Common Concerns Answered
Will this transducer work with my older Garmin 6-pin sounder?
An adapter cable is required to connect the 8-pin Garmin B117 to older Garmin sounders with a 6-pin connector. This is an additional purchase that should be factored into your overall cost and installation planning.
Is the installation process difficult for a DIYer?
Installation involves drilling a precise hole through your hull and requires careful sealing to prevent water ingress. While instructions are provided, achieving a watertight seal is critical, and many boaters opt for professional installation to ensure integrity.
Does the 50 kHz frequency create too much clutter in shallow water?
Some users have noted that the 50 kHz beam can be quite wide, potentially leading to some data clutter in very shallow water conditions. Adjusting sensitivity settings on your fishfinder may help mitigate this.
