Best Waterproof Medical Alert Systems

Bay Alarm Medical’s Waterproof Equipment

We bought a Bay Alarm Medical SOS Smartwatch so that we could test Bay Alarm’s most water resistant device.

While all of Bay Alarm Medical’s wearable devices offer some amount of water resistance, they’re not all equal. They all worked after we showered while wearing them, but some we needed to take off before hopping in the pool.

More specifically, the SOS All-In-One and the GPS Help Button only received an IPX6 rating whereas the SOS Micro and SOS Smartwatch received an IP67 rating. The second number in those ratings refer to the water resistance of the device with the six meaning it can withstand being sprayed with water, but cannot be submerged, whereas the seven means the device can be submerged in three feet of water for up to 30 minutes.

Bay Alarm Medical’s Pricing

For offering some of the best equipment in the industry, Bay Alarm does it at surprisingly low prices. They’re one of the most affordable options, especially for couples since they offer monitoring for two devices at the same price as monitoring for one. Here’s an overview of Bay Alarm Medical’s pricing:

Bay Alarm Medical’s Usability

The pendant that came with our Bay Alarm SOS Home system is water resistant so we could take it with us in the shower.

Where Bay Alarm’s usability really stands out is with their mobile app. Caregivers can see the location of their loved one clearly displayed on a map with a pin showing their location. That’s typical of a caregiver app, although when we tested MobileHelp, we found out that some providers limit the amount of times you can check up on your loved one’s location. Bay Alarm let us check as often as we wanted.

That’s not all, though. Bay Alarm’s mobile app lets caregivers manage every aspect of the user’s account. It let us check our purchase history, change emergency contacts, and add home entrance details for first responders. This makes it so your loved one doesn’t need to worry themselves with all the technical details of their medical alert system.

The rest of the system takes a similar approach where the responsibility of the user is minimal enabling them to receive as much help as they need to manage the system.

Medical Guardian’s Waterproof Equipment

Unlike with Bay Alarm Medical, every wearable Medical Guardian device is IP67 rated. That means you can take them in the shower or swim with them. As a reminder, we could only swim with some of Bay Alarm Medical’s alert devices since they were only rated IPX6.

Medical Guardian’s MGMove charged us extra if we wanted to access the Messages & Reminders feature.

Medical Guardian’s Pricing

Regardless of which system you want, expect to pay for the equipment upfront or finance it with Medical Guardian. No free equipment here. If you’re looking for free equipment, Bay Alarm Medical offers their at-home system with no upfront fees and ADT offers all of their systems with a flat $99 activation fee but no cost for equipment.

We understand why Medical Guardian charges for their equipment, though, because it’s some of the best in the industry. They made our list of the best medical alert smartwatches and the best medical alert necklaces. Here’s how much Medical Guardian charges for their equipment and services:

Medical Guardian’s Usability

Medical Guardian’s app is functional, but we think it could use a redesign to make it more user friendly.

Don’t expect a Bay Alarm quality mobile app from Medical Guardian. It’s still functional, but not nearly as easy to navigate and you cannot easily outsource all of your account management to a caregiver. Caregivers can still check the location of devices they manage, though. Check out our Bay Alarm vs Medical Guardian guide for an in-depth comparison.

What made Medical Guardian easy for us to use was its impressive range. That 1,400-foot range meant we didn’t need to worry about our device disconnecting when we swam in our backyard pool. It also allowed us to install our base station anywhere we wanted in our house since the range was not a limiting factor. Range limitations on other systems meant needing to install our base station in the middle of our house.

ADT Medical’s Waterproof Equipment

We already mentioned that ADT Medical’s wall-mount alert button is IP67 rated, which means it can be submerged in water; not that you’d need to. We recommend putting one up in the shower or near the tub for easy access. Don’t go putting it in the tub, though.

All other ADT alert buttons are IP67 rated as well. This means users do not need to think about whether or not they’re wearing the right alert button for any activity. With all buttons rated at IP67, you can take any of them with you everywhere you go.

ADT Medical’s Pricing

ADT Medical’s pricing structure includes a $99 activation fee across all systems. While they advertise “free equipment,” this activation fee effectively serves as a fee for the equipment. That said, $99 remains competitive compared to other providers — Medical Guardian’s systems, for example, start at $150 for equipment. Plus, ADT regularly discounts this activation fee down to $59.

Either way, $99 is an affordable price for a medical alert system considering Medical Guardian’s systems start at $150. Here’s a complete breakdown of ADT Medical’s prices:

ADT Medical’s Usability

ADT Medical takes a streamlined approach to usability. Unlike Bay Alarm and Medical Guardian, there’s no mobile app to navigate — just straightforward, plug-and-play equipment. Setup is simple: plug in and charge your equipment, call ADT to activate your system, and you’re ready to go. From there, just press the help button on your pendant or the wall-mount button when you need assistance.

This approach surprised us, because when we tested ADT’s home security system, we had the exact opposite experience. It was filled with technology and they make one of our favorite home security system apps. We think this is something they should add to their medical alert system, even if just for caregivers.

Lifeline’s Waterproof Equipment

All Lifeline devices with a help button — except the base station — can be submerged in water for up to 30 minutes. We appreciate this consistency across their product line, as it makes it simple to understand your device’s waterproofing without having to check each model individually.

Lifeline’s Pricing

If you’ve browsed Lifeline’s website, you might think they only offer three systems. However, the Home and Mobile Systems each have two different configurations, bringing the total to five distinct systems. That can make price comparisons tricky, so we created a Lifeline pricing table comparing all your options:

Lifeline’s Usability

We were able to have our Lifeline system fully set up and functional within 10 minutes of it arriving at our house.

Setting up a Lifeline alert system is remarkably straightforward. It took us just four steps — one of which was simply unpacking the equipment from the shipping box. Our entire setup process took approximately 10 minutes from start to finish.

After that, we also set up the Lifeline mobile app which provided nearly as much functionality as the Bay Alarm mobile app for caregivers. However, we still preferred the Bay Alarm mobile app. Our Lifeline app was slow to refresh and missed notifications from time to time. Aside from the mobile app, though, using our Lifeline system to request assistance was simple.
