PawTrax has been supplying GPS pet tracking collars since 2009 and has now launched version 4 of its Halo GPS cat collar.

Slightly wider than previous versions, but a full 20mm shorter, the Halo V4 is still low profile at just 8mm at its thickest point.

Weighing in at just over 22g and ergonomically curved it is comfortable for most cats to wear.

The new version 4 now has the added features of an on/off button and two status lights and more sensitive antennas, for quick and accurate responses.

The Halo is fitted with a secure and safe collar.

Using GPS and GSM/GPRS the cats location can either be sent to the owners mobile phone, on demand, as a Google map link or tracked in real-time via the optional web based PawTrax mapping platform, which can be viewed on any web enabled device.

This platform can also display historic tracks either as points, a snail-trail route or as ‘Hot Spots’ showing the cats favourite haunts.

Owners can watch a paw print move around the map, at a selected interval, keeping tabs on their cat.

Using a PAYG sim there are no costly monthly subscriptions. A Global Roaming sim option is available which ensures the Halo always connects to the strongest 2g signal.

The roaming sim allows the device to be used outside of the UK and PawTrax are currently tracking cats in many countries including Sweden, Netherlands, Belgium, Norway, Iceland and Poland

The Halo lasts up to 6 days in Locate mode before it needs recharging (it will send a text message when battery is low). Operation time in tracking mode varies depending on the selected update interval. With updates every 10 minutes it’s about 36 - 48 hours. Tracking can be turned on and off at anytime simply by sending the Halo a text message.

Managing director, Peter Callaway, says: "Our new Halo V4 has been so successful our first batch sold out in just 2 days. We have received a lot of positive feedback from our customers, some returning after using the previous versions.

"We find the majority of users track their cats every 10 minutes or so for the first few days to build up a picture of where their cat spends most of its time and then put the Halo in Locate mode to conserve power and ‘ping’ it for ad-hoc location updates”

The Halo costs £95 and comes complete with PAYG sim, safety collar, charger and charger cable and 1 month free access to the optional web platform (thereafter £25 per year)

PawTrax will also soon be launching Version 2 of their popular TAGZ GPS collar for dogs.
