Hello all,
I am working with a nonprofit that would like to purchase an updated GPS unit. It is a small botanical garden in Central California. They are looking for a unit that is easy to use for the volunteers. The other option would be a good app for volunteers to download on their phones and purchase an receiver. I have seen the Bad Elf 2300+ and the Garmin GLO but have no real data about how well they work, particularly with a mobile phone. It would be best to have a unit that would work with both Android and iOS devices.
