The FD-250 has most of the basics and a few extra features that will serve you well, but the lack of responsiveness of the touch screen is an issue.

Laser’s Navig8r M35 is one of the best value for money GPS units we've come across. Don’t let its low price fool you: it is packed with features, including detailed mapping data and Australian-accented text-to-speech.

Although the eTrex H might suit those hikers who want nothing except the bare minimum, most will find it largely unusable. Inadequate functionality and no base map makes the unit extremely hard to use for anyone except the most experienced hikers, and the slightly more expensive Magellan Triton 200 is probably a better option.

The EVO is a welcome driving companion and, although not perfect, works well for providing early warning of safety hazards.

Costing the same as a low-end automotive GPS unit, the Triton 200 forgoes a touch screen as well as turn-by-turn and voice navigation in order to specialise in detailed mapping for outdoor activities. However, without the expandable memory required for detailed maps, the Triton 200 doesn’t provide the functionality necessary for more complex hiking and geocaching adventures.

Though a relatively cheap price point is sure to entice, several gaps in functionality make the GPSMAP 76 somewhat undesirable. It is functional if PC connectivity isn’t paramount, but for the most part it's worth paying more for the extra features.

The latest edition ONE features an even smaller design and an EasyPort mount, and supports TomTom’s Map Share feature. The ONE continues to set the standard for other GPS units to strive for.

As an entry-level unit the Moov 300 is a solid GPS device and an ideal choice if you happen to be on a budget. It may lack the bells and whistles of its more expensive counterparts, but it nonetheless provides a reasonable navigational experience.

Navigon’s 2110max is a reasonably low priced GPS, but the lack of text-to-speech and Bluetooth capabilities may be a deal breaker for some.
