Curious what you get for battery life when using a Echomap+ 7 or 9 inch units? What battery are you running? Would a single Dakota Lithium be enough or would you have to run 2 in tandem?
Would be nice to get the following info for a good comparison:
Echomap+ 7:
1) Garmin Battery runtime = about 7 hours
2) Single Dakota Lithium Battery runtime = 10-11 hours
3) Tandem Dakota Lithium Batteries runtime = in theory double. The only individuals that are running duals are the livescope guys
Echomap 9SV:
1) Garmin Battery runtime =
2) Single Dakota Lithium Battery runtime = ?
3) Tandem Dakota Lithium Batteries runtime = ?
– these numbers do not vary by much. the difference between the 7 and 9 while running the same settings is around .1-.2aH
I am running a 7 plus unit on a shuttle and I have found 12 hours of run time is very doable. I fished outside last weekend for 7 hours…screen brightness at 60%. Left the lake with a 62% reading on the shuttle. Those who are running one dakota are reporting right around 10 hours of run time.
There is a very big consensus to get rid of the SLA that comes with the bundle as it is garbage in colder weather and is extremely heavy.
If you want a ton of information on this I recommend joining the garmin panoptix ice fishing facebook page. This topic is discussed often and at length.
