Lucky me! I found an AS GRHA50

Was reading/studying on one of the other forums last night and ran across a post where someone found a HB AS GRHA50 at Jet A Marina in Calvert City KY and said that he thought they still had more....WELL...!!

You can bet that I was standing at Jet A Marina's door when they opened this morning....and lucky for me...they had 1 left...I snatched it so fast the guy at Jet A Marina probably thought I was crazy.....

Then, I told him that HB had discontinued the AS GRHA50....he said that he only, ever, kept 2 of these in stock at any time.....

I wish they had more for you guys that want/ can't find one......

Now if I can just get that 1197 unit ordered.....

RnVinc- What are the advantages of that unit? Is Humminbird replacing with a better unit? I want to know if I need to be in panic mode because I just got 997cSI with the 16:D

I believe the grha50 is the new puck going out with all newer models. Just got an 957 and it came with the 50. My 997 that is 2 years old came with a 16. BPS is selling the 50 for $149.
Humminbird GR50 Advanced Fishing System GPS Receiver

Jethro, you must have purchased a used 997 if it came with the 16. Sorry!

how about a hummingbird gr50 for 123.00?

Jeepstero4- I purchased it new from Gander Mountain. End of season clearance price of $1350 plus got $100 in Gander Mountain "Gander Cash". Humminbird's website does list the GR50 as being supplied with the 997, so I was disappointed when saw on the 997 box the 16 was supplied. It was the last one the store had, and figured at that good a price, I would see how 16 actually worked and then could later get upgrade if not happy. So when I saw this thread started wondering what I need to keep my eyes open for.

Jethro,
I would see which GPS Receiver is inside first. Unless this is an older 997 unit than it should have an AS-GR50 inside. Open the box and see if it states “GR50” on top of the GPS Receiver.

There has been a little confusion on the model numbers in this post: there is the AS-GR50 and the AS-GRHA. The GR50 is what we currently produce and ship with each unit. The GRHA is a more accurate GPS Receiver than the GR50 and was discontinued due to low sales volume this year, so Rnvinc may have bought the last one in the country… Both the GR50 and GRHA are more accurate and will lock onto the satellites faster than the GR16 will.

Greg- Thanks for responding. The GPS puck has no identifying number on the top of the unit just "Humminbird GPS Accessory System". On the bottom of the puck is GR 16/4. Is there any chance of exchanging the 16 for newer model?

It’s a GR16 than Jethro. No, I don’t think that our Customer Resource folks can exchange a GR16 GPS Receiver for a GR50 GPS Receiver.

I think the GRHA accuracy is close to 1 meter while the GR50 is closer to 4-7 meters, (Greg, please correct my numbers)....

So the difference in accuracy may not be justified to some..(which is probably why HB states low sales volume for the GRHA at $199 each)....

If you want the higher accuracy it's going to be hard to find a GHRA because there is just not that many left in stock anywhere.....

I got lucky and read a post on Humminbird Side Imaging Forums - Index about a guy that happened to find one and knew that the retailer had, at least, one more...

It just so happened I was working nights and read the post at 2am saturday morning and was at the retailer's door when they opened at 8am....I got the last one he had and he didn't even know HB had discontinued the GRHA....

One other thing that I have learned here and especially at the other side imaging forums is that if you are ready to buy a Si unit....it would be in your best interest to contact the retailer and ask them which puck comes in the box with the unit you are getting ready to buy.....

And if you can get the person at the retailer to open the box and tell you the serial number....you can actually tell when that exact unit was built by HB....which will also tell you what should be in the box with that unit...

If the unit that the retailer is getting ready to sell you still has the 16 channel puck in the box...then that unit is older than Jan 2008... (Greg, please correct me on this also)....and that unit has probably been sitting on the retailer's shelf for nearly 2 years.....

What was the number on top of the unit that you purchased? I am looking for one also.

i was at nashville,tn bass pro and was looking at gps pucks and believe the one i was looking at was the ghra if thats what people are looking for i believe they had 2 left

Rnvinc,
I’ll have to do some research to find out when we stopped putting the GR16 in the box with the 997 units.


If those were GRHA’s at the Bass pro in Nashville than those that want them had better jump on them quick as there cannot be too many left out there!

i talked with HB today. they told me the reason for discontinuing the HA was because after testing it was no more accurate than the 50...not because low sales

Same here. It ok guys.

Chowan,
I would love to know the name of the person you spoke to about this. There is a difference in accuracy between the GR50 and GRHA, I’ve seen scatterplots, spreadsheet and the datasheet for the GPS engine that all show this difference. In addition, there have been a few Customers who have bought these and performed their own tests that confirmed that the GRHA is more accurate. Now to some people there may be no practical difference in accuracy – sort of like splitting hairs as the GR50 has an accuracy of 2.5 meters (8.2 feet) while the GRHA has an accuracy of less than 1 meter (3.2 feet). With a difference of 5 feet some may not see this as a difference in accuracy but I certainly do. The fact that this would cost you an extra $200 to have it (was only sold as an accessory) and the very good accuracy of the GR50 versus what most fishermen need accuracy-wise from their GPS units all resulted in a low sales volume, so it was dropped.

This accuracy difference is well worth the extra $ to me.......but I've always been accused of being a little different than some other people....

Thanks Greg...this info might be interesting to some here that are studying (like I am) about this technology and it's benefits to the fisherman....

The info of "How old is this 'brand new' unit and how long has this 'brand new' unit been sitting on the retailer's shelf"...is more of a "quirk" of my OCD mindset....(as you probably can tell by the thread I started / and continue to add to.... about 'Jumping into the Si market' )...I've picked a lot of brains...and am gratefull and value all info that I've gained from the info that thread has provided...)

When I buy a "brand new" $3000 unit, I want it to be right off the HB production line....instead of "brand new 2 years ago and sitting on the retailer's shelf since then"....

If nothing else...I feel that the HB production line expertise gained in 2 years of making and assembling the 1197's gives the 2010 models a distinct advantage over the same exact 1197's made in 2008....it's the natual order of production that doing something repeatedly over time gives exponentially improving hands on experience that makes newer units superior to older units of the same make.....

But, then again, like I said....I'm kinda OCD ......to a fault sometimes......lol...

Busy day today but I managed a few minutes of record digging and found that we started using the GR50 GPS Receivers in the 997 units in August of 2008.

The GPS Receivers are marked as the following on the top:
GR16 states: “GPS ACCESSORY SYSTEM” under the “HUMMINBIRD”
GR50 states: “AS-GR50 GPS MODULE” under the “HUMMINBIRD”
GRHA states: “AS-GRHA HIGH ACCURACY GPS” under the “HUMMINBIRD”
All of these have a dark gray (looks black to most folks) gasket between the upper and lower housings.
