I was WRONG!!!! I have to correct these statements that I made above. I eyeballed it before punching. Then even when in the tank I must have been in a dim light and couldn't see those itty bitty holes.
The holes are just high enough to work in a lavatank and probably similar tanks. I have both a Fusion and Platinum Punch each in a lavatank and the holes are right above the bottom cap. Cool!!!
Not that I need the holes because I have two punches. But, I'll probably buy them anyway.
These things rock!!! Thanks Isaac!!!
