The iFinder Hunt C Plus from Lowrance is geared to Hunters due to its rugged, waterproof design, electronic compass and barometric altimeter . The iFinder Hunt has a 2.83” diagonal display with a 320x240 high-resolution color screen with a backlit keypad. It contains a 16 channel WAAS* antenna for exceptional accuracy. The iFinder Hunt C+ has a built-in US basemap showing highway detail and a general coastal outline of waterways, lakes and rivers. The basemap can be further enhanced with the included MapCreate mapping software or an optional detailed marine chart from Navioincs. The Hunt Color has an impressive built-in memory for up to 2000 waypoints and 100 savable plot trails with up to 10,000 points. There are also 42 different icons you can use to help identify your waypoints on screen. The iFinder Hunt is waterproof to IPX7 standards, so it is perfect for outdoor enthusiasts. The map has 40 zoom ranges from 0.02 to 4000 miles and the iFinder Hunt has dedicated zoom in/ zoom out keys. Other features include RealTree Hardwoods HD camo case, Built-in Microphone, audible alarms and backtrack feature to retrace your path. 1 year warranty. * While the regular GPS signal is available worldwide, the WAAS signal is currently available in the US only in open areas or on the water.

The issue wrt to being able to receive a signal in cover is a function of cover interfering with signal reception and satellite coverage. If you’ve got good satellite coverage you can get a signal through pretty heavy cover, but if the satellite coverage is poor the ability to receive a signal is impaired.

I would still bring along a map and compass, and the skills to use them.

True, but a receiver with a high sensitivity chip can hear and interpret signals much fainter than a regular receiver.

The newer high sensivity GPS's are amazing. Mine can get a 3D lock from the middle of my basement - not always, but quite often.

While at summer camp with my son's troop I was chatting about GPS's with Scoutmaster in the adjacent campsite. He said rather routinely "well of course we wouldn't get a signal under these trees ...". I said "I think my Garmin GPSMAP 60CSx would." So we each got our receivers (he had a nice little Magellan unit with a color screen & maps). Mine got a real strong 3D lock fairly quickly. His did get a 3D lock after a while, but it would fade in and out of 3D as he turned around and walked a bit.
