If pvc is hard to locate once sunk.....

At best the GPS units are accurate to within PLUS OR MINUS 3 meters only 95% of the time. You may have found the 5% of the time when the accuracy was way off.

Another source of huge errors between two different GPS unit is the DATUMS. If one gps is using a 84 datum and the other is using the 27 datum then the readings can be off by hundreds of feet. Make sure that both units are using the same datum. You can find out in the manual how to set the datums for each gps unit.

Also the readouts can be in Hours, Min, Sec or in Decimal Hours. There is a difference between these two types of readouts. You can generally change the readout type in the setup page on your gps. Again see the manual to find out how to do this.

Each unit should still get you back to the same spot even if the readings on the display are different. Each will still get you back to the waypoint and within 3 meters of the spot 95% of the time.

Once they were set I would come back in looking for them all the while the bouy is still in the middle of them. I first set my handheld GPS and also the one in my dash and store the way points. Now from what my graph shows it does not look like a regular brush pile but broken up signals. But it still shows up. If you know what to look for . I also write down my coordinates like Moose said. Now heres what I don't understand-- I have a Garmen 12 handheld and a Lowrance Global Map 2000 indash. The coordinates are differant on the same marked waypoint? I write both down and differentiate which one I took the reading with. I don't want to take a chance of losing the beds!Good luck!

We have made PVC beds and have had good success. The darker the PVC the faster algae will form. We put out 35 last year and could find them all with a fish finder and landmarks.

This year we are using Bradford Pear trees. Some have been out for a month and a half, and they ae covered with growth. The jury is still out on how long the wood holds up.

TAZ,
I have the Garmin 12 also and use it icefishing and hunting all the time but I've noticed that it does get me in the general area but I have to do the leg work to find my spots I THOUGHT I marked. Do you also have this problem? I can see being off 5 -10 feet but it seems like I'm always not even close on the GoTo mode.

Imnich- Here is how I do it. I use the GOTO to get me within .01 of the target. Then I switch to the front page and watch the numbers change until I'm very close to what is in the waypoint list. I do this using my trolling motor and I'm constantly watching the LCR too. So far I.ve been able to find my beds with no problem. When I was using the GOTO all the way in I found myself running over my target alot so now I try to come in very slow without going over it. I realize this probably is not the best way but it has been working for me.

I dropped a couple during the summer and when I frist dropped them I couldnt see them at all. But after a few weeks and some alge build up There was no doubt where it was. I used a 10ft section of 4" and several 1" branches I capped off the top 6 or so branches and wieghted it down with 2 blocks. I used construction adhisive to keep the branches in place so they diddnt slide around in the 4". worked great!! the second time I went back I found it without a problem and to my surprise when I looked overboard I could even see it about 4 feet down. The bad thing is I havent fished it. I am more into Striper fishing.

I put out pvc laps the last few years and was also worried about the ease in finding my expensive laps in deep water. What I did was to cap off the end of some of the pipes so that they would hold a large air pocket to make them more visible on my fish finder. Also, this helped keep the lap more upright and spread the pvc branches. Good luck!

I personally like them being hard to see. The lake 's are getting more crowded all the time and if I can keep a few spots to myself well---. Thats why we put them out in the winter! I have two lake maps also. One is mine and the other is the one I use if someone wants to see where to fish. I write all over mine with GPS points and also I will use a laser if I'm close enough to land where I can get a good mark .

by laser i assume you are talking about a rangefinder....

Yes, I have a Nikon that is accurate to 400yds plus or minus 18". I 've found that it works great! I will get two readings usually at 90degrees to the beds . I'll usually add 10 yds to one of the measurements so I can come in and anchor and be within casting of the bed without spooking it.It's great in small bays .
