A man from Washington states is thanking his dad’s Apple Watch’s “Hard Fall Detection” feature after it alerted him that his father got into an accident.

On a Facebook post that was made by Gabe Burdett, it said that he was going to meet Bob, his father, in the Riverside State Park for mountain biking.

But the father didn’t arrive at their meet-up location in the State Park.

While waiting at the meet-up, Burdett received a text message from his dad’s Apple Watch.

The message said, “Emergency SOS Bob Burdett called emergency services from this approximate location after Apple Watch detected a hard fall.”

The Apple watch alerted Burdett that it had called 911 with his father’s location, as he later found out that his dad flipped his bike and hit his head.

The incident knocked him out unconscious.

During an interview with KREM, Gabe Burdett said, “He didn’t remember flipping his bike and he didn’t remember anything really happening until he was in the ambulance, and even then he was pretty out of it.”

An emergency ambulance arrived at the scene and his father was transported to the hospital within thirty-minutes of the fall.

Gabe said, “It’s been an amazing tool. … You think of fall protection as something like falling off a ladder, but not for doing something you do all the time.”

Bob, the father, had a number of X-rays and a CT scan after his fall.

Gabe said his dad is doing great and is recovering.

In the Facebook post that Gabe made, he asked people who own the Apple Watch to turn on the capabilities and features of the watch.

In his Facebook post, he said, “IF YOU OWN AN APPLE WATCH, set up your HARD FALL detection—it’s not just for when you fall off a roof or a ladder.”

He added, “Had he fallen somewhere on the High Drive trails or another remote area, the location would have clued EMS in on where to find him. Amazing technology and so glad he had it!”

Amazing tech by Apple!
