I got one yesterday and noticed the fish going after the dot. Good fun. Don’t go blind.
do you have to be certain distances to read the proper readings of certain objects ? someone else made a video checking a cup of water from 1 foot away then 2 feet away, ect. Each distance gave her a different reading.
Is pretty neat my buddy uses those I’m wondering are they FDA certified?
Yeah thats the shit bro… I can check all my tanks from my chair at the computer.
