Used Stereo Optical Vision Tester Optec 6500p. The unit powers on but I believe it needs a remote I am not familiar with this type of equipment I recommend the buyer to be familiar with the unit. Normal sings of cosmetic wear, please see picture number 6 in the left side of the unit you can notice that broken part however this does not affect the operation of the equipment. The unit its sold as is I am not sure if it full functioning make a reasonable offer. Power supply its included in this sale. Any questions feel free to contact me. Thank you.
