TZ Navigator v3 Video Sneak Peek

April 15, 2016May 17, 2016TIMEZEROLeave a comment

TZ Navigator is now officially set for release: May 19th, 2016.

In this video you will see all the new features in action:

Click to watch the video

New User Interface

Our redesigned user interface will make your life much easier when it comes to route planning and all the features you are familiar with (Tides, Currents, Weather Forecast, etc.). All the concepts which made TIMEZERO a huge success (Tool Bar, Layers and Navdata) are now included in an enhanced User Interface fully adapted to be used on touch screens!

Security Cone

The new Security Cone is a feature in adherence with the official rules of the IMO. It uses the data in vector charts or the 3D data within the charts to detect shallow areas and isolated dangers. If an obstacle is detected inside this cone in front of the boat’s trajectory, an anti-grounding alarm will automatically be triggered.

Secure Route Planning

Route Planning is of the utmost importance for every boater. Our new technology assures the security of a route upon creation. Through color codes (green/red) it is instantaneously possible to know if the depth is sufficient for the safe passing of your boat.

And more!

Note: The release of TZ Navigator will mean that we will stop supporting all TIMEZERO v1.9.8 and below. We will continue however to support v2 on all compatible operating systems until the end of 2016 (Windows XP, Windows 7 and Windows 8.1).

May 8, 2015July 17, 2017TIMEZEROLeave a comment

We are very excited to announce the release of a new version of the MaxSea TimeZero App for iPad: v2.0.0! This updated version includes lots of useful new features, designed to make boating easier, safer and more enjoyable.

Here is a summary of the most important new features:

Free chart updates

Whatever chart area(s) you previously owned will be updated once you install V2 of the MaxSea TimeZero App.

AIS compatibility

The MaxSea TimeZero App can now integrate AIS data, as long as you add on the “AIS Module” which is an In-App purchase. This module allows you to connect any NMEA 0183 AIS receiver through the Wireless Network, and display AIS targets on the App’s charts.

Detailed AIS target information is available by touching any target on your screen. This displays Name, MMSI, CPA, TCPA, Vessel Type, Size, etc.

AIS Module Price: 8,99€

External instrument connections (NMEA)

Now it is possible to use external instruments that have been connected to a NMEA 0183 WiFi multiplexer through the Wireless Network. The Maxsea TimeZero App can now display additional data such as Depth, Heading, Sea Surface Temperature and use a dedicated external GPS.

Share feature

The Maxsea TimeZero App for iPad has launched a new (Beta) service that lets users share their position with friends and in turn, see their friends’ positions on their chart.
Positions are only shared after an invitation has been sent and accepted. You can manage your friends directly from the app or from the dedicated website.

Your position can be viewed on devices other than an iPad. In this case, the friend must create a My TimeZero account. The user then shares their position with this account, which can be viewed as a regular web page.

FURUNO DRS4W Radar compatibility

Now you can integrate the MaxSea TimeZero App with the FURUNO 1st Watch Radar! To do so, the Radar Module must be added as an In-App purchase. This module allows you to connect the FURUNO 1st Watch Wireless Radar to the MaxSea App.

You can then overlay the radar image across the navigation chart in the MaxSea TimeZero App, ensuring heightened security onboard.

MaxSea at IceFish – the Icelandic Commercial Fishing Show

October 2, 2014TIMEZEROLeave a comment

Last week, Regional Sales Manager Thibault Hua represented MaxSea at the IceFish exhibition which took place in Reykjavik. IceFish is the must-visit event of the commercial fishing industry. Here he tells us how it went.

MaxSea products were displayed at the stand of Iceland’s Furuno distributor Brimrún. Special emphasis was placed on our PC-radar and fishing-PC sounder solutions with Furuno sensor integration. The new WASSP interface was also very successful because of the increase in productivity and time it represents for bottom mapping tasks.

The Classroom Training

The Group Sales Manager at MaxSea, Frédéric Algalarrondo gave an introductory speech, welcoming all the particpants to Barcelona, and explained the schedule of the week.

Iker Pryszo then spent one day giving a technical training session on TimeZero Coastal Monitoring, a turnkey surveillance system that can be configured for a range of commercial applications, such as for ports, harbors or oil rigs.

On the second day, Iker presented MaxSea TimeZero PLOT, which is designed for commercial fishing and can now be integrated with WASSP multi-beam sounders, resulting in an extremely effective and powerful fishing aid. The MaxSea WASSP Module is required for this software-hardware integration.

The third day of classroom training was a techical training on the WASSP multi-beam sounders, presented by Phil Seyb and Nick Fogarty.

The Welcome Dinner

After the first day of training, all the seminar attendees plus the MaxSea Naval staff enjoyed a dinner together. Some people stayed out later than they should have, but the details of this night are highly confidential and cannot be publicly disclosed…
