MyFishFinder.com Just like iceshanty but warmer
I have one and didnt notice much lag on ultra scroll.
I haven't tried setting it at Ultrascroll since the instructions said it was for use when moving at higher speeds and gives "reduced image quality." I'll have to give a try.As it is, the lag isn't enough to bother me at all. But there is a bit of it, especially compared to my old-school flasher. I've had a chance to use the Garmin a few more times. I really like it!
for icefishing it makes it be a real time sonar.good luck.
They recommend using the Ultrascroll setting for ice fishing use. The instructions also recommended the frequency setting of "Dual Frequency 200/50 kHz". I had been using "CHIRP". That was why I was unable to select "Ultrascroll" and also why I was getting a huge 60˚ cone from the GT8HW-IF ice transducer (as evidenced by the cone coverage readout on the A-scope).
My gt8 is 16 to 24 degrees and doesnt have cone angles status in the ascope.i use chirp and have ultrascoll in my menu.i have a garmin striker 5 plus cv in the ice pack.
I also have the Striker Plus 5cv Ice Bundle. I just looked at all the settings this afternoon. I do have the proper (GT8HW) transducer selected. When I had the frequency set as "CHIRP" and no specific cone angle selected, my cone reading at the base of the A-Scope was 121' when I was fishing in 91 feet of water. Do the math. That's darn close to 60˚.But I think that reading may be incorrect. Today, I changed my cone angle setting to 16˚ and had a depth of about six feet and an A-scope reading of the cone size at five feet. At 16˚ I'm thinking that should have read something more like a little more than two feet.
The instructions say the read-out at the bottom of the A-Scope is the "Diameter of the sonar cone at the present depth." But if it was the area, as you say, that would make my 121' reading just about right for area of a 24˚ cone at 91' depth.
Thanks Dinky! Holy cow... I'm really embarrassed by my mathematics and won't even tell you how I came up with my incorrect figures. It's been more than a few years since I scored 98% on the NY Regents Geometry exam. I better get some remedial tutoring before I attempt any further computations!
I really think the cone diameter reading in the A-Scope is incorrect. When I was fishing this week, I was working my way off a steep drop-off that went from a small island down to 92'. As I drilled my way out towards deep water, my depth reading changed from 86' at one hole to 91' at the next hole, which was less than ten yards away. If my sonar cone was truly 121' wide, I should have still be reading 86' at that last hole, right? It seems as though a 121' wide cone would have still been covering that area.Anyway, it's all moot.
Ok, so it turns out I'm smart enough to find and use an online circle calculator but not enough to notice I was looking at circumference and not area.Even a straight wall you will see a depth increase as you move further away because the distance from the transducer to given depth is farther at the edge of the cone then it is at the center. That is why fish make hook shaped marks when you pass over them in a boat.I literally never pay any attention to that number on the A-scope, I forgot it was even there. It's not a piece of data that matters really. I adjust my settings to whatever works best at the time. You should try the 93cv on the ice sometime. I know it's overkill but I bet it would be easy on the eyes. Is that one of the ones that has like Netflix and stuff on it too?
Oh man auto-gain is the worst, it never works well for me. I always tune it manually to the conditions but even doing it that way bait can still mess it up if you have auto range on and the return is enough to trigger it. Have you tried out the Time Variable Gain settings? It's not good for tiny jigs in shallow water but in deeper water I like it.
