If you are interested at all in the Garmin, then Rickie gave you the best advice possible. Lowrance used to sell ducers separate, too. I have Garmin 93 with the GT ducer. Quite happy all the way around. I do think HB, compared to Garmin, shoots SV more laterally. However, I have two friends with HB and their pics are not close to mine. BUT I am 100% sure that is in the operation. I would not be scared from Garmin, I would just do as Rickie said. Their warranty and after warranty repair is the best out there. Raymarine has some great pics, so do Low and HB. Get one with the features you want, the price you are comfy with, ease of operation and don't look back. It isn't about a favorite brand, it's about what works for you.
