GPS for OPA and SBI
 

We are looking at purchasing a gps system for OPA but we also wants to run some SBI races. Can we buy the same set up for both organizations? We rented a gps at lake race but need to make a purchase before the next race we make. What are everyone's suggestions? I know everyone turned in a chip after the race to be scored. Does SBI do it the same way?

No SBI uses Garmin GPS the models are listed in the rule book
