Warning - Beware of imitations: what looks like a bargain may turn out to be very expensive useless device, as the low price of an imitation may mean less power, less effectiveness and reduced safety.
Does a cheaper clone of the DAZER made in China work as well?
The differences are -
- DAZER II utilizes a full 25mm transducer to produce sound vs. the clone we've seen uses a 12.5 mm transducer.
- Less dispersion of sound obviously will produce and less range and less power output.
- DAZER II produces a sound level of 115 dB, while the clones we've seen output about 105 dB (Remember: for every 6 dB there is a required doubling of power output).
- DAZER II uses a self-diagnostic circuit, that means we actually monitor the battery output to assure optimum performance whenever it is used; plus it is tied directly to the output and can assure that sound is being produced. The clones we' ve seen use a cheap straight circuit that simply is equivalent to a flashlight. It keeps putting out sound on an ever decreasing curve, therefore you can think it working at top levels but it is not and will be at low levels.
- DAZER II is powered by a 9V alkaline battery (RAYOVAC) that is included; the clones we've seen use cheap carbon zinc batteries. Yes! DAZER II unit comes with a 9V battery so the Dazer is ready to work from the moment you receive it. The importance of the type of battery is tied directly to the power level of the output, the higher the output power, the higher quality battery is required.
