b. Detection Range
Your CSR1 is a top performance deep seeker but adverse soil conditions can significantly reduce the depth of
detection. Detection ranges will vary depending on the size of the object, the length of time an object has been
buried, and the type of ground the object is buried in.
The best ground conditions are well compacted soils and coins can be found at the greatest depths if the object has
been buried for some time and the coin has interacted with the salts in the ground, thereby appearing larger to the
detector. The worst conditions for detecting are on loosely compacted or freshly dug ground or when the object has
only recently been buried. In these conditions detection range will be reduced. 90% of all artefacts are found within 6"
(20 cm) of the surface.
c. Determining Target Size & Depth
An operator who is familiar with his instrument will be able to do an excellent job of determining object size, shape,
and depth before he digs. This technique is learned from careful analysis of the radar and audio signals coming from
the detector. Each time a signal is heard, listen for any peculiar characteristics it may have, determine over how large
an area you get a detector signal, and try to "outline" the object before you dig.
After digging up the object, compare the object size, shape, depth and position in the ground with signal information
you received before digging. After careful analysis of many digs, you will learn to "read" the hidden target before
digging.
d. The Importance of the Right Approach
Treasure hunting can be a profitable and rewarding hobby, if approached in a patient and diligent manner. Time
spent researching to locate a worthwhile site for a search can be time wasted if your search is hasty and erratic. To
achieve maximum results, it is important then to decide on your approach to any particular site in advance of the
actual search.
Tactics will be decided by the type of site - it is more profitable to scan a small area thoroughly, than to conduct a
haphazard search of the total site. However, when the site is too far away for you to make several return visits a plan
should be adopted which gives maximum site coverage, at the same time as indicating the most likely area for
detailed search.
Your detector alone is not a guarantee of successful treasure hunting. Any detector needs an operator and for the
best results the operator needs the right approach, attitude and technique. Too many beginners neglect the
importance of pre-planning and research before using their detector in the field, and patience and technique during
the actual search.
A successful search should begin with research sometime before the day of the actual search. The extent and
thoroughness of your research will be one of the major factors in the success of your detecting. You should aim to
get as complete an understanding as possible of the local history and geography.
The key to the choice of the site is to think of people, where they congregated over the past few hundred years. What
were their customs and pursuits? Where did they spend money? Where did they carry money? The answers are not
Roman sites, nor are they associated with mystic treasure stories of crocks of gold. Rather, they are unassuming,
non dramatic places, like public footpaths and ancient rights of way, old houses and so on.
When you have chosen your site, allocate a whole day from early morning to early evening for the search. Make sure
that you have all the equipment you are likely to need. Your detector should be checked before starting out, and you
should always carry a spare set of batteries. You will also need a strong, sharp trowel. It is also a good idea to have
a set of lines and pins so that you can lay out your search area scientifically.
Most beginners make the mistake of rushing about hoping to chance upon a rare find. If for example there happened
to be a valuable ring that was buried 41 deep on the site you were searching, it you rushed about haphazardly and
quickly on the site, the odds would be very much against you finding it. On the other hand, it you pegged out the area
scientifically and searched slowly and thoroughly, the odds of finding the ring would be much more in your favour.
