Question: My new Swami 4000 unit won't turn off right away when I want to turn it off. takes more than 10 min to power down. Is this normal?
Document: Personally, I highly discourage anyone from purchasing the IZZO 4000. I used the IZZO 3000 for 4 years and was very pleased. So I decided to upgrade to the IZZO 4000. The 4000 was a failure from day one. It takes over 5 minutes of pressing the on button for the unit to turn the power on. Once the unit has powered up, it takes 2 to 3 minutes and continuing pressing the play button to get the course to display.
Right out of the box this Swami unit did not work properly. A real lemon you might say. How unfortunate of me. The first problem I had was it did not power off and unit stayed on. Okay, I thought to myself, no big deal.After two days I went out and used the Swami for a round of golf. Swami found the course right away. Since my golf cart was equipped with a GPS unit, I compared the two units reads.
I wanted a gps device that was accurate but simple. I didn't want fees, maps, upgrades and advertising. Swami 4000 would be perfect for my needs if it was easier to turn on and off, but maybe its me.it also is not accurate on measuring my drives, but again maybe this is also faulty technique not electronics.
Although I've only had my Swami for three weeks, I am very impressed with the accuracy and simplicity of this golf tool. Highly recommend it! The price is right and it is very user friendly. I might mention the &#34;user friendly&#34; part is coming from a senior golfer who does not want to spend time trying to figure out any new gadgets! Very nice.
I had even checked to make sure the course was on the list and it was. Sent it back. Nice ideas. So far I have had nothing but failure with three different Izzo Swami GPS units.UPDATE!! 10/21/2012Received a different Swami 4000 from Izzo customer service and difference was night and day. Software was updated to include about 4000 new courses over the 4000 I previously had.Success at last. It picked up the course immediately and it was the first one on the list.
When I first got it, it was about 10-15 yards off. I was not pleased, but after I used it the first time I went to website and it had a new update the day before. I downloaded the update and now it works great. It is simple to use and I haven't messed with it any but am sure it will work just fine. My home courses came up right when I turned it on.
This is a great GPS tool on the golf course. Light weight and easy to use. It picked up my course in like 10 minutes the first time and the next few times it was right there. Also, it picked up True Blue right down the street. If you want an easy, give me the data I need and want tool, this is the one. Half price of the others
The Swami 4000 is perfect for what I need in a golf GPS device. For comparison sake, I am an 11 handicap and play every weekend. It is extremely accurate when comparing the unit to the yardage markers on the sprinkler heads. All I really want in a GPS is for it to give me yardages to the front, center, and back of the green and this unit is perfect.
There are plenty of free apps that include a similar database, scoring and even course maps.If you really need a standalone unit, then you can't go wrong with the Swami 4000, but if you need more (like maps), you'll want to invest in one of the higher end units like an Approach G6 (by Garmin). The Swami 4000 gets the job done, as long as "the job" involves the bare minimum - but I'd still recommend looking into a smartphone based option instead of this.
Unit takes 15 minutes to locate satellite, does not always advance to next hole , it is reasonably accurate ,take a long time adjust to new position  yardage fluctuates for a few minutes
Answer: Hold the ENTER button down, it takes about 3 seconds to bring up a Menu. Down arrow to highlight "Power Off", then press the Enter button. It shuts off.
