* The Deluxe Receiver now features an in-built stub aerial that gives the receiver extra range and it now uses 2 AA batteries. This small change means that the unit has longer working life on each set of batteries and it also helps to increase the workable range of the receiver, improving the signals penetration of foliage. * The casing is still the same high quality soft touch finish and is now fully waterproof! * Significant improvements to the electronics mean that receiver now has 10 independent channels (twice that of the standard receiver) and each channel can be programmed to a different tone output; selected from the 21 tones available. * Volume is adjusted through 10 setting using the SSI (Silent Step Increment) system, controlled by the ‘+’ and ‘–‘ buttons on the side of the receiver, with the volume being indicated by the LED display on the front of the unit. * You still have the choice of Vibrate on/ off, but this is now complimented by the vibrate mode automatically switching on when the speaker output is reduced to silent. * Another really nice improvement is that the first bleep is no longer a ‘double bleep’. * Finally, the receiver is supplied 7 colour lenses (5 fitted and 2 optional colours), with all the colours available to purchase for those anglers that want to customise the colour array they are using.
