Re: Your opinion on this zapper please

>- If for example a parasite vibrates at 40khz (random number); which zapper would do a better job, a zapper that is constant 7 minutes at 30khz, or a sweep zapper that sweeps between 25 and 35khz for 7 minutes.

In my experience, a step zapper will produce the best results but this requires extensive zapping time which is not practical for most users. A step zapper is going to produce several different frequencies but will hold each one constant over a sufficient period of time. Otherwise, a dual fixed frequency zapper is sufficiently effective.

In our testing of various zapper technologies, we found that the ones that did not produce a constant frequency produced reduced results with several of the parasites that we tested with. In theory, sweep, wobble, and similar functions look attractive. The problem is that companies that go for these technologies do not test to see if their product is really effective. At minimum, every zapper should be tested with in-vitro specimens of specific parasites and the times for 90%, 95%, and 99 % kill recorded.

>- Sweep zappers might not keep at a certain frequency for long period of time but are continuosly on.

Generally, the longer time that any zapper is on, the better the results. Why do this if a regular zapper is going to do the job?

Good Zapping :^)
