Nelly, thanks for the quick response. I agree, the high chirp is great. It is really nice to be able to see if the "blobs" on the bottom are fish or just garbage. I would love to upgrade the transducer to the tm150m but as I said I don't want to lose the mapping abilities provide by insight. According to insight's user guide it states "200kHz or high chirp mandatory". According to Airmar's spec sheet the tm150m "Covers the medium frequency range—CHIRPs from 95-155kHz to provide 60 kHz of total bandwidth from one transducer". I would hate to spend the $300 and then find out it won't work and of course the insight customer support is unavailable. Hopefully, someone, somewhere will have upgraded and can confirm one way or the other. Again thanks for the reply and the website, I enjoy it.
