627 + 1kw is it possible

 Gday crew,


I'm looking at taking the inlaws boat north in May.


I want to replace their shitty old garmin sounder with the 587/588 plus 1kw tranny TM260.


I'm wondering if i can buy the TM 260 and run my head unit FCV627 on that?


I'll upgrade their head unit to the 588 later but for now i was hoping to be a tight arse and not spend the funds.


I've been google searching and most say you can run a 1kw tranny through a 600w head unit but i just wanted opinions here especially if guys are doing or have done and what results they were getting?

Yes you can. Wont get the extra power but you will get more detail as the transducer is far more sensitive

 What Tim said...the bigger head will receive return echos better, but you wont send the pulses with any additional power (only 600W).

 Talk to rhys from Taylor's you may be able to get a matching box to run the transducer. I know guys use the 585/588 with a matching box and can run 2kw 50khz and 2kw 200khz tranies. Yes the head unit only puts out 1kw but I was told the matching box dose the rest


Any one free to help me pull my drum lines tomorrow?

Matching Box

Matching box wont help in this regard.
they are used to connect non diplexed commercial transducers to a head unit like the 628 or 588.
You could use these on one of these units but considering you are trying to do this with a budget I would theink the TM260 would be your most efficient option.

If money isn't an option you could try and fit a 2kw 50 kHz to the boat on a custom bracket. The bracket and matching box without transducer will cost you more than the TM260 though.

 I've got a m260 if you're interested. Been sitting in my cupboard for a while now and no plans on using it soon.
