QUESTION IS CAN A ROMER ABSOLUTE ARM MODEL RA-7525. Can you add a laser scanner to it somehow or do you have to send back to Hexagon and have it upgraded to a RA-7525 SI or RA-7525 SE.Or it can NOT be done and I have to trade it in for a RA-7525-SI OR RA-7525-SE
You cannot send it back to Hexagon and have it "upgraded" to an SEI but there is a laser attachment that can be added as a probe. You would need to contact your local Sales rep to get your hands on one.
