I don't have any info about whether the unit is legal for field trials at this time.I lost all my dog equipment in the massive praieie that totaled every thing period.The Laelaps sounds like a simple unit that is reasonably priced.It is compatible with my smart phone and has good range and dependability.I lost Certified Sam to the fire which was a winning wild bird dog that believe me could run with any dog.I won't be running in any trials but still working a dog or two.I do have a son of Sam and might get him ready as he is a class dog for sure.
I thought this reasonably priced unit might work well for just training and like to know of other owners and their experiences with the unit.
