Nikon compatable flash guns

For the past few years I have used a Hanimex TZ/1 flash gun which has been thoroughly reliable and produced great results. I would like to continue using the TZ/1 but in both the Nikon user manuals they warn against using flash guns which have reverse polarity or generate high voltages.

I have contacted Nikon to ask if the TZ/1 is safe to use but they have been non commital on the issue and I suspect that they are encouraging me to invest in a Nikon Speedlight which will cost at least £150.

The TZ/1 is a simple piece of kit, using four AA batteries and is controlled by a thyristor. I will be very grateful if you could advise me on the compatability issue as I obviously don't want to damage my new cameras by experimenting.

I look forward to your reply.

And, as Nikon manuals frequently note, "[n]egative voltages or voltages over 250 volts applied to the camera's sync terminal could not only prevent normal operation, but may damage the sync circuit of the camera or flash." So, you need to know the trigger voltage of that particular flash.

While Nikon is loathe to give any info about Nikon compatibility with other manufacturers, some times comparing their own equivalent to your equipment might help, say an SB unit of some kind with the D50.

Here's a link to the searchable Nikon tech support database you might find useful: http://support.nikontech.com/cgi-bin/nikonusa.cfg/php/enduser/std_alp.php?p_sid=1hOC4_fi

And...Check with the strobe manufacturer for voltage specifications
As I recall, there is an adapter available that will mount to your hot shoe that will block hot voltages from your strobe which, at that point, needs to be used with a PC cord and will likely eliminate some of the cameras automatic flash features. Kind of a trade off.

Take it light.
