As AD mentioned, it's a dual band and will cover the most common HAM frequencies. I'll echo his concerns about range. An HT is something you use to Tx point-to-point, or point-to-repeater, over a range of just a few miles. Less in urban or very hilly areas.
I've had passing experience with Baofeng products and wasn't impressed. It's better than nothing, I suppose, but for a few bucks more I think you can do much better with a lightly used unit from a know manufacturer like ICOM, Yaesu, Alinco, Motorola, etc.. The other thing is their claim of 8w. I'd be very leery of the claim. It might actually output that, but I wouldn't trust it to do so for long. For reference, I had an Alinco DJG5 walkie. Heavy sucker, most of which was heat sinking on the finals. At 5w it would get uncomfortably hot after just a few short Tx and would drain the optional high-capacity battery pack in minutes.
For a BOB unit, I'd be more apt to buy a well-treated used mobile rig, a mag antenna base, and a shorty antenna. Maybe even throw in a multi-section dual band stick that can be broken down with a hex wrench for bag storage (better range than a shorty). I'd likely also have a compliment of power connectors... at the very least one with gator clips and the other with a lighter plug. Gives you the option of going full mobile or rigging it direct to a 12v source (car battery, tool battery, etc.)
Also, have you dealt with amateur radio before? If not, you may not be aware that HAM/Amateur is not like CB. You don't just turn the dial to a channel and talk. Knowing how to program the radio and operate within comm system parameters requires specific knowledge. It's neither complicated nor complex, but it is necessary.
