Version 3 of the Theodolite Augmented Reality Navigation App for iPhones and iPads is now out.  Version 3 can now allow movie recording that you can have watermark overlay and set the quality of the video. It also has three large format stadiametric rangefinders for hunters and military users. This is a good app for your needs since it uses the power of smartphones and tablets and their built-in features to give you an even better navigation without buying other gear to do the same.

For a limited time, it is being sold at US$3.99 at iTunes, so you might want to take the chance to download it and be able to use it before the price goes up.

"Augmented reality navigation just took a giant leap forward with the new movie recording feature in Theodolite 3.0. It's another first for Theodolite, and continues the app's tradition of demonstrating new technologies, pushing the limits of iOS app development, and setting the pace for the competition.

Based on a centuries-old navigation instrument, Theodolite is a cool multi-function augmented reality app for the iPhone that serves as a compass, GPS, map, zoom camera (photo & movie), rangefinder, and two-axis inclinometer. Theodolite overlays real time information about position, altitude, bearing, and horizontal/vertical inclination on the iPhone’s live camera image, like an electronic viewfinder. Uses are endless, and the app is great for hiking, boating, hunting, golf, sports, sightseeing, navigation, and finding your way around. Theodolite is used extensively by surveyors, geologists, architects, engineers, competitive sportsmen, military personnel, and search and rescue workers around the world.

Theodolite has been featured several times in iTunes in 'Rewind: Hot Trends in Apps', 'The World Around You', and 'New and Noteworthy'. It has been the #1 selling Navigation app in the US and UK App Stores numerous times.

Theodolite lets you take geo-tagged camera images, screenshots, movies, and screen movies directly from the app, with 2X and 4X digital zoom options and fast buffered saves. You can choose to stamp geographical data and custom notes directly on photos and movies for later reference. View your current position on the built in map view, with standard, satellite, and hybrid modes, compass rose, and bearings.

Theodolite includes features for serious users like a zero reference angle mode, an A-B calculator for height, distance, heading, position, triangulation, and relative angles, data logging, e-mail export with KML data, system-wide clipboard integration, percent grade display, mil compass readout, optical rangefinders (including a mil-based reticle and sniper-style stadiametric graphs), colored lens filters to improve use in dark conditions and preserve night vision, military grid reference system (MGRS) coordinates, universal transverse Mercator (UTM) coordinates, and six latitude/longitude formats.

Theodolite lets you manage custom markers on the built in map, and allows you to share map markers and A-B points with other users of Theodolite and Theodolite HD via SMS text messages and e-mail. Data shared from map markers includes position and marker name. Data shared from A-B points include position, altitude, azimuth, elevation angle, and horizon angle. This powerful capability opens up a wide range of collaborative uses which include team land surveying, accident investigations, spotting of wild fires, triangulation of landmarks, and advanced tactical observation and targeting operations.

Theodolite works on any iPhone and the 4th generation iPod Touch. GPS functionality requires an iPhone 3G, 3GS, 4, or 4S. Compass functionality requires an iPhone 3GS, 4, or 4S. On iPhone 4, iPhone 4S, and iPod 4, data are augmented by the gyro, and the app uses high res artwork for the Retina Display.
