Pulse Dtetectors

[concad]

I am looking to purchase or build a pulse detector. I have a Garrett GTAx550 and Detector Pro HH Diver. These units do not have the depth I need in salt water or surf condition.

1) I am very good a building things and have a lot of tools, but have never done any major circuitry work before.
2) What is the comparitive cost of building vs. purchasing.
3) What level of performance can I expect compared to commercial products at the various price breaks.
4) How readily available are parts.
5) I always see update and swap out of certain peices, how will I know this.

You get my point from my questions.

Oh ya I will need to make it waterproof also.

Thanks

Hi,

My own comparison between buying new versus homemade...

Re: White's 6/DB homemade project (analog w/GEB & disc)...
New (?): $600 - 800 (uncertain - I never bought one)
My homebrewed cost: $125

Back about 1982, somehow I obtained the schematics and PC board layout for the White's 6/DB. I worked in an EE R&D lab, so I ran a copy of the 6/DB circuit board in my spare time. I visited a couple hamfests to buy parts, as well as mail order parts, to finish it. After all of the parts were added, the homemade unit cost about $125, and $50 was for the OEM White's coil. After debugging the board (which appeared to have intentional errors to confuse copying*), it worked perfect - very well in fact. Paid for itself fairly quickly.

Now I'm looking into a homebrew PI detector.....

(*) Some repair manuals intentionally include errors to their "published" circuit layout, to confuse those who intend to copy their boards & units.

There are plenty of projects here -> http://www.geotech1.com/cgi-bin/page...e=projects.dat
