Roland, thanks for the input. After more consideration I proceeded to order a unit. Fortunately the LCD display is very easy to see in full sunshine .
I’m thinking of using a Big Red Bee 900 MHz GPS locator for my Level 2 Certification flight. I like the idea of the handheld base station receiver with the LCD display the rocket’s GPS coordinates without the need for a computer in the field. I found a free cell phone based app that will direct one to a set of GPS coordinates once entered.
