[QUOTE="PhaseTech, post: 496792, member: 3149"] Not exactly. When you flick a DD into Mono mode, instead of just the right hand Rx winding doing the receiving, the whole coil or more accurately the Tx and Rx windings both receive. So your resultant search field would be a little wider than half the coils diameter. It may be closer to 25 x 16 or so.... This "pseudo mono" mode of operation can produce some interesting results, and has over the years, but it's effectiveness varies depending on what DD coil you are using. Every time I put a new DD coil on, I play around with the Coil/Rx switch as well as different timings to see what it might be capable of, as it is extra functionality you have (on a GP or GPX) which you don't have when using a Mono coil. Now, as Mbasko mentioned, the 25" X-Search is half flat wound, half bundle wound, so when using Mono mode, you are getting a bit of that flat wind efficiency in the Receive pulse. So I guess it makes sense that Mono mode on this coil will perform a little different to what we've come to expect from a traditional DD coil. [/QUOTE]
