Humminbird-HELP

[mobassin]

got a 345c for xmas and never used 1 before. the manual is pretty vague. I've had it out on the water a couple times. I set it on 9 chart speed and 70-80% sensitivity. I'm getting good pictures I think of bottom and structure but no arches yet and I also had what looks like odd shaped ponds blue in the center and a thin yellow outline around it with a little red in it sometimes. Could someone tell me what I' seeing? Would love to find some dvd's to rent somewhere. Can't afford to buy any as I've been off work all winter. Any advice will help.

I'm a Lowrance guy, so I'm not the best qualified to help you on this.  But I'd say your sensitivity and chart speed are right for most conditions.  I'm not sure what the blobs are that you're seeing, though.  What depth are these at?  Can you record a screenshot and post it here?

I was in 9'-11' of water and they were showing up at around 5-8' deep. I've asked around and most of the guys told me after I set every thing up like I want on manual to put it on auto. It doesn't have a auto button so I went back to the book and it doesn't show any info on it in there. I'm wondering if maybe I should put back in normal mode. I left it set in advanced mode to set everything up. Thanks for the responce. I guess I'll keep hounding hum....till I get a responce.
