Deepstar settings.

A couple of people have emailed me on the best control settings for a Deepstar when used on the beach. I thought it would be a good idea to post the reply on the Classroom as, in general terms, the same principles apply to all PI detectors. One of the benefits of PI is that it works happily on a conductive salt wet beach where some other IB type detectors stall completely. This is because there is a time gap between the transmitter operation and the receiver coming into operation. This time gap is often referred to as the
 
Eric wrote:Many PI detectors have a Pulse Delay control brought out as a user adjustment. It may be called different things, such as REJECT on the Deepstar, or ELIMINATOR on the XL500, but the function is the same.
I am not nearly as astute as are many of you here on this forum but Eric's post brings a question to my mind. If the XL500 (as just one example) has an adjustable pulse delay control-why limit the low end range to 25uS? I understand that it is primarily a water detector and understand a bit about the effects of saltwater at depth-but would it cost Garrett any more money to make the lower limit of the pulse delay at say 15uS and allow the user to adjust it back up as needed? Is there more involved/other consideration as to whythey can't make a PI unit with a low range of perhaps 15uS and an upper range of say 100uS and then include a control to adjust as needed? That way it could be used as both a diving and beach hunting machine.
 
Has anybody had a chance to measure the pulse delay on the new Garrett Mark II, which replaces the XL500? Just curious.
 
Thanks Bill for your response and for the link to the AquaStar. Has anybody had a chance to measure the pulse delay on the new Garrett Mark II, which replaces the XL500? Just curious.
 
Hi Tom,
The XL500 electronics dates back to the early 1980
 
I haven't heard of anyone doing that yet.
If we get a few air test on different items, that should give us some ideas. US nickel would be good for a starter
Anyone out there with a Mark II ???
Bill
 
eric,
I have a deepstar since 19997, and i would like to by a new one. i would also like to know how much does it cost today an if they have had technological modification in the past few years.
Perhaps you have new deepstar with more power?
could you send me by mail informations about the price and conditions (power).
Thank you, from a french deepstar fan.
