Looking for a Older Pulse (PI) detector testing

Does anybody know if Fisher ever made any Pulse Induction detectors way back when?? (along with model names?)
I am looking to do a few side by side test on small items in various beach/sand conditions.


Don't want to spend more than a 100 or so, hence an older model.
Many thanks!

Nov. 20th, 2010 ***** Thanks Kieth and Tom!

I just picked up an older (foster version) Sea Hunter.... This machine is JUST to get me started in the horible black sand/iron rich beaches we have here in certain parts of Northern California.
When Tom comes out with his version of a pulse unit, (The AU-42 right??) I will have been in the posistion to acquire his machine... or an Aquastar that I can hire somebody like Tom to do a sysytem run through and modify.... Thanks again!!!

Fisher had the Impulse but I dont think you can get hold of one for 100.00 dollars..I bought a Garrett sea hunter P.I. for 50.00 that worked but no real depth ...Older Garretts seem to be the cheapest though ..

I believe you will find the older pulse machines ( 20 Year old tech) are not very sensitive to smaller type targets..The newer ones are more advanced for the smaller gold...

Lower (Shorter) delay will get some more sens. to low conductors like below 10uS ..Some older ones can be modified for this!

Good luck

Correct. Fisher Impulse. Very popular 15 years ago.
