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.

It may have a hefty price tag but the Triton 2000 offers plenty of features. The touch screen makes this device much easier to use than units that only have a navigational pad.

If you currently own a GO 720, then there is no real reason to upgrade, as most of the improvements are software upgrades. If you are looking for a high-end GPS with all of the latest features though, the GO 930 is excellent, if a little overpriced.

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.

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.

The Triton 400 provides the perfect companion for travelling and hiking. It doesn’t offer the luxuries of Magellan’s more expensive models, but it provides the necessities for successful travel at a fairly reasonable cost.

The XL adds a larger display to the already fantastic ONE unit. The new EasyPort mount and TomTom’s Map Share feature make this an enticing unit.

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.

Magellan’s Maestro 4250 provides an alternative to the more expensive, high-end TomTom and Garmin devices. Although it doesn’t provide the same level of polish as some of the better known brands, its features are functional and it provides everyday users with a viable GPS option.
