Just installed new FCV295 and B265LH,coming from Lowrance HDS,hoping better performance. Followed instructions setting TAP A-A both H and L ,starting 50-200 Khz ,then tried 42 and 144 same problem. Low freq signal OK but looks a bit weak. High freq very very weak signal,even at 5 meres depth,no indication of depth. tried many seting of TVG ,working only at 1 but still weak. Improved only by putting TAP at C ,then returned at A for fear of breaking something. Any Idea?
FCV295 B265LH issue
- Thread starter plexi47

I'd search around the forum, because this issue does come up a bit. Typically the best frequencies for this setup are for the HF channel to be set at 200Khz with a bandwidth of 40Khz, and the LF side is set at 42khz with a band width of 21khz.
Hope this helps, :sail

plexi47,
The transducer TAP Settings should be "A" for both the Low and High Frequency, and the stated bandwidth for the B265LH on lower frequencies of 42-65 kHz so I would leave the low frequency at "42 kHz".
But keep in mind that the FCV295 cannot transmit at the following: 53-65 kHz, 111-139 kHz, and 171-183 kHz. So, I would might try setting the FCV295's high frequency at either 160 kHz, 190 kHz, or 200 kHz and see what works best for your fishery.
When it comes to FCV295 Settings, you can change the unit's Pulse Repetition Rate, in 20 levels. Normally, the highest rate (Manual 20) is used. However, when you are in shallow waters there might be a second reflection echoes appearing between the surface and bottom echoes. If this case, you might need to lower the TX rate level.
I hope this information helps..?
