1) There was a warning in the clam shell package for the EC-W10 stating not to power up the unit using the extension without a transducer attached. Would doing this damage the head unit or just "confuse it"?
2) I recently placed an order for a GRHA GPS receiver from J & H Products. I received an email this morning from John saying that the GRHA are on backorder and that he is "being told today that Humminbird discontinued them". He has since removed them from his site. Can anyone confirm or deny that Humminbird has discontinued the GRHA (and if so - why)?
Thanks,
Darrell
