Default Furuno FCV 585 & Airmar TM270W-1-Kw Transducer

Hello Gentlemen

Anyone using this set up ?

Was intrested in using it for Swordfishing looking deep during the day about 750' through 1050' for prey and Swordfish.

From what i am reading looks like a very wide angle beam high speed etc. but really only care about the wide angle and the 1000 watts but can put the high speed to use targetting other predators near the surface.

I like this transducer for locating fish in the top 300 feet of water. I don't think it will be of much help at the depths you want to use it for. The coverage area will be too large. You want the narrow beam for that depth.

I'm waiting to hear from the manufacture but was hoping with the power 1000 watts it would work with the wide angle 750 - 1050'

Here is the E-mail i sent to Airmar.


Hello Rich

Have been looking at the Furuno 585 with your TM270W 1000 watt transducer.

I like the wide beam but have concerns.

Swordfish in our fishery Southern california tracking indicates they are 750' through 1050' during the day and at night near surface.

I am primarily intrested in looking at the scattering layer not the bottom and track the scattering layer influenced by light levels as it rises and falls every day.

This is where the swordfish are primarily at here.

Would this be the best selection ?

I usually troll at 1-2 knots not any faster.

If the wide beam will not work for my needs should i use the 660 smaller beam and save some money or is there a better unit or transducer system ?

I curently have a Raytheon V820 500 watts and Raytheon V850 600 watts and am not seeing the scattering layer as defined or as frequently as desired working the gain etc.

Hope you are abble to advise me on thease questions they have been dificult for me to understand and appriciate your advice greatly.

Any help from anyone else please chime in, thank you Keith


EDIT Ok guys found this and looks like it answers my questions and will wait for Airmar to respond, hopefully in detail but still would like to hear from anyone who has experience especially tracking the scattering layer accurately using all the feature etc.

Have extensively tried using the 600 watt sonar with a supposed 5000' range with out success using all the feature zoom etc.

Most of my targeted predators to date have been relatively shallow water being abble to primarily use visual indicators of their presence day and night gyros & bioluminescence but sword fishing in our fishery is causing me to expand my effort.

Here is the reply from Airmar



Hello Keith,

The SS270W is best for depth up to 200-300 feet. Although the SS270W depth range is 330-600 ft on 200kHz and 1350-2000 ft on 50kHz, you have to remember that it's a 25 beam and the deeper you go larger your viewable diameter will be. Some examples of the viewable diameter are below. I understand a wide beam is desirable for game fishing.

Viewable diameter based on depth.

Depth Viewable diameter
50 ft 22 ft
100 ft 44 ft
200 ft 89 ft
500 ft 222 ft
1000 ft 443 ft


Here is my reply


Thank you for getting back to me Paul

Since i am intrested in primarily looking between 750' through 1050' in water
that is much deeper than 750' through 1050' should i be looking on the 50 or 200
split screen or go to a single screen and zoom in to 750-1050' ?

Thanks Keith

Hello guys I have a furuno fcv-585 model with the tm270w 1 kw transducer and I have a problem with the 50khz frequency. The thing is when I stop the boat I can read perfectly clear evthg on the screen on the 50khz but as soon as I start trolling the screen gets filled with noise i.e.: red clusters. For the noise to go I adjust the gain to 2 which is very low. Everything above 2 the screen becomes all red. Where as the 200 kHz works perfectly fine while cruising. Any idea what's wrong?

Hi new to this Club. Have a few questions.
1) What size reel and what lb test line should be used for an average 500lb Marlin?
2) how much braided line should be used?
3) how much Mono line should be used before the braided?
4) how much wire leader after the Mono?
