Fish Finder cone angles-technical question

[Moveon]

Something to remember when talking about Cone Angles and depth finders sound wave patterns used for fishing.

There are a couple of very Knowledgeable guys that work in the fish finder dept at Bass pro in Clarksville. One is Cody and the other is on this site but can't recall his name at the moment. Maybe he will see this and chime in.

I spoke with with Cody last week about a transducer problem. He really knows the units. He has also fished with quite a few of the units.

Not saying one manu. is better than the other but I sent my unit back to Lowrance and and it took over 3 weeks to get one back. They did upgrade me to an hds unit for free so basically I got an hds 5x for $200 (price of the original unit). I have been on the phone with customer suport at Lowrance quite a bit lately and find their support to be very good.

As somebody suggested a back up unit is a real good idea.

I was inquiring about the cone angle on the newer units which is listed the same (20 degrees) as my vintage x70a but it seems to be much wider creating a much larger dead zone near the bottom when near steep banks.
