Ferreting, the importance of getting your ferret back 

Using the Ferret Finder.
To start off with, I ensure all of my collars are fitted with extra holes. They will then fit every ferrets' neck. These change between ferrets and their physiological state at differing times of the year. I also carry a battery tester so I can see what charge is in the batteries as this will effect it's calibration and it's 16ft range. Although the MK1 still has many admirers, the differences between the Mk1 and the MK3 are sizable. The MK1 was terrible for picking up interference, especially metallic. The MK3's internal anti-interference capabilities along with its accurate LED readings make it the set to use but it does have a sound that a lot of ferreters don’t like. To deal with this, a later addition of a pitch finder on the receiver acts like a volume control but I feel that the pitch of the tone is the secret to location. The main difference when working it is the LED meter rather than a wheel like the MK1 had. It is either 4ft or 5ft not in between, unlike the adjustable wheel.
The fitting of the collar is also important. The transmitter must be under the chin as it's signal is egg shaped thus effects accuracy, also, this must be taken into account as many ferrets are on their side when scrabbling at a rabbit in order to try and make it turn and bolt.
To state the obvious, to use this device correctly the ferret must first be stationary, as trying to locate a moving ferret, unless aufait with this set is hard. Switch the finder on, place on search and hold outright like a pistol. It's just like playing hot or cold and follow the signal until it is 8ft or under. Switch the device to locate, change stance to upright like a cup and pin point the location in the same manner, hot and cold pretending to place the finder on the corners of an imaginary two ft box. The signal and pitch will tell you when you have gone too far and you need to this until wherever you place the finder the signal is the same, it should be a 1ft box now. Once the signal is the same in the corners you have the sweet spot to dig.
