ARS 17-101(11) defines when you're a guide. If you're a guide, you need a guide license (ARS 17-362).
11. "Guide" means a person who does any of the following:
a) Advertises for guiding services.
b Holds himself out to the public for hire as a guide.
c) Is employed by a commercial enterprise as a guide.
d) Accepts compensation in any form commensurate with the market value in this state for guiding services in exchange for aiding, assisting, directing, leading or instructing a person in the field to locate and take wildlife.
e) Is not a landowner or lessee who, without full fair market compensation, allows access to the landowner's or lessee's property and directs and advises a person in taking wildlife.
So, if you do any of those first four (a-d) you're a guide and need a license. I'd say trading for bonus points is in a grey area for a, b, and d. Problem is, the law doesn't define "guiding services," "for hire," or "commensurate with the market value" anywhere as far as I can tell.
I'd argue that helping your buddy hunt isn't a "guiding service," working for bonus point sharing isn't "for hire," and that bonus point sharing isn't "accepting compensation commensurate with the market value...for guiding services." You can probably see that AZGFD might see things differently.
But, like has been said above, you probably won't have to deal with it unless your bonus point buddy bags a toad and tells all his buddies what a good guide you were.
