Cell boosters can only do so much… it a good tool to address weak or intermittent signal issues, not a solution for venturing off the beaten path. Personally I would not consider this a reliable means to get off-road coms.

If you are worried about communications from a safety and preservation of life standpoint… then really the best option solution is something like the Garmin Inreach which works off the Iridium satellite constellation. Consider it the modern day 2-way pager for those who cant really afford a satellite phone. The device can also be used a satellite modem allowing you to text message from your phone.

Personally I love radio coms. Ham radio is a good intermediate option… but you need a license to do it right. It cost next to nothing to get licensed, but you can hop onto repeaters and get coverage for hundreds of miles. I can easily talk to someone 100-200 miles away using a simple handheld radio.

Rugged Radios is ok. They market hard to the off-road community, but there equipment is nothing more than pre-programmed Chinese Baofeng radios with an insane markup. What ever they sell you for $75, you can buy yourself for $25.

That said, unless you are at a race event, its near useless too. If you want real radio coms, you need to get on repeaters, and to do that, you need a license.

That said… I much rather buy stuff from brands like Yaesu, Kenwood, and ICOM. Enough thought I own like 6 of those as well… it’s just disposable to me.
