so I am in the market for a ff for my yak and i want to know what experience you guys have with either of these units on your kayak or boat. first is raymarine dragonfly 4 pro w/navionics gold; the other is lowrance elite 4 chirp w/navionics.

i previously had a lowrance elite 5 dsi/gps and it was great, however the lack of sonar made it difficult to use when anchored or slow drift.

Up until today I was dead set on the lowrance elite 4 chirp w/navionics until i did some digging into the raymarine dragonfly pro with navionics gold.

i like the raymarine screen orientation on when looking on a pc, but real world i may like the elite 4 vertical orientation more.

I plan to fish 80' or less freshwater only in my kayak so i don't need a deep sounder. i want a wide swath under slow paddle conditions. i wish i could afford a SI model but at this time it is unjustified extra expense.

I like the looks of the raymarine. But the refresh rate is slow when I looked at them at Cabela's. Lowrance has rebates that bring the price down to very comparable with the dragonfly.

Thanks for the comments and input.
I went ahead and bought the lowrance elite 4 chirp/navionics for the following reasons:

1. I have owned an elite 5 dsi/gps so I am familiar with the menu/functions of it
2. Comes with navionics maps
3. Chirp multi-range radar frequency plus Down imaging
3. $50 rebate
4. excellent waterproof rating, full submersion w/no issues

cons:
backordered
DI 3d quality lower than raymarine


The Raymarine dragonfly 4 pro

Pros:
I like the di clarity and precision, as well as the automatic chirp frequencies selected.
built in wifi feed to smartphone/handheld unit

Cons:
large ducer
priced $20 more than the elite ($70 with rebate) and I read that it would not be a good unit to submerge in water, which is an issue on a kayak due to potential flip/turtle.
It appears this unit does best between 3-5 mph which in the yak I have and my fishing style is not going to work for me. I need something that scans well at 1-3mph

the humminbird helix 5

Pros:
larger screen
good Down imaging

Cons:
Factory mapping capability does not utilize topographic contours(deal-breaker)
purchasing navionics or other mapping card puts cost of unit well above elite 4 chirp/nav or dragonfly 4 pro
apparently difficult to dial in DI


Thanks again for the input and I look forward to getting on the water in my yak and new ff once it arrives.
