Simrad gave us a new chirp black box sounder (S5100) to replace the BSM 3 chirp box. We had placed multiple calls to their tech support complaining about performance, they had already changed out the BSM2 for a BSM3 previously and sent a tech twice. Anyway my phone rings 2 months ago with a call from New Zealand, a Simrad VP calling to ask some questions including if we would like a free new chirp box, no shipping, no other BS. Now I'm really mad because we now know what we've not been able to see swimming under the boat, think that's pretty good customer service.
