My understanding is that 50 KHz will give slightly better sonar readings in deeper water (over 100 feet)
If purchasing Dual Frequency or Dual Search, units running at 83/200 kHz will be best for freshwater and inshore saltwater anglers. Offshore anglers should opt for units with a 50/200 kHz configuration.
Most of the sonar units that we sell accessories for operate at 200 kHz (kilohertz). Some are dual-frequency capable, meaning they can use both 50 and 200 kHz transducers. And a few new models are dual-search capable, allowing for both 83 and 200 kHz operation. Typically, high frequency (200 or 192 kHz) sonar units provide the best resolution and definition of structure and targets. They excel at showing minute details of the underwater world. 50 and 83 kHz frequencies have much greater depth penetration capability, but show less definition.
