Tuesday Tech Tip: Sounder Basics

Today’s Tuesday Tech Tip: Sounder Basics

This is a long one, where we go into detail about interpreting the sonar screen, using functions such as gain, choosing a frequency, and the benefits of down-scanning & side-scanning sonar.

Tuesday Tech Tip: Proper Transducer Placement

Tuesday’s Tech Tip: Transom Transducer Placement.

Wherein we look at some examples of both good and bad transducer installs, and what to look out for to get the most out of your transducer.

Tuesday Tech Tip: Grounding your unit

Tech Tip Tuesday: If you have a Furuno FCV fishfinder and are fishing in reasonably deep water, make sure you earth out the sounder correctly – it can have a marked difference to the sounder performance! On the FCV62* and FCV58* units, there is a machine screw which is the earthing point on the back of the unit, just below the power connector.

New Garmin inReach Satellite Messengers

These cool new satellite messengers from Garmin use the Iridium Satellite network to keep you in contact with family and loved ones whilst you’re out of normal cell coverage.

The two models available share the exact same satellite messaging functionality. However the main difference between the two models is the added topographic mapping capability of the inReach Explorer+. While the inReach SE+ is GPS enabled and allows you to mark waypoints and leave trails on a grid system, the Explorer+ model allows you to use preloaded topographic charts and use waypoint routing.

Auckland on Water Boat Show 2016

We recently went and visited some of our suppliers at the Auckland On Water Boat Show, to find out about what’s new and what’s up and coming in the world of marine electronics. Watch the video below to see the highlights from Garmin, Furuno, Fusion and Lowrance.

QuickDraw Contours: Setting Install Depth and Tide Offsets (Using Panoptix)

Garmin QuickDraw Contours + Panoptix

We recently had the chance to get out on the water and do some decent testing with the QuickDraw software and a Garmin Panoptix transducer. This video also covers some aspects of set up that you’ll need to do before creating your own charts, such as setting install depth and tide offsets.

Needless to say we are blown away with how well these two technologies work together and look forward having more of a play.

Easter hours

Happy Easter everyone! We will be closed for the whole weekend but will be back and rearing to go on Tuesday!

Quickdraw Contours – Update Now Available!

Great news for Garmin users! The much anticipated Quickdraw Contours update from Garmin is finally here.

We had the chance to test the update before release, and we have to say, this new feature is amazing.

Quickdraw Contours is a free update which allows you create your own charts of the sea or lake floor using your Garmin sounder and transducer, which updates live while you fish.

This is especially useful for lake fishers as it allows you to map out your own favourite fishing spots where other maps may not exist. Mapping out your own fishing spots helps you to get greater detail and accuracy than what you get with traditional charts. That means you can easily identify rocky areas or dropoffs where fish might like to hang out.

One of the biggest bonuses of this update is the fact that all the processing of data is done in your sounder unit on-the-fly, there’s no need for extra software or computers to process your maps and you don’t need to be a techincal wizard to use it, meaning you get more time on the water doing what you love – fishing.

Watch the video below to see the Quickdraw software in use

Quickdraw is suitable for use with any Garmin Panoptix™ transducer, any HD-ID™ sonar, any CHIRP-enabled, Garmin DownVü™ transducer or NMEA 2000®-compatible depth transducer.

This update works with any of the following transducers: Garmin Panoptix, HD-ID sonar, any CHIRP, Garmin DownVü or NMEA 2000 depth transducers.

If you’re not sure whether your Garmin sounder is compatible with this update, please see below for our list of Garmin products we know it works with:

GPSMAP 7407, 7408, 7410, 7412, 7416, 751xs, 820xs, 1020xs, 557xs, 8012.

echoMAP 45dv, 55dv, 75dv, 75sv, 95sv.

Simon Smith “Got these shots out from Tairua yesterday. We spotted the Tuna on the surface and got a triple hook up on Big eye but lost one. Went back on the sounder and saw the amazing sign then marked it and went back 200m to it and got back on the Tuna. Garmin 7410 with GT51. We have the TM265 but find we get much more detail just watching the top 150m with the GT51. Fish went 43kg and 35kg”

Furuno Gets Bathy Charts

Furuno’s GP1870F and GP1670F plotter/sounder combos are now shipping with the C-Map 4-D Bathymetric chart. These charts are not based on the older bathy information which other bathy charts are based on, but instead are based on a much more recent Navy survey. The improvement in detail and accuracy is noticable.

To celebrate, until 8th Jan 2016 special pricing applies to these models including a Transom Transducer and NZ Chart with Bathy Data.
GP1870F-DT-NZ   $1099

VHF Frequencies Changing

Recently Radio Spectrum Management announced the Marine VHF channels will be changing at the end of 2016 . So what does it mean for you and your existing VHF? So far we don’t have all the information, but here is an overview of how we expect your radio to perform after the change:

Existing Channels 1-18 , 27-77:

NO CHANGE – You will be able to use your radio as you have been for any of these channels


Existing Channels 20-23:

You will still be able to recieve Now Casting weather by tuning to the correct frequency – New channels which start with “20”, such as 2019 or 2079, can be recieved by tuning to old channels without the 20 – so in my example channel 19 or 79. Note your local weather channel may change, for instance Hokianga currently transmits on CH22 will transmit on 2079.


New Channels 1019,1020,1078, 1079

You will be able to transmit on these frequencies by selecting the channel without the “10”, But you won’t be able to recieve on these frequencies.


All other channels:

Will now be used for data purposes, you will still be able to select these frequencies but you should not transmit as you may be interupting data transmissions.

If you do have any more information, or would like to ask us some questions, please get in touch!

Prices keep falling

The managers at Furuno, Garmin and Lowrance mustn’t be checking the exchange rate cause they keep on dropping the prices! Its a great time to take advantage of the fantastic prices before they figure out they’re shafting themselves.

GARMIN 2015 new releases – CHIRP, CHIRP, CHIRP

This time of year is always exciting – the weather’s good, game fish abound and the tech companies are releasing new product lines. WE LOVE IT !We have just had a sneak preview of Garmin’s new plotter/sounder combo’s, and as usual we’re keen to get out and test them. The buzz-words at the moment are CHIRP and SIDESCAN.Back in 2012, we predicted a CHIRP revolution, and that is being proven the case, with all the major companies getting into it. Now Garmin has also built SIDEVU (sidescan) technology into the GPSmap range, so no need for a separate black box, and the new transducers will do the lot: Traditional/DownVu/SideVu and Chirp – all in one. Exciting stuff, and the prices will be SHARP!Watch this space – we will be reporting on the new models soon.

Boat Expo 2014

Its that time again! Tauranga Boat Expo Time! Come and see us for a fantastic range of awesome specials!

Awesome Prize!

How would you like to win an AWESOME Garmin GPSMAP 1020xs? There’s one up for grabs at the upcoming Top Catch Heavy Metal Jigging Tournament, November 15-`16, at the Tauranga Sport Fishing Club (Inc.). Its gonna be great!


Lowrance releases colour fishfinder for under $200

Lowrance today announced the elite 3x, which is a 3.5 inch colour 180W sounder. Fairly standard so far, in fact it is exactly the same as the lowrance elite 4x, the noticable difference? the price – these units have a recommended retail price of less than $200. Crazy pricing!


NMEA2000. Simple.

NMEA2000 is a common language which is used by a number of manufacturers to communicate various bits of data between units. You can do some amazing things with NMEA2000, and the best part is that putting together a system is as easy as playing with lego.

What is NMEA2000?

NMEA2000 is the marine version of CANBUS, the same system which is used in your car to control things like air-conditioning or the GPS. In marine format, it usually has standardised connectors, and generally uses standard sentences, allowing you to connect different brand name sensors and displays. For most of what we do, the display used is the boats chartplotter, which is well set up to co ordinate and display complex information, and the sensors are GPS, wind, tanks and engine information.

Why use NMEA2000?

Because NMEA2000 is a standardised system, expansion or changing the system is extremely easy. For example, if you have a wind sensor on the top of the mast with a display in the cockpit, previously if someone damaged the display, and the unit was a couple of years old, you would usually need to swap both the display and wind vane, including re running the cable down the mast. With a NMEA2000 system, you can swap or change either end, or add another display elsewhere if you wished, or add another sensor (eg depth or tank level). You could add a transmitter to receive the information on a watch, or send it over a cellular connection to a remote computer. The system is much more flexible, and will help future proof your installation.
