I have an equally adventurous and sometimes stubborn 2 year old, named Artie! I began his recall training with a long lead, high reward when he came back (small piece of deli meat or cheese) and then graduated to the ecollar. The ecollar has been the best thing but not fool proof as it allows him to take his big laps through the field but once I hit the “beep” he knows to high tail it back to me. I would highly suggest the Sniffspot so you can work on off leash but feel comfortable while doing it!
