8/10/17 Report - Metal Detecting for Watches - How Mode Selection Can Really Affect Results. More Active Hurricane Season Predicted.

Written by the TreasureGuide for the exclusive use of

Watch Under Coil of Ace 250.
See video below.

After about a hundred hours and a thousand failed attempts I finally found a way to get my video uploaded from my new video camera to YouTube so I could post it here.  I was not able to upload it directly to blogger for some reason.  Things that should be so simple can be terribly complicated.

The video shows something I talked about yesterday.  It shows how you can miss items such as watches if you are not careful.  In Coin Mode, when sweeping the Ace 250 coil parallel to the face of a watch, you will get no signal or a poor signal.  When sweeping perpendicular to the face of the watch, you'll get a pretty good signal.  Of course the ID meter will not tell you that the object is a watch even when you get a good signal.

The watches used in the video are first, A Malibu Polo Club watch (maybe a knock-off), second, a Seiko Perpetual Calender, and third, a heavy Seiko Couture Kinetic Perpetual.  All are fairly large men's watches.

There are a few points that I am illustrating.  One is that the detector signal from an object that has an irregular shape, such as a watch, can result in a different signal depending upon the direction you sweep the coil.

Another point I am reinforcing is that it is easy to miss some very good targets if you are not very careful.  The mode you use is important.  You might not think anything of using Coin mode or Jewelry mode, but it will to some extent determine what you will and won't find.  That might sound obvious, but it is easy to unintentionally miss good things and not realize it.

Watches differ a lot.  Some cost thousands of dollars and can be made of platinum or gold.  They can be made of a variety of materials.  The band can be made of one material, the case another and the workings another.  That can all result in different types of signals, which can make it very difficult to identify something like that from the signal.   I don't know of a metal detector that can correctly identify a watch.  They can be very desirable targets, yet very easy to miss.  If you've been following my blog very long, you know that I often warn of the dangers of discrimination and target ID.

Here is the link for the video.  I hope you'll take a look.

I think that is a pretty dramatic illustration of some things I've said before.

You might say, "I wouldn't be using Coin Mode if I wanted to find a watch."  That might be true, but do you really want to take a chance on leaving a Rolex in the ground when you pass right over it even if that is not what you were looking for?  As you would expect, different modes respond differently, but the question is do you know exactly what the different modes will or will not do?

Another thing I'm showing here is how important it is to really know your metal detector and how it will respond (or not respond) to different types of targets.

I actually used more watches when I originally did the experiment, but cut it down to three for posting.   There were slight differences in the signal for each watch, but they were generally similar.  Some varied more than others.

Another variable I didn't illustrate is how the signal is affected when the band is more open or collapsed and when the watch is laying flat.  I'll show more some other time.


Forecasters now say there is a 60-percent chance of an above-normal season (compared to the May prediction of 45 percent chance), with 14-19 named storms (increased from the May predicted range of 11-17) and 2-5 major hurricanes (increased from the May predicted range of 2-4). A prediction for 5-9 hurricanes remains unchanged from the initial May outlook...

Here is the link.


The weather shown above won't affect us much anytime soon, although we are going to have a small increase in surf this afternoon (Thursday).  It will only be 2 - 3 feet though, then decrease again.

The one shown farthest east is one to watch.  It might strengthen this weekend and hit somewhere in the Carolinas.

That is it for today.

Happy hunting,
