Key Takeaways

  • A medical alert system with GPS is a good investment if you need emergency coverage when you’re away from home.
  • Not all medical alert systems have GPS capabilities. On-the-go devices are the most common medical alert systems with GPS.
  • Medical alert systems with GPS allow monitoring center operators and loved ones to identify the location of a person wearing the device.
  • Monitored medical alert systems with GPS use cellular service to connect with a call center.
  • You can wear the mobile GPS help button that comes with a medical alert device on your wrist, around your neck, on a belt buckle, or carried in a bag or purse.

What Is a Medical Alert System with GPS?

The National Institute on Aging recommends medical alert systems—also known as personal emergency response systems—for older adults who live alone, as they are at a higher risk for falls and fall-related injuries compared to younger adults. 

Medical alert systems with GPS are mobile devices that connect to a monitoring center via cellular network or Wi-Fi. Devices with GPS tracking allow caregivers to always see your location and know if you’re safe. Your exact location is also shared with the monitoring center agent during an emergency.

Active older adults who live alone frequently invest in mobile medical alert devices with GPS technology because they provide easy access to help during an emergency, even if the wearer doesn’t know their exact location. 

“Medical alert systems often restore older adults’ independence, which can have a positive effect on their health and wellbeing as well,” says Jenny Sanford, an Adult-Gerontology Primary Care Nurse Practitioner and Caregiving Coach in New York. 

You can wear a medical alert device with GPS around your neck, on your wrist, on a belt buckle, or you can carry it in a bag or purse. During a medical emergency, you press the help button on the device. This initiates two-way communication with an operator at the company’s monitoring center, who will respond to your emergency by contacting friends, family, or 911, if necessary. Since it uses GPS and cellular technology, operators and responders can pinpoint your exact location even if you can’t relay that information.

How Do Medical Alert Systems with GPS work?

Medical alert systems with GPS come with a help button that connects to a monitoring center during a medical emergency. When activated, the help button initiates two-way communication with an operator at the monitoring center who will respond to your emergency by contacting friends, family, or 911, if necessary. Since it uses GPS and cellular technology, operators and responders can pinpoint your exact location.

Types of GPS Medical Alert Devices:

In general, GPS medical alert devices come in four styles: bracelet, pendant, cellphone, or smartwatch.

Bracelet or wrist button: GPS wrist buttons or bracelets look like a watch but only contain the help button that alerts the monitoring center or designated emergency contact. They typically come in black or white and are easy to adjust and operate.

Pendant or necklace—A wearable GPS neck pendant is attached to a lanyard and resembles a large necklace. It generally sits at mid-chest level. Most devices are a bit bulky, so this is not ideal for people looking for something discreet. However, if you like the pendant help button but don’t want to wear it around your neck, ask about clipping it to a belt buckle or carrying it in a purse or bag.

Cellphone—All monitored medical alert systems come with a wearable help button or smartwatch. That said, some companies offer a separate app or subscription-based service you can use on a cellphone that works like a medical alert system by alerting emergency services when activated. This might be a good option for the average adult who wants quick access to emergency help, but it is not ideal for older adults who need closer monitoring or don’t want to carry a phone at all times.

Smartwatch—GPS medical alert smartwatches are newer devices offered by select medical alert companies. They often come with a one-time fee, but you can keep and use the watch even after canceling the monthly monitoring service. Most GPS medical alert smartwatches look like a typical wristwatch. Unlike the average smartwatch, they have a help button on the face or side of the watch that you can activate during an emergency. Some models also come with other features like step tracking, heart-rate monitoring, text messaging, and two-way communication.

What Is the Difference Between GPS Medical Alert Systems and Mobile Systems?

Medical alert systems with GPS are considered mobile systems that work via cellular technology. GPS capabilities allow an operator at the monitoring center or an identified emergency contact to identify your exact location even if you can’t respond.  

Most mobile medical alert systems use GPS, but standard mobile systems without tracking technology can’t share your location with loved ones or a monitoring center agent. This can be dangerous if you’re unresponsive or unsure where you are. 

Do I Need a Medical Alert System with GPS?

Deciding if you need a medical alert system with GPS comes down to a few factors. First, you may not need a GPS-enabled device if you are housebound and have a medical alert system with a base unit. According to Denise Brown, a consultant for medical alert device company and professional caregiving coach, a medical alert system equipped with GPS capabilities is beneficial for users because of the freedom and independence that it provides. “Some aging seniors may still have their mobility and mental agility but elect to start using a medical alert device because they find themselves living alone after losing a spouse, or just as a precaution as they age,” Brown said. “A device with GPS allows you to move freely while also providing caregivers the peace of mind of being able to locate you when they’re not around.”

Medical alert systems with GPS may include fall detection technology, which is important when considering senior safety. This means you can go for walks, to the store, or on a drive knowing that a caregiver or call center can find your location should an accident or medical emergency occur. If you are still active, move around outdoors, and often leave your home, a medical alert with GPS is a good investment.

Where Can You Buy Medical Alert Systems with GPS?

You can buy medical alert systems with GPS online or over the phone. The majority of companies have websites with details about devices, plans, fees, warranties, return policies, and information on how to order. Most sites have ordering systems that allow you to complete the entire process online. With that said, some sites have limited information and require a phone call to a customer service representative for prices, plans, and ordering. If you’re not comfortable purchasing a device and plan online, all medical alert companies listed in this roundup have excellent customer service and sales departments. They will answer any questions and assist you with selecting and purchasing a medical alert device. If you need help narrowing your search, take some time to read through the best medical alert systems reviews online.

Are Medical Alert Systems with GPS Waterproof?

Medical alert systems with GPS are either water-resistant or waterproof. Most are resistant to water, which means they can withstand splashing and high levels of humidity and are generally safe to wear in the shower or while bathing. If a device says it is waterproof, then most likely, it can handle being submerged for a short period of time. In general, avoid swimming or submerging any device for long periods of time in the water. Be sure to check the instructions that come with the device to determine its ability to handle water. Here are the specifications for the medical alert devices listed in this article:

  • Bay Alarm Medical: Water-resistant
  • Medical Guardian: Water-resistant 
  • MobileHelp: Neck pendant, wrist button, and fall button are all waterproof, but not designed to be submerged for long periods of time. 
  • Philips Lifeline: Waterproof in up to 1 meter of water for 30 minutes. 
  • LifeStation: Water-resistant  
  • LifeFone: Water-resistant 
  • Lively Mobile Plus: Waterproof

What to Look for When Shopping for a Medical Alert System with GPS

If you’ve decided to move forward with a medical alert device, the next step is to research various brands, styles, and systems. Here are some features to consider when shopping for a medical alert system with GPS.

Fall Detection

With automatic fall detection, you can wear a neck pendant or wrist button that automatically detects a fall based on your motion. If you fall, it contacts the emergency response center for you even if you can’t press the button. This feature is useful for all seniors, but it’s vital for older adults who have a history of falling or are at a higher risk of falling due to a medical condition or recent surgery. More than one out of four older adults fall each year, according to the Centers for Disease Control and Prevention (CDC).

With that in mind, it’s easy to see how falls are a good example of the value of monitored systems. “Falls are the number-one reason [the] independent elderly lose their independence and often lead to mortality…rapid response is key to protecting seniors,”  said Dr. James Dan, MD, a geriatric clinical advisor and member of the Senior Helpers board of directors. Automatic fall detection detects falls with integrated sensors that directly connect to the call center, allowing emergency responders to immediately bring help. Additionally, the call center can contact family or friends.

Response Time

The average response time for most call centers is up to 60 seconds. When shopping for a medical alert system with GPS, make sure to ask about the average response time, which includes the amount of time it takes for the monitoring center to respond once you activate the help button. It’s also a good idea to read reviews online that discuss response time.

Voice Activation

Voice activation is an extremely helpful feature when it comes to GPS medical alert systems. Having a medical alert that has two-way voice capability and connects to a live, dedicated agent can quicken response times and help you remain calm during an emergency. Having a kind, reassuring person to talk to is invaluable in these critical moments.

Battery Life

Battery life is a key feature when choosing a device. The battery life of mobile medical alert systems with GPS are often shorter than home-based systems. It’s not uncommon to have to charge the device every three to five days, with some even needing daily charging. If needing to charge a device daily is a problem, you should opt for a system that lasts at least two to three days on one charge.

Style

Medical alert devices come in a variety of styles, including neck pendants, wrist buttons, smartwatches, and even devices you can hold in your hand, clip to a belt buckle, or toss in a bag. Many medical alert systems come with a neck and wrist help button, giving you the flexibility to choose the style that’s right for you, while others, like a smartwatch, are only available in a wrist style. You should be able to check the specifications for each device on the website. These include dimensions and weight.

Warranty

Before deciding on a medical alert system, ask about warranties and read the fine print. Some companies offer a limited warranty that only covers short-term wear-and-tear, while others guarantee the product for life. Additionally, companies like Bay Alarm Medical offer a protection plan that covers replacement of lost or damaged items for an added fee.
