Slave triggers.

I have two remaining flash units left,
1. A Pentax 160 Sa.
2. A Centon FH 75 with a pentax module.
I believe that the pentax flash can be used on my Samsung gx 10.
The Centon I am unsure about, ref. trigger voltage, etc.
So, can I use these with a slave trigger and which trigger would be recommended?
I would also prefer to use the pentax flash with a bracket on my camera.
Any tips, advice and warnings would be welcomed.
Regards,
Rex

Ebay has flash triggers. They generally work fine, but are so cheap it might be worth buying two to have a reserve.

If you are serious about this, I would upgrade the guns to get more power. Under-powered flashguns are a pain to use.

ETA: Early Centon units had high voltages. The 85 was fine. I couldn't find out anything about the 75, but measure the voltage yourself.

I have just been searching through the net and came across this item, i-Slave, an intelligent trigger.
My problem is that I am new to digital and quite honestly I am very often baffled by this new technology. I was a film man for 50yrs. I have used remote slaves with film but that was years ago and I am now re-inspired to use a camera again.
The idea of the slaves will be for close up work and some macro, some portraits but not from a profi point of view. I do however wish to turn out decent work. I prefer off camera flash
The Pentax and Samsung flash units seem so expensive around £180. Maybe this is an old mans view.
However I may have to bite the bullet and maybe go for a new flash and use the present ones as slaves.

Many people prefer manual flash for macro work.

Try this:

Amazingly, having updated the old unit so that it had a low voltage, they called the new version the 285HV. Incredible. Anyone with more than two brain cells would have called it the 285LV.

ETA. Perhaps they asked Pentax Marketing to suggest a name.

What I really wish to do is, use a flash unit on a bracket to the side of the camera and a lead to the hot shoe and an independent slave flash to back light or whatever. I do not subscribe to the school that blasts the macro subject fully frontal.
I will be using manual flash. Thanks for the prompt George,("Many people prefer manual flash for macro work"). It took a while to work out what you meant. I know that senility is here.
In retrospect, when using manual flash I will not get the pre flash problem. So I have wasted your time but, the egg on my face is hiding my blushes.
