Opticstar RDF - battery included?

[emadmoussa]

I ordered the Opticstar RDF for my both my frac and Dob (a smaller, lighter alternative to Telrad).

However, I can't tell whether the battery is included? If not, is it 3v lithium (I know the Wiliam Optics version comes with this one included)?

I've read a lot about these things but never really understood how they work - or tried to find out...

Are you sure it's lighter than a Telrad Emad?
One comment I would make is this type of finder can be very bright at its lowest settings.

Similar to a Telrad,  except it's got a variety of reticules to choose from, red and green.

Maybe not lighter, but a lot smaller. Yes, it's somewhat bright, but as far as I remember it was OK. I tended to turn it off and on sometimes in order to position it accurately on the target. TBH, I do that with the Telrad as well, especially when it's a bit foggy. It too can get bright and smudgy.

What I have discovered with my RDF is that 'cheap' flat cell batteries  don't make a good job of powering my one.  If you end up needing to buy one I would recommend the investment of something like a Duracell flat cell.

Agreed.
