Diver's needs/wants

Idea 1 - Underwater application for divers 

Previously idea was about created an application that for user taking picture and this application give information (fish identification) straight on the spot after photo shot of the fish. 

Question: it is a need for divers?

I have asked some of the divers (Open Water Divers, Advances Divers, Dive Master and Instructor) about this. 

: Assume that you can bring your smart phones underwater and take picture. Using this "fish id application" to identify the fish that you don't know.

All of them answer were "YES"

WHY?

1. Diver will curious about what is the fish identity when they first saw the creature

2. Diver would forget how the fish look like after the dive (if find the id later on after diving)

3. It was cool that diver can get the information on the spot (No need look for books, online or asking around for the fish id)

4. It was hard to describe to people that what you seen and what others can't (you might not get the answer because sometimes hard to describe, other than a picture!)

Other than divers, I asked few people that like to go to the beach for snorkeling. Not only diver can see fish underwater down for 10m but snorkeler can find a fish around 2-3m. 

All of them answer a "yes" because they curious what the fish identity. They anted to know more about what they see underwater.
