A while back I bought a backup DS51 and it came with a "TTL Slave" sensor. This is a similar case to the EV Controller but is light gray in color, has a Min-Max adjustment and takes a battery.
Even though it's called a "Slave TTL" or "TTL Slave", I suspect that rather than being TTL, it's closer to the "Auto" or thyristor control from pre-TTL days. If so, that would be ideal for use as a slave trigger in caves. Can anyone confirm that it works that way and do you know what type of battery it takes ?
Thanks.
Steve.
