Hondex HE-773IV-DI 290kHz Automatic Sonar

The Hondex HE-773IV-DI sonar has been designed to meet the requirements of skipper operating small inshore fishing vessels and who require a cost-effective, comprehensive sonar solution. With multiple installations now completed in Scotland, England and Ireland, Echomaster Direct can report that feedback has been overwhelmingly positive for this exciting new addition to the Hondex range.

The HE-773IV-DI incorporates a user-friendly menu system with multiple display modes, to suit a wide range of tasks. The full circle scan mode allows detection of fish schools at any bearing around the boat, whilst the vertical scan mode displays a cross section of the seabed and any fish schools within the 180-degree profile angle selected. Echosounder Mode allows the HE-773IV-DI to be used as a conventional echosounder, ideal for fishing in shallow waters.

Unique to the HE-773IV-DI is the 4-display mode where 4 separate sonar pictures can be displayed each with their own range/tilt settings, allowing the operator to see if fish are going deeper or rising to the surface.

The ultra-compact sonar is available in either manual or automatic versions. Both are supplied as standard with a 1-meter sonar tube. Alternative optional lengths are available meaning that installations can be completed on most types of fishing vessel. Echomaster Direct can provide guidance on installation requirements and possible solutions, please contact us if you require any assistance.

The TD303's 290kHz frequency will provide a much higher quality resolution of image when compared to a traditional 200kHz frequency and is ideal when searching for ‘bait fish’ including sardine, mackerel, herring and anchovy. With a lower frequency range of 140-240kHz, the TD304 customer can expect a longer detective range which is around 1.5-2 times greater than the TD303, but with this comes a slightly lower quality resolution of image.
