FCV585 and M260 depth


I have an FCV585 with an M260 (IkW in hull) transducer.

On the weekend i was out in around 200m and was struggling to read bottom at 6 knots.

I had TVG set to High, using 50kHz....I thought i would read better with this setup. Any suggestions? Shallow water performance has been awesome.

Anyone have a similar setup and what sort of performance do you get in deeper water?

 I'm running a 587 with ss264. Runs out of legs around 430m


Does anyone know where the love of god goes, when the waves turn the minutes to hours?

Same set up

i had the same set up and was not getting much better maybe 250m tried everything. Researched everywhere to do better mixed a few things up changed a few things with no better results. You get mixed reports some go great and get good depths then some like ours don't do what I thought would be better than 200's.

Dont expect anything more than 6 knots. Even those with commercial units on small boats cant get much more.
You should bet way more than 200m. You should get over 500m with full detail while drifting but moving can be variable for a number of reasons

Not true?

Whats not true? That you can get 500m? Or that speed can affect it?
It is only 1 kw and you wont get a lot of speed out of it.
And water conditions would be one of the variables I mentioned. As well as transducer type, fit up, settings - it goes on and on

Even with a 295 and 2kw units whicj I now have you cant go real fast.
Peoples expectations of what they want and reality generally dont meet out deep.
I have had both and it is amazing what you can find with the 585-588 type units.

From my experience, if you

From my experience, if you put the time in and don't dick around with transducers and half arsed setups. A properly set up tranny and you should be able to sit on 9-11 knots in all fishable conditions. Not much it sounds but you sit on 6 knots all day looking for fish compared to 10-11 it makes for a shit time. I wouldn't want to be restricted to looking for fish if it was a bit sloppy

Bsir id look at other options in mounting the tranny

i think it would be really interesting to compare the tranny transom mounted compared to in hull. I do like the in hull tranny because I do read really good in 100m, even at 30 knots it's still nice and clear. I've never had that much clarity from transom mount.

Next install would probably be through hull with an ss164 or 264, but that's a bit expensive for right now. Maybe another year down track I can upgrade the whole lot.

How much fibreglass are you beaming through. Most guys I know running in hull transducers are running 2kw

Not sure

its a cruise craft hull and came with a built in section for mounting an m260. Not sure of the thickness though, i would guess it is the same as the rest of the hull, and I don't know what that is.

Tuning guide

Have you run through the tuning guide exactly?

Good point

Sun, 2017-04-16 02:33

I have used this guide before but only in around 50m. I did adjust TVG and clutter but next time I will follow the guide and see if it can get any better.

if not....it might be back to the drawing board.

Mine worked well

 I took my boat out wide last week with a 588 with a 1kw shoot thru tranny and read bottom nicely in 250-350 easy. Still read bottom in 500 metres but started to struggle a bit in that depth. Over all I was pretty impressed with it
