If he was eight nautical miles offshore then he was well within the range of terrestrial AIS, he could simply have sent a distress signal if he was in serious trouble.
You can buy outdoor cables that are UV shielded or even ones that are "armoured" that you can directly bury. I'd use conduit where possible though.
Random example from Scoop:
Scoop 100m Box Cat5e Outdoor FTP CCA Cable
Stay away from CCA like the cable above though.
You can’t really compare those results when the tests used very different criteria.
The Mazda 2 was tested in 2021, when Global NCAP was still based on the much older Latin NCAP 2013 protocol. Scoring four stars under that standard probably isn’t particularly impressive.
A three star Euro NCAP rating isn't bad, but it hasn't been tested by Euro NCAP. The Japanese version is sold in countries with higher safety standards.
The closest test result is probably the Dzire sedan that scored 5 stars in Global NCAP, but it probably wouldn't achieve more than 2 stars...
I don't think it works via the Asap app anymore (it did when they first became an eBucks partner), but it does work in store. I normally do it at PnP Clothing without purchasing anything else.
