy a pool alarm with the right range for your needs depending on the distance between your house and the pool.

Value and Recalls

The quality of the pool alarm also matters. You want value for your money, and so you should go for models from reputable brands that deliver quality. These are not necessarily the most expensive options. I also looked at brands that have been recalled before and avoided those products.
