eotech zero loss with battery change?

[hokieglock]

just wondering if i have to re-zero now. thanks

I don't see why you would. You don't have to dismount an Eotech to replace the batteries.

I never once had to rezero the EOTECH, M68, or any other optical on my M4 while in the military upon changing the battery.

No need... the adjustments that you made on your EoTech were not stored in a "memory" so by changing the battery's nothing is changed in terms of your adjustments.

I wasn't even thinking in terms of electronic memory the first time I read it. I was thinking that the OP was worried about bumping it out of zero while changing batteries. I now see that a person would be concerned with it being like a remote control that loses its memory. But the controls go to a definite stop point indicating it is a mechanical adjustment.


I am hoping it holds its zero when I remove it, since I remove it to clean the upper and the barrel.

Removing the unit from the upper receiver can and will most likely result in a loss of zero. On few occasions I have had a buddy of mine take his off and he maintained his zero at 100m.

I haven't been so lucky. However, taking the upper off of the lower won't result in a zero loss b/c of the fact that the sight is still attached to the upper.

That stinks. I'll have to double check my zero. I like to take it off because I clean the upper upside down using one of those big red chamber guides with the holes for dumping liquids and stuff down the barrel. Sometimes some liquids find their way around to the ejection area and ooze towards the EOTech. I didn't want to use a copper solvent or something that would ruin the EOTech if it managed to find its way into the unit. I suppose I could just try to be more careful. I'll check it after I decide on whether I want a 3x magnifier. Thanks for the heads up on that.

i was more worried about the electronics reverting to some factory setting when i replaced the batteries. i never remove the unit even for cleaning.

Red - you do know that your eotech is waterproof up to 33ft unless you splurged and purchased the more expensive one which would add on that depth of up to 66ft. But it is best to keep all liquids away from the unit like you stated.

I was thinking that, but I thought someone said to keep copper solvents away from it. I rarely use copper solvents, but you never know. I wasn't sure if CLP could seep into the housing even though water cannot. I'll probably leave it on from now on.
