So I went out on my first night dive last night after finally getting over a nasty cold. Got my C8 eLed & my Mini40 eLed light and feel like I'm all set. The Mini40 is my backup and it's attached to my mask strap so that if I have a failure on my primary I can immediately reach it.
As we are in the water and swiming out to I test the Mini40 of course and turn it off by twisting the lens just enough to get it to turn off (in case I need to turn it on I won't have to rotate the lens very far, smart eh?
).
We get down to about 35 fsw and I look at my computer and don't have to touch a button to turn the backlight on. Seems that someone must be right behind me as there is a light shining right on the computer. Perfect! The mysterious stranger must have stayed right behind me the entire dive below 35 fsw because there is constantly a light on my computer whenever I look at it. Good stuff! I look around to see who's behind & above me, but can't see them. Odd.
We get back above 30 fsw and magically the 'stranger' disapears. Odd again. Couldn't figure out why now I had to use my backlight on my computer.
I finally figured out when I got home that the pressure below 35 fsw pushed on the Mini 40 enough to engage the contact. My 'backup' light was on for most of the dive.
DOH!!
Of course there was never anyone behind me!
Other than that I had a great first night dive, we saw a seal hunt some fish just at the edge of our lights and that was awesome!
Happy Turkey Day for you US folks.
