It's a pretty user friendly system, I am involved with it from the enforcement side of things.
Register an account, print your permit, and sign into training areas prior to heading to the field.
Make sure to carry your printed permit on you while recreating. Every person age 16 or above with you needs to have a permit. My advice is to sign into every open training area in the area you plan to recreate, that way if for some reason you want to deviate from your plan in the field you are good to go.
The GPS map app is a nice tool; the iSportsman website also has copies of FWA regulation 190-13 and regulation supplement available. Definitely read those before heading out.
PM me if you have any questions or comments. 353-7535 is our conservation officer duty phone. If you're ever in the field and have a question, or see something suspicious, give 'em a call.
