Where the ZOLL AED 3 Excels

The ZOLL AED 3 is often the best choice when:

CPR Quality Is the Priority

Many rescuers are hesitant during an emergency and may not push hard enough or fast enough during CPR.

The ZOLL AED 3 provides real-time feedback showing whether compressions are deep enough and fast enough. This feature can significantly improve CPR performance and confidence.

You Have Untrained or Infrequent Responders

The full-colour screen and visual instructions make the rescue process easier to follow, even for someone who has never used an AED before.

Tough Environments

The IP55 rating provides excellent protection from dust and moisture, making it a strong choice for:

Construction sites
Manufacturing facilities
Warehouses
Outdoor recreation facilities
Industrial settings

Where the LIFEPAK CR2 Excels

The LIFEPAK CR2 is often the best choice when:

You Want Maximum CPR Time

Its cprINSIGHT technology can analyze heart rhythm while CPR continues, reducing interruptions and maximizing chest compressions.

You Need Bilingual Operation

The bilingual English/French LIFEPAK CR2 is one of the most popular AEDs for:

Government facilities
Municipal buildings
Schools
Public-facing organizations
National employers

You Manage Multiple Locations

The LIFEPAK CR2's remote monitoring capabilities allow organizations to monitor device readiness, battery status, and pad expiration dates remotely through connected management tools.

This makes it an excellent choice for:

Multi-site employers
School boards
Property management companies
National organizations
