Default HELP - Sounder Watts

Good day all

One newbie here needs a bit of help regarding sounder
wattage. All other variables being equal, how much
advantage is a 1KW (Tru The Hull) sounder over a similar
500 watt model?

A second question is how much will a fairing block
improve the display? The assumption is it will provide a
more stable picture at higher speeds. I boat in Alaska
where 1000 foot depths can occur as little as three
quarters of a mile from shore. Thanks - Cap'n Phil


One other thing to note here is, Frequency has far more effect
on Maximum Sounding Depth than Output Peak Pulse Power. If
your looking at only the top 100 ft, for fishing, then 200 Khz
is what you want, and you don't need more than 100 Watts PPP.
If your looking for the bottom and it is over 200 Fathoms, then
50 Khz is for you and 200-500 watts PPP, will certainly help.
If you down past 300 Fathoms, and your looking for those elusive
King Crab, the 28 Khz and 1-2K Watts, is going to be your friend.

Another note here, as well, Resolution is the Inverse of Frequency.
If your looking for fish, and want to see individual fish, like those
elusive Spring King Salmon, then 200 Khz is your friend. Otherwise,
your not going to see individual fish, with a 50 Khz or 28 Khz machine.
