I know this has been covered before but, How do you tell Type R from GSR from SiR cams?
I have a few cams and need to know which is which, Tried the seach.
Thanks.....

 

..... mic them.

 

if im correct i belivve the itr cams have 2 rings/slots on the end. i think.

 

Thanks for the replys.
I can mic them , what is the lift of the GSR, Type R and the SiR cams.

 

if you look at the end of the cam there is a little 3-4 mm part of the cam that is a perfect circle. the itr and ctr cams will have a slight roundness to one or both the corners of that 3-4mm section.

hard to explain without pictures.
