Smartphones handle many GPS tasks adequately.

Dedicated devices offer advantages: battery life, durability, cellular independence.

Decide whether dedicated device benefits justify additional equipment.

Accuracy Levels

Consumer GPS typically achieves 10-15 foot accuracy.

WAAS-enabled devices improve to 10 feet or better.

Dual-band GPS (newer devices) provides enhanced accuracy.

Tree cover, canyons, and buildings reduce accuracy.

Battery Considerations

Dedicated GPS devices last 12-24+ hours typically.

Smartphones GPS use drains batteries quickly.

AA battery devices enable field replacement.

Rechargeable-only devices require planning.
