We’re just charging up the Ice Dot thing and having a go. You do need to activate it by finding the Dot before each ride and launching the app too. So far it can tell the difference between ‘jumping up and down’ and ‘helmet dropped onto the ground’. It does need a jolt to trigger it, but then anything sudden enough to knock you out will trigger it. And if you’ve ‘merely’ broken your leg, you can always just smack your head on the ground anyway. 🙂
It can send whatever text you want though, so it’s probably best to use set up with a friend/partner. They should know where you’re going and they’re the one to get the alert. You need to make sure you agree what the next move is then – Mountain Rescue, or whatever. They also need to have their phone one and with them…
It does need a phone signal though (and the instructions imply a data connection too, but I’m trying to work out if and why that’s the case…)
Review in a bit when we’ve had a good play with it.
