dragonfly 5 series questions please

mtnbowhunter,

Q1. Is there any difference other than software updates on early issue dragonfly 5 dvs versus the 2017 models / version??
A1. No.

Q2. Does varying screen brightness have much effect in power consumption??
A2. The display's backlighting is responsible for approximately 50% of its power consumption. Accordingly, adjustments to its backlighting level will affect its power consumption. Raymarine has only produced power consumption specifications for the full brightness backlighting level.

Q3. How about power usage when running dual screen sonar and down vision versus single screen?
A3. See the response to Q2 ... the remaining percentage of power consumption reflects both sonar features being simultaneously in use. Raymarine has not specified power consumption for DownVision alone or for CHIRP (conical) Sonar alone.
