The xplorer and the scout are two very different animals. The xplorer does much more than tell you if "there is power on a freq". It has a speaker, so it does actually receive and demodulate FM signals. It's a near field test receiver, not a frequency counter. Makes it really easy to know if you've got the correct signal or not. Not to mention it decodes, displays and records DCS, CTCSS, LTR and DTMF instantly. As far as the bullshit is concerned, you can have it set to ignore certain ranges, and a $10 FM trap (88-108) takes care of broadcast stuff or its images from making problems. Of course all of this comes at a cost so if you're just looking to play it's probably not a wise investment.
Who says you have to get a brand new VX-7? I personally like the VX-7 because of the wider receive and the 2 extra transmit bands. The Channel Counter feature is just icing on the cake. Not everyone will have a use for the extra capabilities, but I do. To borrow your analogy, if I can find a multitool that will do the job, why would I spend extra in the long run to buy the individual tools? I would just end up with more tools in the toolbox and more money out of my pocket. Dozens of models will work, not just a VX-7 or an FT-50. You could get an old Bearcat from Value Village for $10 or a 20 year old dual band HT off of eBay for $40. That'll do the job for most analog walkie talkies businesses tend to use.
