Ok, so is slowing down swing speed an effective way to deal with a machine that has poor recovery/response time? I'm buying my first detector tonight and I'm looking at a machine with manual ground balance/poor recovery/time and a machine with preset ground balance/fast recovery. I would rather go with the first option if I can compensate for the poor recovery time by slowing down my swing speed. Of course, I could test this myself if I had a detector right now but......... Thanks for your input.

How to deal with slow recovery/response time?

I'll agree with DLD....just purchase a machine with fast recovery speeds. Ask questions....Do your homework before you buy. Fisher F75/Teknetics T2 & Omega (when fitted with a DD coil) are a couple of recommendations. Usually, slowing down the sweep speed to compensate for poor recovery speed really is not effective, as the slowing of sweep speed diminishes the effectiveness of a discriminating motion detector. They are meant to be swept at a certain speed for maximum effectiveness (depth) Either a detector has fast recovery or it doesn't. And you can't compensate for it without giving something up in performance. IMHO
The only close exceptions to above are some Minelabs like the E-Trac & Explorer. They have poor recovery speeds but do very well with a slow sweep speed. They may be others I am not aware of.

I've sold or traded two detectors due to slow recovery time. It made pinpointing frustrating, especially in trashy areas. I've got a stable of older Tesoro

Slow recovery speed isn't necessarily bad if you understand it and compensate for it. Slow recovery time is mitigated by both slowing down your sweep and changing coil sizes and types to meet the target denseity of the site. That means as the number of target signals increase, you have to go down in coil size and/or coil type.
Where an 8" concentric coil might struggle, an 8" DD may do much better, and a smaller size concentric coil like a 6" or 7" might be perfect. So don't let recovery speed be your sole deciding factor in your purchase.
Good luck,
Mike

There is no such thing as "poor" recovery time.
It all depends on what you are hunting for and where you are hunting. Some of the best and deepest detectors are very slow because they need the time to process the information on deep targets. Faster recovery detectors are very good for hunting in trashy grounds and competition hunts and the most versatile detectors will have variable recovery speeds.
Unless your ground is mild, a ground balance is very important and if you are interested in recovering deeper targets, the slower recovery speed and a slower swing speed
are very important as well.

As a follow-up to Larry and Mike, I would also like to add the level of discrimination. My Ace 250 is constantly bombarded with the "slow recovery time"thing and I get a little puzzled. I run mostly in the Relics mode and I can take the coil and swing it like a golf club and as fast as I can and STILL get a good signal. Now I know that's not the same as recovery time-but let me go a step further. I have been in Coins mode and gotten a dime and nickel tone-which is the belltone quickly followed by the standard tone. Case in point number one. Now trash near the object is another point. HOWEVER, by being in Relics mode, which is just at iron nail reject, most effects of target masking and target "skip" are eliminated. Now you may get only ONE signal at a higher speed, but you WILL get a signal. I've even had coins near iron at least give a signal-no matter how weird-at this low disc level. THEN, by slowing down the sweep, the two signals will be isolated. I've done several posts called "Snipey and the Flying Ace"because I literally "fly" with the coil and, as Mike said, the little coils really snag the metal. Thanks for reading.

A fast recovery speed is overrated. With a slow recovery machine you just have to slow down your sweep speed and wiggle between targets to sniff out things nearby. You shouldn't be swinging like your launching a golf ball anyway. The Sovereign has a slow recovery speed yet I have no trouble seperating coins next to trash. Not only that, but it's Iron Mask ON feature is finding me coins laying with trash that no fast recovery speed machine I've ever owned seemed to be able to find. This is when they are laying right next to each other and the coil is in effect seeing them both at once. Now it's up to the machine's ability to process and seperate the two signals. That's where Iron Mask shines. Also, I believe a slow recovery machine does a better job of locking onto and sounding off to deep targets. Think of it this way...is it easier to read a street sign when you are driving at 100 miles per hour or at 30 mph? A slow recovery speed locks onto targets better IMHO and also does a better job of reporting the characteristics of the target as you can hear the little things about it such as uneven edges.
It depends where in the world you are hunting.In european conditions a detector with a high recovery speed and high sensitivity to smaller items is sometimes the only way to find low conductivity hammered coins in amongst areas with a high iron content.I own a sovereign and like critterhunter said it will pull coins out of the same hole as a piece of iron even though it has a fairly slow recovery speed.However,once in an area totally littered with nails and other iron trash and searching for small roman and hammered coins a detector like the sovereign is not so good........there are much better detectors for this kind of hunting and they all have fast recovery speeds.So in some areas fast recovery speeds may not be needed but in some types of hunting they are essential.
I disagree about the slow redcovery time not being detrimental. I read glorious things about brand X and bought one . The recovery time was painfully slow. So slow I couldn't stand it! Then I bought a brand Y and it had a tremendously fast recovery time and I love it! I didn't post the real brand names because I didn't want to start a brand war as it usually does. Onus

I used an ace 250 for some time which is slow as can be. I was very successful with it though. Just slowed my swing down. If I was to buy a started detector now, it would definately be a fisher f2. Very inexpensive but very good and fast.
