Ok,now that 2 pro staffers are on board can we make a clarification?I am looking into upgrading to a HD unit and have been to BPS twice within the last week.Both times I start asking ?'s about Lowrance units the salesman claim not to know as much about lwrce. and steer me to the HB units.Also,they stated that HB sued Lwrnce. and won.Furthermore,they say parts on the new LWRNCE. units may be ?.Thanks.
