To Build or Buy?

[Terry]

Hi. I am new to this forum and do not have a terrible amount of electronics experience under my belt.


Can one build a better detector than what can be purchased commercially? For underwater use?


I would love to build a detector but don't know where to start.

A pulse induction unit, maybe, but not a target I.D. VLF type detector. PI is what you want for underwater, but making everything waterproof is another challenge.

Carl, we have been building and using underwater


camera housings with strobes and such for over 35


years. Water proofing is not a problem today. I


agree that PI is the way to go, also getting back


to the "click" type of indicator, rather than the


continuous tone is much better for UW work.

Maybe you can offer some info on how to make or where to get good waterproof housings. I have no knowledge in this area. Also a source of waterproof sound transducers.

Yes, I agree.
