I am a college student from the UK. I'm currently in the process of designing a kayak navigation system.

The problem with a navigation system is power. If on a multiday trip there will be no power though some take solar cells if they really insist on running phones, cameras etc.
A paper map weighs nothing. It doesn't fail due to batteries going flat. They are easy to read and can cover a far greater area if spread over the fore-deck. Easier to see than a small screen in bright sunlight.
Paper can be more up-to-date than an electronic systems. This mainly applies to vehicles where you'd be lucky to have anything better than 5 years old (Subaru is an example - rubbish navigation system).
Far more useful is a VHF radio for weather reports and emergencies.
I don't know why one would go for a navigation-only device when phones do it so well and can be used for emergency communication as well.

Lithium batteries used to be high hazard in salt water, I haven't done electrical/electronic engineering for 11 years but back then I found it marvelous how kayakers would place potential bombs near their own seat. obtenir prêt Potentially about 2 years from owning electronics, I would prefer internal or flip out to provide 12 hrs use housed inside a lightweight sturdy waterproof mountable case. Small lithium with recharge circuit would be ideal to open up dry storage and recharge from a secure 12 volt bank. Eg USB without time constraints.
Wish you well.

I use both a fish finder and a GPS (both Garmins). The GPS is a Garmin etrex - i prefer the light weight as I also use it walking. However for purely kayaking weight is of minimal practical consequence - although lighter is always nicer if all else is equal. I also like having the GPS separate to the fishfinder for redundancy purposes (i.e. fish finder is more likely to fail).
The eTrex gets up to 3 days on a pair of rechargeable AA batteries - it is simple to carry some extras to swap over in the evening for the rest of the trip. Never kayak camped at a campsite with any form of power. I wouldn't ever use my phone for navigation - uses too much power, needs a good waterproof case, hard to recharge plus I want it safe under the hull in case I need it at camp for an emergency (though many of the camps up here have no reception).
Good to have navigation on the kayak as it makes for efficient routes on distance paddles and great when landmarks are all covered up by rain.
Fish finder is much less value than a navigation device for fishing, although a fish finder is nice. One thing I have really come to enjoy on the fish finder is watching the 'terrain' that I am passing over out on the ocean.
I think you will find the almost all sea kayakers regularly do full days on the water - so 8-12 hr operating time at a minimum is required (and more is better).
Good luck with the research!
