Looking for some advice around the benefit of chirp as thinking of upgrading from the 3 in 1 transducer.

Generally fish in 30-50 metres but wanting something that could work as deep as 500m for hapuka and blue nose.

I have been looking at the airmar tm275lhw but wonder if this is too much for what I am fishing and if for the saving better of with a tm260, especially as more time spent closer than out deep.

If anyone running either of these or suggestion on other chirp transducer appreciated.

Thanks Riga and pretty much answered what I wanted to know as couldn't find the power of the 3 in 1. I'm really looking for hapuka or blue nose in the deep and the rest of my fishing is really for blue cod so looking for structure and reef. I just need to make a decision on price and difference it will make between the 260 or 265.

You should be able to buy an adaptor. Something like this.
