This unit is compatible with any detector that has a 1/4" audio jack.
The B&Z booster/speaker combo is a great addition for running external speaker set-ups, with more than enough grunt to run dual speakers if required. The kit consists of one booster with batteries, and one speaker as pictured above. It runs off it's own power supply of 2 x AAA batteries and is therefore compatible with all detectors that have a 1/4" headphone socket including the Coin/Relic detectors.
The booster has a 1/4" jack that is used for a single speaker (or a pair of speakers wired into a common jack) and a plastic clip on the rear to allow it to be fitted onto a harness or strap. Additional speakers are available on request, and a dual speaker setup is also available to directly plug into this booster.
The bypass switch dulls the switch-on spikes and allows for some secretive detecting if there is unwelcome company or the volume controll can be turned down low for the same reason. The volume control can also be used for windy days etc.
The B&Z booster now comes with a detatchable lead from the battery to the booster. There is an additional jack on the top of the booster where the lead plugs into. This allows for a quick replacement or repair if the centre wire in the cable is broken by stretching or from flexing.
This booster is available as a booster only, with a single speaker, or with a dual speaker set. Select your preferred option from the choices. The boosters now have a curly cord for the input lead which makes the booster more versatile.
Get a B&Z and you don't have to replace your booster when you upgrade your detector as you have to with some units.
