I realize that I am way over my head with the technical minds that are occupying this forum. The needs of the end-user must be a part of the creators imagination and goals. You want your products desired and we want them if they fill our needs. With that stated I want to express the a couple of 'needs' of a
 
Hi Frank,
One solution is to have the detector sample the signal at two or three points i.e 15, 50 and 100us. Run these signals through three channels and have three distinct audio tones. This does away with any switches. Has this been done? Yes, I made a waterproof detector called the ProPulse using a three channel receiver and doing just that. Mike Robinson evaluated it in the US, and, although he did very well in the six months he used it, he couldn't really get on with the three tones. I think that he problem may be that there was not enough difference in the audio frequencies. They were 1.5kHz, 750Hz and 375Hz. I think that just the first and the last would have been more useful. Also, very weak signals just above the threshold are difficult to determine as the threshold noise causes all three tones to burble up and down. Anyway, I still have the electronics, so further experiments can be done.
Eric.
 
I agree that those tones that close together and my ears (gunbunny in the Army 105 and 155's) would be hard to differentiate, but tones would work for me. The most problem I have is not having 3 hands. However with the CS7 I used my thumb to turn the knob of the micro-processor but with the HH
 
I agree that those tones that close together and my ears (gunbunny in the Army 105 and 155's) would be hard to differentiate, but tones would work for me. The most problem I have is not having 3 hands. However with the CS7 I used my thumb to turn the knob of the micro-processor but with the HH PI the letting go of the rod or the scoop is the choice and that is the problem. The system works on the CS7 and the HH PI it is just the "user-friendly" part of it is not advantageous when underwater. From reading on this forum and only understanding little from the composite of intelligence you have provided with this forum I know that PI Disc detector is just around the cornor. However I wanted to in inject my input from a "user" standpoint hopefully to be understood and hopefully considered.
So not to appear to be as inept as I truly am, I went back and re-read your answer to me and it may be you were telling me you could build a machine and have built a detector that sampled at 10, 50 and 100uS internally with three tones to acknowledge the sampling of each, no knobs to turn. If you are stating this in that manner... I am ready to purchase such a machine and I hope that is what you said.
I appreciate your help, your forums format for advancing PI detectors and the spirit of the individuals participating.

P.S. Mr. Bill, If he will build it get ready for a phone call....
 
Hi Eric
The SD2200 tends to be like that,in so much that you are listening for a different tone.Regards Frank Wallis
 
Frank, I can't help much with a technical solution but as a fellow water hunter, I have improved the hands free situation by putting a tether on my long handled scoop. I use a stainless steel snap shackle with a 6 inch length of cord attached to the scoop handle. My dive belt has a 'D" ring to snap it onto and leave a hand free. The 'D" ring is really a hammer holster. Both are available in a hardware store. Works great.
 
Does the scoop stay behind you? I have a problem in current of it trying to beat me to death. What or where in the ocean are you working, Gulf side has hardly no current. Frank
 
Sorry I took so long to reply. I hunt on Florida's east coast (Atlantic Ocean). Don't have much trouble getting beat up by the scoop. The short tether arrangement keeps the butt of the handle close to your dive belt. It can pivot around you somewhat but doesn't run into you. You are more likely to get your shins barked while untethered and digging. Gotta watch those waves!
