I tried posting this one to the general forum, but didn't get any responses. Hopefully this is a more appropriate place for this, and someone will be able to help me out.
I am a graduate student, studying humpback whales off the coast of California. For part of my thesis, I am measuring the width of the flukes (tail) of these whales. To do this, I plan to attach two parallel lasers (of a known distance apart) to a camera, then to use the distance between the two dots in the photo to calculate the width of the flukes.
So, I am looking for recommendations of laser pointers that will show up in full daylight (just the dots, not the beams). Because I will be pointing these lasers at animals, they have to be <5mW. I would prefer a constant on/off switch, and it would be helpful if it was waterproof/shockproof as I will be using it on a boat. Does anyone have any suggestions for me?
I've been looking at the Z-bolt BTG-10G, but my funding is limited and I would prefer something cheaper if I could find it. I appreciate any advice or info you guys can give me.
