My old basic depth sounder has given up so looking for a replacement.

Huge choice out there and its a question of how much to spend - what do I need. I'm up to, as a minimum, a fish finder/GPS unit at about $500. The question is whether to outlay an extra $300 odd for one with a chart plotter?

I mainly fish in familiar waters, ie Firth of Thames and Tauranga. Also sometimes Rotorua lakes - but I understand there are very limited charts for the latter.

Any thoughts?

These days having a chart plotter is so much better with what you can view, eg your trail of where you are and where you have been, in case its dark or foggy and you then can come home following the trail you came out on. Thus, a great navigation tool.

The CP will have a modern map of the area which may show reefs and interest for fishing/prospecting... new CP will have bathymetric mapping as well for more depth contours, very useful when looking for new ground.
And of course you can mark and plot all your areas of interest and your own spot x's for future reference.

If you are only fishing in close and not over 150m then a standard 200Khz model of sounder/fish finder will suffice with standard transducer, but if you are a tweaker and want to examine the fish/bait and contacts mid water and good definition of structure on the bottom, then ask for the narrow beam high performance transducer to match the sounder/FF.

Also with the CP... the best bit is cruising over and area and seeing great fish sign and creating a waypoint or mark and then drifting back over that or the rock you have found.Big smile

Very well worth the extra funds mate.Thumbs Up

Definitely fork out extra for a chartplotter mate. All the reasons listed above are easily worth the additional costs

The GPS chart plotter any day. If I had to choose one to break down it would be the depth sounder not my fishing marks.

I run a lowrance 7" HDI .. a budget units but bit over your pocket depth.
I use this for sounder only.

 I still have my old 7" huminbird.. transducer removed, and as a general gps...and yes it is just general.

I have a $150 levato 7" android tab with fully updated, subscribed navionics (about $35/yr)  for my main gps  to drop me right on that gutter in a reef, or follow a route or track out or back in the bar.

I also have navionics on my android phone and a spare  10" tab. Latter is just a spare.
 They all sync, talk to each other...all for the 1 $35/yr subscription.

Like others.. the gps is my go to.. once you have your spots marked over different seasons /tides its more a matter of dropping lines there, fish markings or not,  rather than using the sounder.
 Sounder and side scan for getting down creeks in 400mm water to the river.. staying in channels crossing bars, finding new foul, new spots.

 The link below is good value for a 7"unit. $390, no charts but GPS for trails. May suit your needs.

Not saying its a big issue but sometimes handy to follow your trail in reverse heading home, when visibility is poor.

Which can be done just as well a a tablet with Navionics app loaded.

What marinised tablet have you found at a reasonable price, Steps? Anything cheaper than a chart plotter?

Spend the extra 250-300 on a 8 inch Tablet with built in GPS to use as a plotter, that way you can see your sounder on a descent sized screen and your plotter on one too.

Thumbs Up yep and it will be about the cost of actually buying the maps which is on top of the cost of the sounder Wink
 The sounder only comes with a very very basic map

I started with my little hauwai smart phone for a while.. then a 7" cheap 2nd hand , android 4 from memory tablet with gps.
 I have updated to a sale price obsolete adriod 5 or 6 levato 10" android 5 or 6 a couple yrs back but still use the old Huawai
 Marinised.. on fine days just have it in a holder on the dash rail... wet or going over the bars it goes in a ziplock

 I dont use the obsolete 'new ' 10" cause it is by the spa pool to watch the news etc...
 It is loaded with navionics, as is my phone, and the sounder with a very basic version I got 2nd  hand but cant rem the last time put the gps up on the sounder., and they all sync up tracks, routes, markers and my fishing logs very nicely.
 Even the old tablets repeatedly drop me with in at least 2 to 3 m of where I want to be on very cloudy days or in the back of a island cliffs.

your budget allows 8 hundy, you will get a nice 7 inch unit for that

you definitely want gps tracking

hook the fish, mark it, track back to the hook up, then catch his mates
a good option..... allows navionics card or similar... its an added cost for this feature, certainly future proofs this setup, to me, better than an additional mobile device that can do similar cheaper

if you fish the Rotorua Lakes and want reasonably detailed charts of the bottom contours - C Map genesis social map will provide most of the detail you need https://www.genesismaps.com/SocialMap" rel="nofollow -

Hey mate, I have a Lowrance HDS7 Gen2 chartplotter/sounder incl transducer you can have for $250 if you want it.

I'm in Rotorua and fish the lakes a lot. I can show you how to get all the bathymetric charts for all the lakes free from Insight Genesis.

Vaguely related question..... I’ve got an HDS 9 and I’ve been meaning to sort out Insight Genesis for a while. Does it add much in NZ? It’s a crowd sourced map update right? Do enough kiwis contribute to make it worthwhile?

And also.... I’ve always been told not to run a sounder out of the water too long to avoid damaging (overheating?) it. Do you unplug the transducer if you’re running the unit out of the water for a while?

Cheers

depends who you talk to.... some say its an old wives tale
its the transducer that would heat up killing it
some of the newer ff/gps units you can select to turn the transducer off

I have a humminbird helix on my kayak, bought the spot x book, enter the gps marks, sometimes fluffing around on it for an hour or more.... still going ok

[Yes leaving transducer out of water and running can damage the transducer. Garmin units after turning on push On/Off button and a new menu pops up. Disable transducer. Turn off very simple to turn off and on. Transducers are not cheap why take the chance]

Smaller transducers, probably OK for a while.

Big suckers like the 1kw+ models... they come with a tag saying "do not operate this out of water, it will damage it" or words to that effect.

There was a threa not long ago discussing transducers out of the water...
 Older models, few yrs back plus now, get hot and break down /fail. They , like modern head units can shut off the transducer.
My old huminbird I only use for gps, althu has no transducer , is turned off.

 Apparently as mentioned here Garmin and I think most brands automatically shut it off  now.

I think it is good practice to simply save your days track (if wish to) close down the units along with killing and tilting the engine up, close the clears windscreen etc, when stopped at the ramp, before getting the trailer.

Any Lowrance owners with feedback on Insight Genesis? Does it add any detail to NZ charts?

This is Lake Rotoiti showing my drift trails - very detailed and this is the simple social map anyone can down load from insight genesis social map web page - saved to sd card - i have hds7 as chart plotter only
