One unique feature of the Garmin Forerunner 405 is the use of a touch screen to change views (like an iPhone) rather then buttons. On the down side, the touch screen will not work if its wet - which leads to some of the customer comments you see below.

Customer Reviews

Here''s what customers are saying about the Garmin ForeRunner 405 heart monitor watch:

...I''ve been using the watch for about a month now, almost daily. The watch itself is great. Great functionality, great specs, very useful. BUT - and there''s always a but - the watch basically freezes up when it becomes wet...

...The gadgets and gizmos that are out there for fitness and training today are simply tools. No serious athlete would stake their entire training plan on one device or gadget. Still, I think that Garmin has created one of the most reliable products out there for the functions you get. There are more accurate tools for measuring pace, power, etc., but if you''re looking for the GPS functionality, Garmin is the smart choice...

...Overall, this is a terrible product and if you really want to get a GPS enabled running device, I would highly recommend you buy the Garmin 305. It is much cheaper and while it does not look as good, the size will not bother you after a couple of wears and it will work flawlessly for you...

Get your skin wet

Some problems may be caused by dry skin or exercising in the winter. If it''s hot enough the monitor will begin sending your pulse to the heart monitor watch once you start to sweat. If you don''t sweat a lot, some advocate licking the strap before you start exercising, squirt some water between your skin and the strap or you can use a little heart monitor gel.
