Which handheld reader should I buy?

Our hand-held reader range includes:

  1. The LID540 is our most inexpensive, “entry-level” pocket reader with no computer connectivity (i.e. a read-only reader) BUT it can only read ISO FDXB microchips. Because it has been optimised to read only ISO chips it reads them at an average distance of 60mm. 
  2. The LID560 is also an inexpensive, “entry-level” pocket reader with no computer connectivity i.e. a read-only reader that can read both ISO FDXB and FDXA microchips It will read all chips commonly used in Australia – both Trovan Unique (FDXA) chips (e.g. Trovan ID100 and Trovan Nanotransponders) and ISO (FDXB) chips. It reads the Trovan ID100 chips at about 50mm, ISO Midi-Chips at 40mm and the Nanotransponders at about 20-25mm and the read distance for the Nanotransponders is 20-25mm (this is a consequence of the much smaller antenna in the Nanos).  
  3. The LID573 is the same size as the LID560 but has USB computer connection for transferring stored data and has a similar read range to the LID560. You can purchase a Trovan Unique only version or the version that reads both Trovan Unique and ISO (FDXB) chips.
  4. The LID575 has a bigger antenna than the pocket readers and therefore a better read range. It has USB computer connectivity and data storage. It reads the Trovan ID100 chips at about 80mm, the ISO Midi-Chips at 60mm and the newer versions of the LID575 reader will read the Trovan Nanotransponder at 20-30mm
  5. The AREH5 is a lightweight high performance reader that is also capable of reading all commonly used chips. The standard version has RS232 computer connectivity. It reads the Trovan ID100 chips at about 100mm, most ISO chips at up to 200mm, the ISO MidiChips at about 150mm and the Nanotransponders at about 50mm.
  6. The GR250 is a bigger, more rugged and water resistant reader with superior read range and computer connectivity via RS232. The GR250 reader only reads Trovan Unique (FDXA) chips (e.g. Trovan ID100 and Trovan Nanotransponders). The GR251 version is the same as the GR250 but reads ISO (FDXB) chips as well as the Trovan Unique chips that the GR250 reads. The GR250 & 251 readers read the Nanotransponders at up to 80mm and the ID100’s at up to 240mm. The GR251 version will also read ISO Midi-Chips at about 130mm.

The software for the computer connection for the LID573, LID575, AREH5 and GR250/251 readers is free and allows you to download the animal identification/day/date and time data onto a laptop or other computer in an Excel spreadsheet format. There is an extra $122.00AUD (inc GST) for the communications cable for the GR250 & 251 readers.

With all of these readers (except the LID540 & LID560) we also have the capability of using keyboard wedge software to transfer a microchip number you have scanned into the search field of your management software on a laptop or desktop computer, to then press Enter and bring up the history and details of that particular animal.

The software of the LID573 & LID575 readers also allows you to use a Custom Coding function. You can assign custom codes for each transponder so that when the reader scans the transponder it will display a code that allows you to better identify the animal without going to a computer. It does nothing to the code of the transponder and that code will be displayed in the normal format if scanned by another reader. The custom coding is limited to a 30 alpha-numeric code. So, instead of 000876D6G it could display a code that either matches your current i/d system or use something like BTRWMFT1009LC0911 – Brush-tailed rock-wallaby, Male, First tagged & released October 2009 , Last caught and examined September 2011. You just change the codes with the PC attached to the reader and then go into the field and read each animal to verify its identity, origin, age, history, heath status etc depending on the custom code you use. Alternatively, you could use a code that fits best with your own system of identification to further make management easier.

So, the choice of reader basically comes down to:

  1. What types of chips do you need to read....Trovan ID100 FDXA only vs all types including ISO FDXB chips? If the latter, then eliminate the GR250 reader. If you need to read any FDXA chips then eliminate the LID540 reader. If you need to read the Trovan Nanotransponders, then eliminate the LID575 & LID540 readers.
  2. Do you need to store a number of reads in the reader for downloading later or just want a read-only reader? If the former, then eliminate the LID540 & LID560 readers.
  3. Is read range below 50mm useless if using the standard-sized transponders, then eliminate the LID560 and LID573
  4. Is Custom Coding useful to you? If so, then consider the LID573 or LID575 readers but remember the LID575 cannot read the Nanotransponders.
  5. Does the reader need to be splash-proof or waterproof? If relatively waterproof then consider the GR250 or GR251.
