Anyone know if we need to buy something extra like a chirp box or is it built in
The CHIRP sounder (transmitter) is built in ...
It will be transmitting the CHIRP sweep frequency thru the stock xducer that comes with each specific model (2d model, DI model, or SI model) ..
There is talk of an optional xducer but we have no specs for it yet ...
-----
We also have no news of other new products yet ... (none of us here are employees of HB to be privy of this info) ...
