Navionics Boating gives me river nav coverage .....

[Refueler]

Where I live - alongside River Venta in Latvia - navigation coverage is limited for me to my own created charts on a Lowrance Globalmap plotter or the best - is Navionics Boating app on Android.

But because I have a number of boats and at present all 3 installs are used ... I have to carry tablet / phone from boat to boat ...

I want to mount a tablet permanent to a couple of boats that I use on the river ... the question being how to have nav displayed without paying out more subscriptions ...

Its winter and I'm waiting arrival of new tablets .... so the idea is to come up with a solution.

Going through my mind is 'mirroring' my phone Navioncs to the tablet of whatever boat I am on .. giving me 'in-hand' control on the phone ...

My concern is that I use mirroring at times for other to large TV's etc .. but find it a bit unrelaible at times ...

I realise that initially it appears that I will be doing roughly what I do now ... carrying tablet / phone boat to boat ... but it allows me to not have to ,oumt the phone etc.

Anyone else doing similar ?

Not sure if this helps but: Navionics will allow you to be logged in on two devices simultaneously. If you log in on the third it will ask you which device to remove (as I recall if that device has no internet connection it will continue to work until you need to so something that requires a connection).

Alternatively is there good 4G connection in the area? Not sure if Orca's maps cover your area, but its free to see. If you don't need autopilot/instrument integration and sail in areas with good phone signal its a nice package.

Oh and I agree mirroring is a bit flakey. Is it bi-directional? I've never mirrored to a touchscreen device before - but if its just a repeater not being able to zoom would be annoying.

If you have a scanned copy of a paper map or screenshot using Google Earth or Open Street Map etc, you can upload your own map to Memory Map and calibrate it. I did this a few years ago for a region of Namibia I was going to visit.

2x simul .. but only allows 3 installs to be current .... that's where the limit comes ....

As far As I know - Nav Boating is only plotting that covers all the river to the end of navigable ... other than my own maps created for the Lowrance.

I used various sources of maps to create my own vector maps for the river and they display on my Lowrance .... but the limitation was I did not add in the depth contours at the time and since getting Nav Boating - not really needed to go back ...

My posting is about the slaving of Nav boating to a repeat display ... there's no need for repeater to control the app .. that is done at source (phone) ....

What I find strange is that Navionics SD card for my main plotter does not cover the river upstreamn of the harbour, there is no card coverage .. in fact its only Nav Boating that does.

Not sure I'd rely on the depth information on a Navionics chart, especially in a river. Some of the source material (eg depths in the ocean around the UK) were last done 200 years ago with a lead line if you look at the source areas on Admiralty charts.

Can your device map the depths as you travel around? Even a single contour would be useful.

The river depths are actually very good .... locals use it for fishing ... I know of deep holes in the river - Nav Boating shows them spot on ..

This 2 device limit has me actively looking at alternatives. Garmin ensh*tificstion,undermining redundancy. If it was limited to 5 devices I would be less cross. Two is just unsafe. That an no ,onger being able to plan routes on my laptop and then save to the cloud.

That said, it is a great app. The tidal data is very handy.

I tried Aquamaps last season and liked it. But no tidal data for UK users. They tell me it has s coming. Opencpn is also of interest.

The mirroring thing is a nice idea but what if the phone goes down. I guess you would have a back up tablet but would that mirror? I find mirroring quite glitchy at the best of times so I'm wary.

The best solution is for us to all e mail Garmin demanding more than two devices access. If they choose not to listen, a competitor will eventually win me over.

I’m sure they’ll reply pointing out you can have as many devices as you want - if you pay for them!

If the phone goes down and I lose mirroring to the tablet ... that's no reall hassle as I am only loking at this for the river ....

I know the river like back of my hand ... but its nice to have speed / eta / reference as I go along ... a good example is when I had last guest boating trip with the MoBo ... I was able to get back home because of time / distance / speed known via Nav Boating when the port fuel tank ran dry ... silly error on my part .... but I knew that stbd tank could just get me back based on info up to that moment.

Anyway ... I don't think Garmin are interested to open up the app more ... they are a business and money is the base line.

I will be trying out various 'solutions' while winter has its hold on us ... and will post the results as I do them.
